"Tiangong Kaiwu" contains: "Alum, what are the physical characteristics of 2-water-5- (1-methylethyl) -?" This question is quite strange, so let me explain it in detail for you.
Alum is a chemical thing. Although ancient books did not describe its structure with the precision of modern chemistry, it also has many applications in production and life. This "2-water-5- (1-methylethyl) -" alum, according to modern chemical principles, may be an alum compound with a specific structure.
Its physical properties are first related to the form. The common alum is mostly crystalline, and this alum may also be in the crystalline form, with a regular geometric shape, due to the crystalline structure. The color, or depending on the elements contained and the condition of the crystalline water, varies, or is colorless and transparent, or has a little color, such as light blue, light green, etc., are determined by its internal composition.
Another is solubility. Alum is mostly soluble in water, and this alum must also be able to dissolve in water to form a clear or colored solution. Its dissolution process may have endothermic and exothermic phenomena, related to its thermal effect of dissolution. And the solution after dissolution may have certain conductivity, because the alum ionizes ions in the water.
In terms of hardness, the crystals of alum are usually not extremely hard in texture, or can be scratched with hard objects to leave marks, nor are they fragile. They have a certain crystal strength to maintain their shape.
Melting point is also an important physical property. Alum species have different melting points due to their different structures. This particular alum, presumed to have a relatively moderate melting point according to its structure, is heated to a certain temperature to change from solid to liquid, and a phase transition occurs.
As for the density, compared to common water, the density of alum is higher. When placed in water, it should sink at the bottom, depending on the degree of compactness of its molecules or ions.
Although these various physical characteristics were difficult to accurately measure in ancient times, craftsmen, warlocks, etc. may also be able to observe them in practice, providing assistance for the production and craftsmanship of that time.

The main use of dihydro-5- (1-methylethyl) - is related to many fields, and it is particularly crucial in the preparation of alchemy and medicine.
In alchemy practice, it plays a significant role in reconciling human qi and stimulating inner potential. According to the alchemy classic "Shentong Agreement", the human body is like a small world, and it needs to reconcile yin and yang with various spiritual objects. This substance may help practitioners achieve a higher state. By regulating the circulation of breath in the body, it is like carefully reconciling all elements in an alchemy furnace, promoting the body and mind to achieve an extraordinary harmony, so as to more smoothly embark on the road of alchemy practice and comprehend the profound meaning of life.
In the field of pharmaceutical preparation, it plays an indispensable role. Many traditional medical codes record that this substance has a unique chemical structure and active ingredients, which can become a key raw material for the preparation of many special drugs. Or it can be targeted at specific diseases, such as poor qi and blood, meridian blockage, etc., to exert unique curative effects. Through the refining and processing of modern medical technology, its active ingredients are integrated into medicines, just like the ancient method of processing medicinal pills, with precise proportions to achieve the best medicinal effect, providing strong support for patients to relieve pain and restore health. Its application in the field of medicine is like a key, which is expected to open the door to conquer many difficult diseases and contribute unique strength to human health and well-being.

To make this thing, you need to follow the following methods. First prepare all kinds of materials, and the materials used are exquisite. Among them, the "hydrogen" used is preferably pure. When preparing, you can use the electrolysis of water, the yin and yang diodes to guide it, and the yin obtains hydrogen and the yang obtains oxygen. This is a common method.
As for "boron", it is mostly derived from boron ore. After refining and purifying, impurities are removed to obtain usable boron. The refining techniques are divided into fire and wet methods. The fire method uses high temperature melting ore to separate the boride; the wet method uses acid and alkali and other reagents to dissolve the ore, and then through various steps, extracts and crystallizes, and finally obtains pure boron. < Br >
For " (1-methylethyl) ", it can be prepared by an appropriate organic reaction. It is common to start with ethanol and methanol. After catalytic reaction, the reaction conditions, such as temperature, pressure, catalyst type and dosage, are adjusted to cause the reaction of condensation between the two, and the desired (1-methylethyl) group is generated.
When preparing this product, the prepared hydrogen, boron and (1-methylethyl) are placed in a special container in an appropriate proportion. The container material should be temperature-resistant, pressure-resistant and do not react with various reactants, such as special glass or metal alloy containers. Then, react at a specific temperature and pressure environment. Temperature control is crucial. If it is too low, the reaction will be slow, and if it is too high, side reactions will easily occur. Generally speaking, it is maintained in a suitable temperature range and regulated by precise temperature control equipment. The pressure also needs to be stable, which is achieved by pressure control devices. At the same time, depending on the reaction process, a specific catalyst may be added to accelerate the reaction and improve the yield of the product. During the reaction, closely observe the reaction phenomenon. When the reaction is complete, the subsequent steps such as separation and purification will remove impurities such as unreacted raw materials and by-products, and finally a pure 2-boron-5- (1-methylethyl) product can be obtained.

In order to make this substance, many matters need to be paid attention to during storage and transportation.
First, this substance contains "cyanide", and cyanide is very toxic. When storing, make sure that the container is tightly sealed to prevent leakage and poison, endangering people and things around. The storage place should be dry and well ventilated, away from fire and heat sources, because if it encounters hot topics or open flames, it may cause dangerous chemical reactions.
Second, " (1-methyl ethyl) " related ingredients, the substances involved in such organic groups are mostly volatile and flammable. When storing, it needs to be stored separately from oxidants, acids, etc., to avoid chemical reactions caused by mixed storage. During transportation, it is also necessary to prevent severe vibration and collision to prevent the container from being damaged and causing it to evaporate and leak. Vibration or collision may cause changes in the internal structure, resulting in unpredictable reactions.
Third, the overall material is also particular about the storage temperature. If the temperature is too high, it may cause the volatile components to increase and the reactivity to increase; if the temperature is too low, some ingredients may solidify and crystallize, which will affect its subsequent use performance. Therefore, it is necessary to control it in a suitable temperature range according to its physical and chemical properties.
Fourth, the vehicles and containers used during transportation must be strictly inspected to ensure that there is no damage and no potential leakage. And the transportation personnel should be professionally trained and familiar with the dangerous characteristics of the transported substances and emergency treatment measures. If there is an emergency during transportation, such as leakage, it can be responded to quickly and correctly to reduce the harm.
In short, the storage and transportation of this item should be done with caution and strict adherence to relevant norms and requirements to ensure safety.
