ABSTRACT:
A continuous process for producing high-purity methyl chloroformate, by reacting liquid methanol with an excess of phosgene at no more than 20.degree. C., preferably about 15.degree. C. Phosgene is absorbed in a large circulating load of pre-formed chloroformate that has also methanol added to it. The product stream is treated to remove light ends, and a 98% pure product results.
