Butyric anhydride;Butanoic acid anhydride;Butyryl oxide;Butanoic anhydride
Molecular formula : C8H14O3
MW : No. Using 158.20
CAS-31-0

nature : a transparent colorless flammable liquid, low toxicity. The temperature -75 ° C (-65.7 ° C Freezing Point), the boiling point 199.4-201.4 ° C (101.3 kPa), the relative density of 0.9668 (20 / 4 ° C), the refractive index of 1.4070, vapor pressure 39.4Pa (20 ° C), the flash point of 86.1 ° C Water soluble and acid decomposition generation, dissolved in ether.

Preparation : Mr anhydride may be small and sodium chloride were generated from heat, or by acid and acetic anhydride Preparation. Butyric acid and acetic anhydride in the presence of a catalyst heated reaction in the small liver, vice-acetic acid, then separated, purified product derived. The other method is acid with a sulfur chloride, or keto acid and ethylene (or diethyl gestrinone) reaction, or acid and methyl acetylene reaction, can get a small anhydride.

purposes : Preparation of cellulose acetate small, acid esters and fragrance raw materials. In Medicine for gallbladder iodine contrast agents pantothenic acid raw materials.
