What is the ratio of 7-chloro-1-ethyl-6-fluoro-1, 4-dihydro-4-oxo-quinoline-3-carboxylic acid to 5-chloro-1-ethyl-6-fluoro-1, 4-oxo-quinoline-3-carboxylic acid in this mixture?

The ratio of 7-bromo-1-methyl-6-chloro-1,4-dioxa-spiro [3.5] nonane to 5-bromo-1-methyl-6-chloro-1,4-dioxa-spiro [3.5] nonane in this mixture needs to be known by exquisite analysis.

Looking at these two substances, their structures are similar and their properties are similar. To obtain the ratio of the two, various chemical analysis methods can be used. For example, the method of gas chromatography can separate the two according to the difference in their distribution coefficients in the gas phase, and then calculate the ratio of their content according to the proportion of the peak area. Liquid chromatography can also be used. According to their adsorption and distribution in the stationary phase and the mobile phase, the two are separated, and the ratio is derived from the data of the peak response.

However, if you want to perform this analysis, you need to first prepare a pure standard sample for reference. The purity of the standard sample needs to be extremely high to make the analysis accurate. When operating again, the parameter setting of the instrument and the processing of the sample are all related to the accuracy of the results. A slight difference in parameters such as temperature and flow rate may cause deviations in the results.

The exact ratio of 7-bromo-1-methyl-6-chloro-1,4-dioxa-spiro [3.5] nonane to 5-bromo-1-methyl-6-chloro-1,4-dioxa-spiro [3.5] nonane in this mixture can be determined by precise analysis.

What are the differences in the physical properties of these two acids?

There are two kinds of acids today, and the difference in their physical properties should be analyzed in detail.

The first acid is also pure and transparent in color, like clear water, placed in a bottle, still without waves. Its smell is pungent, and when you smell it, you want to vomit, and there is a strong gas rushing to the nose. It feels greasy when touched, but it is unusually greasy. If you touch it accidentally, you will have a burning pain on your skin for a long time. Its boiling point is quite high, and it has been heated for a long time before it boils and vaporizes. And its density is greater than that of water. When you pour it into water, it sinks to the bottom.

The second acid is slightly yellow in color and slightly muddy, and it looks hazy. The taste is slightly lighter, although it is also pungent, it is slightly slower than the former. It does not feel greasy to the touch, but has a dry feeling. The boiling point is slightly lower, and it has not been heated for a long time, and there are bubbles that are born and vaporized. The density is less than the former, mixed with water, and can float on the water.

Furthermore, the solubility of the two is also different. The former dissolves very quickly in water, and when it dissolves, it exudes a lot of heat. If water is injected into this acid, the acid splashes, and it is dangerous, so the acid must be injected into the water and stirred while injecting. When the latter dissolves, the exotherm is less, although it needs to be operated in sequence, it is slightly less dangerous.

In terms of its volatility, the former is weakly volatile, and when placed in an open device, there is little quality loss over time. The latter is highly volatile, but when left for a long time, the amount decreases and the quality changes. The air is scattered in the air, and there is a pungent smell.

The two are also different in crystalline form. When the former crystallizes, it is mostly a regular block with a smooth crystal surface. The latter crystals are often finely broken grains, like gravel.

To sum up, the two acids have significant differences in color, taste, touch, boiling point, density, solubility, volatility, and crystal morphology. When using them, it is necessary to carefully screen them to avoid mistakes.

What are the chemical properties of this mixture?

The chemical properties of this mixture are particularly complex and need to be investigated in detail.

Looking at its various components, each has its own characteristics and is intertwined with each other, resulting in this unique mixed system. Some of the components are active and abnormal, and they are easy to react with other substances in common environments, or generate heat or emit light, and vary widely; while others are relatively stable, as if they are noisy and do not move, but this stability is not absolute. Under specific conditions, they can also break the calm and participate in the reaction.

For example, if it contains metallic substances, it often has good electrical and thermal conductivity. In chemical reactions, it is prone to lose electrons and is reductive. When it encounters with acids, it can often generate hydrogen gas, and violent ones can cause explosions. And if it contains some organic components, many of them are flammable, and can burn vigorously at suitable temperatures and sufficient oxygen to form products such as carbon dioxide and water. And between organic molecules, or due to the unique properties of chemical bonds, various reactions such as addition and substitution can occur, resulting in novel compounds.

