Benzyl chloride Chemical Properties,Usage,Production

Chemical Properties Colorless to yellow liquid Usage An intermediate in the preparation of phenylacetic acid (precursor to phamaceuticals). Also a precursor molecule to benzyl esters which are used as plasticizer, flavorants, and perfumes. General Description A colorless liquid with an irritating odor. Toxic by inhalation and skin absorption. Flash point 153°F. Slightly soluble in water. Corrosive to metals and tissue. A lachrymator. Density 9.2 lb /gal. Air & Water Reactions A lachrymator. Slightly soluble in water. Reactivity Profile Halogenated aliphatic compounds, such as Benzyl chloride, are moderately or very reactive. Reactivity generally decreases with increased degree of substitution of halogen for hydrogen atoms. Materials in this group are incompatible with strong oxidizing and reducing agents. Also, they are incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides. Health Hazard Intensely irritating to skin, eyes, and mucous membranes. Highly toxic; may cause death or permanent injury after very short exposure to small quantities. Has been listed as a direct-acting or primary carcinogen. Large doses cause central nervous system depression. Fire Hazard Benzyl chloride burns but does not ignite readily. Benzyl chloride may ignite combustibles. When heated to decomposition, Benzyl chloride emits toxic and corrosive fumes. Some organic chlorides decompose to yield phosgene. Incompatible with active metals such as copper, aluminum, magnesium, iron, zinc, and tin and keep from strong oxidizing agents. Avoid contact with acids or acid fumes. Keep separate from oxidizing materials. May become unstable at elevated temperatures and pressures; may react with water resulting in some nonviolent release of energy. Polymerizes with evolution of heat and hydrogen chloride when in contact with all common metals except nickel and lead.
