Toxicity:Inhalation-rat LC50: 25 ppm/6 hours; peritoneal-mouse LD50: 405 mg/kg
Flammability characteristics:Flammable; spicy and irritating smoke is released in the fire; rapid hydrolysis in water
Explosive limit:vol% in air: 2.9
Odor:PUNGENT
Experimental Properties:VERY HIGH CHEMICAL REACTIVITY DUE TO PRESENCE OF STRAINED FOUR-MEMBERED LACTONE RING|DECOMP IN WATER & ALCOHOL
Air and Water Reactions:Slow reaction with water to form beta- hydroxypropionic acid.
Reactive Group:Esters, Sulfate Esters, Phosphate Esters, Thiophosphate Esters, and Borate Esters
Reactivity Profile:BETA-PROPIOLACTONE is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. This chemical may be incompatible with alkalis.
Flammable Limits:LOWER FLAMMABLE LIMIT: 2.9%|Class IIIA Combustible Liquid: Fl.P. at or above 140°F and below 200°F.
