Method for the prepration of aliphatic chloroformates
Abstract:
A method for preparing an aliphatic chloroformate comprising, introducing a mixture of at least one aliphatic hydroxyl compound, phosgene, at least one solvent, and optionally at least one organic base into a flow reactor to obtain a unidirectional flowing reaction mixture. The at least one aliphatic hydroxyl compound comprises at least one aliphatic hydroxyl group. The unidirectional flowing reaction mixture is maintained at a temperature between about 0° C. and about 60° C. to produce a single product stream comprising an aliphatic chloroformate.
