Propionic acid is an important chemical raw material. Propionic acid and its derivatives are widely used in the synthesis of tree esters, grain preservation, food and feed additives, spices.
The earliest propionic acid was prepared by condensation and separation from the gas produced by charcoal manufacturing and coal coking. In the 1950s, foreign countries developed the process of producing acetic acid by oxidation of light hydrocarbons. The product contains about 10% (propionic acid), which is obtained after separation and purification. In addition to the hydrocarbon oxidation method, the United States also has the method of carbonylation of ethylene, CO and H2 to synthesize propionaldehyde and further oxidation to propionic acid. Due to the development of low-pressure carbonylation process with rhodium phosphine complex as catalyst, propionaldehyde oxidation method has developed rapidly in recent years. This method is superior to the traditional high-pressure method with carbonyl cobalt as catalyst.
Propionic acid, also known as primary oleic acid, is a short chain saturated fatty acid with the chemical formula ch3ch2cooh. Propionic acid is a colorless, corrosive liquid with pungent smell.
Tert-butylalcohol(TBA), also known as trimethylmethanol, 2-methyl-2-propanol, etc., forms four isomers of butanol with n-butanol, isobutanol, and secondary butanol. The pure product is colorless crystal, colorless volatile liquid in the presence of a small amount of water, has a camphor-like odor, hygroscopic, flammable, and has higher toxicity and anesthetics than other alcohols. Soluble in most organic solvents, such as alcohols, esters, ketones, aromatics and aliphatic hydrocarbons, and water can form an azeotrope. These properties make tert-butanol a useful solvent and additive and one of the petrochemical products with a wide range of applications.
Dimethyl carbonate is a recently developed friendly green organic chemicals, widely used alternative phosgene the dimethyl sulfate Halothanes larger environmental hazards of chemicals used as carbonation and modulating agent, to meet the current requirements of the cleaning process. This article reviews dimethyl carbonate in pesticide and medicine and intermediates (such as furazolidone intermediate 3 - amino-2 - oral oxazolidinone, sulfonylurea herbicides, carbendazim, carbaryl ring ciprofloxacin intermediate 2,4 - dichloro-5 - fluorobenzoyl acetate, isocyanine) synthesis process green transformation.
Phenol is an organic compound, chemical formula C6H5OH, is a colorless needle crystal with a special smell.It's toxic, is an important raw material in the production of some resins, fungicides, preservatives and drugs (such as aspirin). It can also be used for disinfection of surgical instruments and excreta treatment, skin sterilization, itching and otitis media. Melting point 43�ºC, slightly soluble in water at room temperature, soluble in organic solvents; When the temperature is higher than 65�ºC, can be mixed with water in any proportion. Phenol is corrosive.
Calcium carbide is an inorganic compound, white crystal, industrial products are gray black blocks, cross-section purple or gray. It reacts violently with water, forming acetylene and releasing heat. Calcium carbide is an important basic chemical raw material, mainly used to produce acetylene gas. Also used in organic synthesis, oxyacetylene welding and so on.
It is called calcium carbide( CaC2). It is a hard lump and the cross section is dark grey or brown.
2. It is lumpy substance, its surface is a little deep gray, has slight nasty smell.
3. It can produce acetylene gas when met water, it can burn when meets fire.
4.The acetylene gas mix with air will form explosive gas (explosive range of acetylene gas in the air is 2.3% - 81%).
1.The main raw material for producing acetylene gas.
2.Cutting and welding for metal material.
synthesize polyvinyl chloride(PVC).
4.Fruit catalyst.
5.The basic material for organic synthesis and calcium cyanamide
6.Reacting with water to bring about ethine.
7. Reacting with nitrogen to product lime nitrogen.
8.The desulfurizer in steel industry.
