[Property]N-butyric acid is a low-level fatty acid, which is the fermentation product of butyrate when it is spoiled. Color oily liquid. It also exists in butter in the form of ester, with a content of 4%-5%. The relative density is 0.959 (20°C), the boiling point is 163.7°C (101kPa), the melting point is -4.26°C, the flash point (open cup) is 77°C, and the refractive index is 1.3984 (20°C). Soluble in water, ethanol and ether.
[Use]It is the raw material for synthesizing various butyrates and cellulose butyrate. In the pharmaceutical industry, it is used in the manufacture of contraceptives and gallbladder contrast agent iodopantothenic acid. It is also used in the preparation of spices, emulsifiers, fungicides, preservatives, tanning agents, plasticizers, grain preservatives, as well as solvents, extractants and decalcifying agents.
