What is the main use of 2-% cyanic acid-5-indigo?
Cyanic acid is toxic in nature, but it is also useful in general industrial fields. In metallurgy, it can be used to extract gold, which can cause gold to form soluble compounds, so that gold can be dissolved from stone, so that it can be extracted. In terms of synthesis, it is an important raw material, which can be used to synthesize compounds containing cyanide groups, such as nitriles, which can be further reduced to amines, carboxylic acids, etc. It is indispensable for the production of compounds, dyes, and other carboxylic acids.
Indigo, also known as indigo, is an ancient natural dye. Its main use is in dyeing. Since ancient times, people have used indigo to dye cloth. The color it dyes is deep and long-lasting, which can make the fabric have a special color and taste. Cotton, linen, cotton, etc., can be dyed with it to create exquisite dyes. Furthermore, in the field of indigo, indigo is also an important color material. In addition, in some industrial techniques, such as printed cloth, indigo is also the core material, which achieves the special charm of these works.

The physical properties of 2-% cyanic acid-5-1 are similar to those of cyanic acid.
Cyanic acid, under normal conditions, is a transparent liquid in the shape of a yellow color, and has a yellow color. The taste is slightly similar to bitter almonds. Its boiling temperature is low, 26 ° C. This characteristic makes it easy to use in normal environments. Cyanic acid can be mixed with water, ethanol, etc. in any proportion. This is because the cyanic acid molecules can form water molecules, so it has good solubility. Its density is also less than that of water, 0.69 g/cm ³. Those who need to pay attention, cyanic acid poisoning, small inhalation or exposure, may be life-threatening.
, as far as physical properties are concerned, it is usually solid in color, and the color is easy to distinguish. Its melting phase is high, and it generally needs to be melted under a specific high temperature. This characteristic shows that the crystalline phase of the crystal is fixed. The solubility of the crystal in water is poor, and it is mostly submerged in the bottom of the water, and it is rarely dissolved. However, in partial solubility, it can show a certain solubility, which is caused by the similar principle of dissolution of its molecules. In addition, the hardness of the crystal is not hard to grind, nor is it difficult to form the waxy, so it is easy to process and use. Its density is slightly higher than that of water, causing it to sink immediately when thrown into water.

What is the chemical properties of 2-% cyanic acid-5-5 algae? I can explain.
Cyanic acid is also a toxic chemical compound. Its chemical formula is HCN, which is often used to produce a transparent and easy-to-use liquid, and has a bitter almond taste.
Cyanic acid is acidic, but the acidity is very weak. It can be weakly produced in water, and its balance is affected by many factors. It is also primary, and can be oxidized to produce oxidants such as high acid, and it is oxidized by cyanic acid or carbon dioxide, nitrogen, etc.
As for algae, this is an ancient photosynthetic prokaryotes. Its chemical formation, the main component of the cell wall is peptidoglycan, which is similar to bacteria. Phytocytes contain photosynthetic pigments such as chlorine a and alginin, which can be photosynthesized, and the light energy can be converted to chemical energy, and carbon dioxide can be fixed to generate organic compounds.
Algae cells also contain biological macromolecules such as multi-protein, nucleic acid, lipid and polysaccharide. The physiological activities of protein cells, such as enzyme-catalyzed reaction; nucleic acid information, which controls the generation, reproduction and generation of cells; biological membranes such as lipid-forming membranes, which support the integrity of cells; polysaccharides play a role in cellular protection and other aspects. In addition, cyanic acid is important for the chemical properties of algae, but it is important for chemical and biological fields.

To prepare fenvalerate and pentachlorobenzaldehyde, the method is as follows:
First, the preparation of fenvalerate. Using dichlorovaleryl chloride and fenvalerol as raw materials, in an appropriate reaction vessel, add an appropriate amount of acid binding agent, such as triethylamine or the like. The temperature is controlled in a suitable range, usually between 20 and 40 degrees Celsius, and stirred to fully react. This reaction needs to be carried out in an anhydrous environment to prevent the hydrolysis of raw materials and products. When the reaction time is about the same, the reaction progress is monitored by thin layer chromatography. When the reaction is complete, it is extracted with an organic solvent, such as ethyl acetate, and then washed, dried, and distilled under reduced pressure. Pure fenvalerate can be obtained.
As for the synthesis of pentachlorobenzaldehyde, it can be obtained by hydrolysis of hexachlorobenzene as the starting material. Put hexachlorobenzene into a reactor containing an appropriate amount of sodium hydroxide solution, heat it up to a high temperature, about 100 to 120 degrees Celsius, and stir vigorously. During this hydrolysis process, one of the chlorine atoms of hexachlorobenzene is replaced by a hydroxyl group, and then acidified. The pH of the system is adjusted to acidity with dilute hydrochloric acid. At this time, the hydroxyl group is converted into an aldehyde group to generate pentachlorobenzaldehyde. After the reaction is completed, the product is purified by cooling, filtering, and recrystallization. The solvent used can be an ethanol-water mixed solvent, whereby high purity pentachlorobenzaldehyde can be obtained. < Br >
The synthesis of these two methods requires fine control of the reaction conditions and proper operation to obtain satisfactory yield and purity.

At present, the price of 2-mercaptoethanol in the city is about 20 to 50 yuan per 500 grams; 5-shows the price of cyanobacteria, about 5 to 20 yuan per gram. However, this is a common price in the market, and its price also varies depending on the quality, the time, and the distance of the place.
2-mercaptoethanol sold in the city is mostly used in chemical and pharmaceutical fields. If it is of high quality and pure, the price may be slightly higher; and if it is purchased in large quantities, it may also be discounted. As for 5-shows cyanobacteria, which are often used for scientific research and teaching, if it is difficult to cultivate and difficult to raise, the price will also increase.
In order to promote sales, merchants may have benefits from time to time, especially during holidays. And the price varies from place to place. In prosperous places, there are many businesses competing, and the price may be stable and appropriate; in remote places, the transportation cost is high, and the price may be slightly higher.
If you want to know the exact price, you can visit chemical shops, scientific supplies shops, or check it online. Compared with the price of various houses, you can get the right price and buy what you need.
