Abstract
PURPOSE: To obtain the titled compound which is a raw material for preparing urethanes, carbonates, etc. safely and hygienically by easy operations, by reacting trichloromethyl formate with an aliphatic alcohol.
CONSTITUTION: Trichloromethyl formate is reacted with an aliphatic alcohol, e.g. methanol or ethanol, to give an aliphatic chloroformate. The reaction is carried out in an inert organic solvent, e.g. n-hexane in the presence of a compound containing nitrogen at -10W+40°C. A heterocyclic compound having one or two tertiary nitrogen atoms, e.g. pyridine or quinoline, or aliphatic tertiary amine, etc. may be cited as the catalyst. This method is a highly safe method due to no need of handling the toxic carbonyl chloride in the gaseous state. The resultant titled compound is also useful as a raw material for preparing agricultural chemicals, medicines and dyes.
