Propionic anhydride
Chemically colorless liquid.
Melting point - 45 ℃, boiling point 167 ℃, relative density 1.0125 (20/4 ℃), the refractive index of 1.4038, flash point 73 ℃.
Soluble in water, soluble in methanol, ethanol, ether, chloroform and alkali.
Propionic acid as acylating agent c USES in medicine, spices, and manufacture of special esters in the pharmaceutical industry for the production of propionic acid Angle on the (antibiotics), testosterone propionate (male hormone deficiency), drostanolone propionate (cancer), all roads lead to Rome beauty of acid chloride pine (adrenal cortical hormones) and propionic acid betamethasone (adrenal cortical hormones), etc.
In organic synthesis, it is also used as a dewatering agent for nitrification and sulfonation, which is used to make alkyd resin and dye.
It is used mainly as an esterifying agent, nitrifying or sulfonated dewatering agent, and also used in the production of alkyd resin, dyes and drugs
Purposes as acylating agent used in medicine, spices, and special c esters such as cellulose propionate production in medicine, can Angle of propionic acid on the antibiotic medicine, treatment of the male hormone deficiency of testosterone propionate, cancer drugs drostanolone propionate, adrenal cortex hormones of the beauty of propionic acid chloride and 2 times he propionate, etc Propionic acid as acylating agent c used in medicine, spices, and special esters such as cellulose propionate on pharmaceutical production with propionic acid Angle on the antibiotic medicine, could be a cure for male hormone deficiency of testosterone propionate, cancer drugs drostanolone propionate, adrenal cortex hormones of the beauty of propionic acid chloride and 2 times he propionate, etc
Methods of production of propionic acid in 235 ℃, 8 x 105 pa under heating dehydration.
Also can be made of sodium propionate heating reflux 4 h with propionyl chloride, then through distillation, fractionation, collected 165-169 ℃ fraction is the propionic acid anhydride.