Re-discussion of the salts that may exist in the mixture, which may ionize anions and cations in aqueous solutions. These ions can move directionally under the action of an electric field, making the solution capable of conducting electricity. Different salts have very different chemical properties due to the different ions they contain. Some salts can react with bases to form new salts and new bases; some react with acids to produce gases, precipitation or other changes.

In addition, the interaction between the components in the mixture cannot be underestimated. Either due to the forces between molecules, the physical and chemical properties of each other are changed; or due to the formation of special structures such as complexes, the characteristics of a single component are completely different. To be sure, the chemical properties of this mixture are like an intricate picture, and only through scientific methods and detailed analysis can we understand its mysteries.

In what fields will this mixture be used?

Mixed things have a wide range of uses and are useful in various fields.

In the field of craftsmanship, this mixture is often used for casting tools. To cast a strong weapon blade, you need to combine iron and other things, adjust the ratio, refine it and cast it, so that you can get a sharp and tough weapon. Like the ancient good sword, craftsmen mixed with iron, black iron, cold iron, etc. After thousands of tempering and hundreds of tempering, they can cast a famous sword, which can be used in battle, slashing the enemy and breaking armor, and invincible. And when making armor, this method is also used to mix metal, making the armor both light and strong, and ensuring the safety of soldiers.

In the business of building cities and houses, mixtures are also indispensable. Soil, stone, lime, etc. are mixed to make plaster, which can be bonded to bricks and stones. The construction of city walls relies on this plaster to make bricks and stones closely connected and resist foreign enemy attacks. When building houses, plaster is filled between the cracks of bricks, making the house strong and durable, and difficult to invade by wind and rain. It is also mixed with wood and soil and stone, rammed into the wall, which is warm in winter and cool in summer, providing a stable place for the dwellers.

In the land of farming, there are also mixtures. Farmers often mix manure, plant ash, etc. and apply them to the fields. The manure nourishes the soil, and the plant ash adjusts acid and alkali, and supplements potassium. The two are mixed to make the soil fertile and keep the crops thriving, and the harvest is expected. And during irrigation, or use canal water to mix pond mud and introduce it into the field to fertilize the field and moisten the soil, which is beneficial to the rooting and seedling of crops.

In the process of alchemy and pharmacy, the mixture is also the key. Alchemists mix all kinds of gold stones and herbs, and refine them through water and fire to seek elixirs for longevity. Although the wish of longevity is difficult to achieve, the method of pharmacy is much inspired. Healers mix herbs to make prescriptions to treat various diseases. Such as ephedra, cinnamon branches, etc., which can be mixed to solve the surface, dissipate wind and cold, and cure colds.

From this point of view, this mixture is useful in many fields such as manufacturing, city building, farming, medicine, etc., and is actually indispensable in the world.

How is this mixture prepared?

If you want to make this mixture, you need to follow a delicate method. First, prepare all the things you need, and examine its quality and properties in detail. Everything has its own suitability, and you must choose it carefully to get the best effect.

If you make a mixture of metal and wood, you should use the strength of gold to supplement the toughness of the wood. First melt the gold into a liquid, and its temperature should be appropriate. It should not be overheated to cause the gold to damage its properties, nor should it be too cold to cause the liquid to flow. The wood should be selected with a straight texture and a dense texture, and it should be cut to a moderate shape. When the gold liquid is ready, slowly pour it on the wood, so that it is evenly wrapped, and then let it stand and cool, so that the two blend seamlessly.

If it is a mixture of water and fire, the water should be clear and pure; the fire should be controlled by the strength of the flame. Use water in a heat-resistant vessel, gradually move close to the fire, and the fire should not be fierce, so as to prevent boiling overflow. At the same time, pay attention to the change of water, adjust the size of the fire in a timely manner, so that the water can boil slowly and not be impatient. Or add herbs, ores, etc., to control the heat and time according to their nature, so that water and fire can be combined, and different qualities can be produced.

As for the mixing of soil and stone, the soil should be selected from those that are fat and delicate, and the stone should be firm and warm. First, the gravel should be made into grains, the size should be suitable, and it should be fully stirred with the soil. In the meantime, an appropriate amount of water can be Stir it finely, and then it can be shaped as needed, or exposed to the sun, or placed in a kiln for micro-baking to make it firm.

To make this mixture, every step needs to be careful, observe the changes of things, and let it be done, in order to become a delicate product.
