Lactonitrile Chemical Properties,Uses,Production
Chemical Properties
Lactonitrile, is soluble in water and alcohol, but insoluble in diethyl ether and carbon disulfide. Lactonitrile is used chiefly to manufacture lactic acid and its derivatives, primarily ethyl lactate.
Uses
It is used primarily as a solvent, and as an intermediate in production of ethyl acetate and lactic acid.
Production Methods
Lactonitrile is derived from acetaldehyde and hydrocyanic acid.
General Description
Straw colored liquid. Used as a solvent /intermediate in production of ethyl lactate and lactic acid.
Air & Water Reactions
Water soluble.
Reactivity Profile
Lactonitrile is incompatible with strong acids, strong bases and strong reducing agents. Lactonitrile is also incompatible with strong oxidizers. In the presence of alkali, Lactonitrile evolves toxic compounds. .
Health Hazard
Extremely toxic by oral, skin, or eye contact.
Fire Hazard
Cyanide fumes released when heated to decomposition. Avoid alkali, oxidizing material.
