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
As a colorless but irritating odor liquid, it also has strong acidity and corrosiveness. If we accidentally use our fingers or other skin surfaces to make direct contact with it, then the surface of the skin will be because it will be because it will be due to it. The irritation is directly foaming, and you need to seek medical treatment as soon as possible.
However, even if methic acid is relatively average in the public’s cognition, in real life, it is really one of the most widely used chemical products. In fact, there is a field of nomidic acid, and it has made a lot of contributions and has a very important position.
For example, in industrial fields such as pesticides, leather, dyes, medicine and rubber, as long as you pay attention to observation, you can find traces of methamphetamine.
The aqueous solution of methic acid and methic acid can not only dissolve metal oxides, hydroxide and a variety of metals, but also can also be dissolved in water, so it can also be used as a chemical cleaner.
In addition to the above applications, methic acid can also be applied to the following aspects:
1. Medicine: Vitamin B1, metharomazole, amino plasma, etc.;
2. Pesticide: powder rust nine, triazolone, triazol, triarazole, polyzazole, hyunzole, insectichal ether, etc.;
3. Chemistry: calcium methampite, sodium methampite, ammonium ammonium, potassium methampate, methampite, methalmamine, rubber agent, neosopaol, epoxy soybean oil, epoxy soybean oil, special pentagosyl chlorine, ivyl chloride,, special pentoprachromic acid, special pentoprachromicchromic,, special pentoprachromicchromes,, special pentoprachromicchromes,, special pentoprachromicchromes,, special pentoprachromicchromes, ivyl chloride, ivyl chloride, ivyl chloride, ivyl,, special pentopramlonholin, special pentopramlonholin, special pentopramlonholin, special pentopramlonholin, special pentopramlonchromic, and special pentagram, peptic acid chlorine, ivyl, Mainly painted agent, phenolic resin, pickled steel plate, etc.;
4. Leather: leather tannai agent, ash dewin and neutralizer;
5. Rubber: Natural rubber condenser;
6. Other: manufacturing printing and dyeing media, dyeing agents, treatment agents, plasticizers, food preservation and animal feed additives, etc.
