Butyric Anhydride CAS 106-31-0

1. Butyric anhydride is a versatile acylating agent used to synthesize butyrate esters for perfumes, flavors, and pharmaceutical intermediates like the gallbladder contrast agent iodopanoic acid .
2. Butyric anhydride CAS 106-31-0 acts as a raw material for producing cellulose acetate butyrate plastics, textile auxiliaries, varnishes, and disinfectants .
3. Butyric anhydride serves as a fumigant to drive bees from hives and is used in research for preparing dye-sensitized solar cell components .

1. Store Butyric anhydride in a tightly sealed container under inert gas in a cool, dry, well-ventilated place, as Butyric anhydride is moisture and air sensitive .
2. Keep Butyric anhydride CAS 106-31-0 strictly away from strong oxidizing agents, strong bases, alcohols, and amines, and avoid any contact with water due to violent reaction .
3. Handle Butyric anhydride using appropriate personal protective equipment including chemical-resistant gloves (butyl-rubber), tightly fitting safety goggles with face shield, and in a fume hood to avoid breathing vapors .

1. Isolate the spill area (at least 50 meters/150 feet for liquids), eliminate all ignition sources, and contain Butyric anhydride using dry inert absorbent material like dry sand, covering with a plastic sheet to prevent contact with rain .
2. Collect absorbed Butyric anhydride CAS 106-31-0 using non-sparking, explosion-proof tools into sealed, labeled corrosion-resistant containers; do NOT flush with water .
3. Personnel cleaning Butyric anhydride spills must wear full protective equipment including self-contained breathing apparatus, prevent entry into drains or waterways, and dispose of waste according to hazardous material regulations (UN 2739, Class 8, PG III) .

1. Butyric anhydride is corrosive (GHS05, Danger), causing severe skin burns and serious eye damage (H314, H318), with an NFPA health rating of 3 (serious hazard) .
2. Butyric anhydride CAS 106-31-0 is a combustible liquid (H227) with a flash point of 87-90°C (188-190°F), reacts violently with water to form butyric acid, and may be harmful if swallowed (H302, LD50 oral rat: 8,790 mg/kg) .
3. Combustion of Butyric anhydride produces toxic carbon oxides; Butyric anhydride may be corrosive to metals (H290) and may cause damage to organs (lungs) through single exposure (H371) .
