Document Summary
Benzyl chloride was first obtained from benzyl alcohol and hydrochloride acid by. The earliest producers of benzyl chloride in the united states were. Heyden chemical company and allied chemical dating back to the middle of 1920s (kroschwitz and howe-grant 1979). Monsanto company), with plants in belgium (23,000 t/yr) and bridgeport, new jersey (40,000 t/yr), is the largest producer in the world (kroschwitz and howe-grant 1993). Benzyl chloride is manufactured by the thermal or photochemical chlorination of toluene (faith, 1975). In commercial practice, the chlorination of toluene is carried out either in batches or continuously (shearon 1949; kroschwitz and howe-grant 1993). The side-chain chlorination of toluene proceeds via a set of consecutive reactions. These reactions can be expressed by the following overall stoichiometric equations: The proposed reaction mechanism involves a series of free-radical reactions. All the possible reaction steps published in the literatures (huyser 1970; mcketta 1979; andr , Tournier and deglise 1983; march 1992) are shown as follows:
