Physicochemical properties:
1. Colorless liquid and irritating dour.
2. Melting point 16.6 ℃; boiling point 117.9℃; Flash point : 39 ℃.
3. Solubility water, ethanol, benzene and ethyl ether immiscible, insoluble in carbon disulphide.
Storage:
1. Stored in a cool, ventilated warehouse.
2. Keep away from the fire, heat. The cold season should maintain a temperature higher than 16 DEG C, to prevent solidification. During cold season, temperature should be maintained above 16 DEG C to prevent/avoid solidification.
3. Keep the container sealed. Should be separated from the oxidant and alkali. Mixing should be avoided by all means.
4. Use explosion-proof lighting, ventilation facilities.
5. Mechanical equipment and tools that prohibit the use of easy to produce sparks.
6. Storage areas should be equipped with emergency treatment equipment and suitable housing materials.
Use:
1.Derivative:Mainly used in synthetising acetic anhydride,acetic ether,PTA, VAC/PVA,CA,ethenone,chloroacetic acid,etc
2.Pharmaceutical:Acetic acid as solvent and pharmaceuticalraw materials, mainly used for production of penicilin G potas-sium, penicilin G sodium, penicillin procaine, acetanilide,sulfadiazine, and sulfamethoxazole isoxazole, norfloxacin,ciprofloxacin, acetyl salicylic acid, non phenacetin, prednisone,caffeine, etc.
3.Intermediate:acetate ,sodium hydrogen di,peracetic acid,etc
4.Dyestuff and textile printing and dyeing:Mainly used inproducing disperse dyes and vat dyes,and textile printing anddyeing processing
5. Synthesis ammonia: In the form of cuprammonia acetate,used in refining syngas to remove a litl CO and CO2
6. Photograph: Developer
7. Natural rubber: Coagulant
8. Construction industry: Preventing concrete from frezing9. In addtin also widely used in the water treatment, syntheticfiber, pesticides, plastics, leather, paint, metal processing andrubber industry
f you are mentioned now, many people will be confused, saying that they do n’t know what this is, and some people even listen to their names to guess their functions. Is it possible for a wave of guessing a wave of this stuff?
Actually, there is a more broad and well -known name -acetic acid.
In actual use, ice acetic acid will not be applied to the brewing industry. Instead, because it is one of the most important organic acids in the world in the world, it has other, more wide and more diverse application areas and application channels. Essence
Its existence not only allows us to have a more flavorful dining table, but also allows us to become more convenient and smooth in terms of clothing, housing, traveling, medicine, medicine, etc., especially in industrial use. Impoles acetic acid is more. It is an excellent application.
Such as photographic pharmaceutical manufacturing, fabric printing and dyeing, rubber industry, dyeing industry, sugar food products, synthetic fiber, etc.
Therefore, many people know that acetic acid is because I have worked or studied in chemical -related fields; some people have been read in the composition table of certain preparations; some people are Understand and so on.
However, although it has such diverse and extensive uses, when buying ice acetic acid, some friends always feel that there is a problem with the price of ice acetic acid they purchased. Some people think they are expensive. Similarly, they all feel that they buy fakes or meet black -hearted manufacturers.
