Abstract
A process which can be used for producing thiolcarbamates is provided wherein the process comprises contacting a reaction mixture with a hydrocarbyl chloride such as, for example, benzyl chloride under a condition which is sufficient to produce a product mixture wherein the reaction mixture comprises carbonyl sulfide, an amine such as, for example, a secondary amine, a solvent; the solvent comprises a tertiary amine; and the reaction mixture, hydrocarbyl halide, and solvent are each present in an amount sufficient to effect the production of a thiolcarbamate. Optionally, the reaction mixture can also comprise a metal hydroxide. Further optionally, the product mixture can be contacted with a metal hydroxide if the reaction mixture does not comprise a metal hydroxide.
