Description and Uses
Benzyl chloride is a colorless to slight yellowliquid with a strong, unpleasant, irritating odor. The odorthreshold is 0.05 ppm. Molecular weight = 126.6;Specific gravity (H2O:1) = 1.10; Boiling point = 179.4℃;Freezing/Melting point = -43℃; Vapor pressure =1 mmHg at 20℃; Flash point = 67℃ (cc); Autoignitiontemperature = 585℃. Flammable Limits in Air:LEL =5 1.1%; UEL=14.0%.Hazard Identification(based on NFPA-704 M Rating System): Health 3,Flammability 2, Reactivity 1. Practically insoluble in water;solubility=0.05%.
Benzyl chloride is used in the manufacture of benzyl Compounds, dyes, artificial resins, tanning agents, phar maceuticals, plasticizers, synthetic tannins, perfumes, lubricants, and quaternary ammonium compounds. It is also an intermediate in the preparation of phenylacetic acid (precursor to phamaceuticals).
