Description and Uses
Ethyl chloride is a colorless gas or liquid(below 12℃) with a pungent, ether-like odor and a burningtaste. Shipped as a liquefied compressed gas. Molecularweight 5 64.52; Specific gravity (H2O:1) = 0.92 (liquid at0℃); Boiling point = 12.2℃; Freezing/Meltingpoint = 2138.9; Vapor pressure = 1000 mmHg at 20℃;Flash point = -50℃ (liquid); Autoignitiontemperature = 519℃. Explosive limits: LEL = 3.8%;UEL = 15.4%. Hazard Identification (based on NFPA-704M Rating System): Health 1, Flammability 4, Reactivity 0.Slightly soluble in water; solubility = 0.6%.
Ethyl chloride is used as a refrigerant, as asolvent, in the manufacture of tetraethyl lead,and as an alkylating agent. It is also used asa topical anesthetic.
