Application
1. Butyryl chloride is a key intermediate for synthesizing active pharmaceutical ingredients like benzoyl peroxide and benzophenone .
2. Butyryl chloride CAS 141-75-3 is used as an acylation reagent in organic synthesis and for preparing esters for the flavor and fragrance industry .
3. Butyryl chloride is employed in polymer chemistry to produce biodegradable polybutyrate and other specialty materials .
Storage and Precautions
1. Store Butyryl chloride in a tightly sealed container in a cool, dry, well-ventilated area away from heat, sparks, and open flames .
2. Keep Butyryl chloride CAS 141-75-3 strictly away from water, alcohols, strong bases, and strong oxidizing agents due to violent reactions and moisture sensitivity .
3. Handle Butyryl chloride using appropriate personal protective equipment including chemical-resistant gloves, safety goggles, face protection, and in a fume hood .
Emergency response to leakage
1. Isolate the spill area (at least 50 meters/150 feet), eliminate ignition sources, and contain Butyryl chloride using dry inert absorbent like sand, avoiding any water contact .
2. Collect absorbed Butyryl chloride CAS 141-75-3 using non-sparking tools into sealed, labeled corrosion-resistant containers; if spilled in water, hydrogen chloride gas may be produced requiring protective action distances up to 0.3 miles downwind .
3. Personnel cleaning Butyryl chloride spills must wear full protective equipment including self-contained breathing apparatus and dispose of waste according to hazardous material regulations (UN 2353, Hazard Class 3/8, PG II) .
Safety Information
1. Butyryl chloride is highly flammable (flash point 21°C) and corrosive, causing severe skin burns and serious eye damage (H314, H318) .
2. Butyryl chloride CAS 141-75-3 is harmful if swallowed (H302), toxic if inhaled (H331), and reacts violently with water, releasing toxic and corrosive hydrogen chloride gas .
3. Combustion of Butyryl chloride produces toxic fumes including carbon oxides and hydrogen chloride, and the compound may be corrosive to metals (H290) .
