Title: Chloroformate esters prodn - by continuous reaction of alcohols with phosgene in aerosol phase
IPC: C07C67/00
Filed: 1971-12-08
Abstract: (A) Process for producing aliphatic, substituted aliphatic, cycloaliphatic, aromatic or araliphatic esters of chloroformic acid from the corresponding alcohols and COCl2, in which the reaction is carried out continuously in unidirectional flow in the aerosol phase under isothermal conditions and the chloroformic acid ester obtained is separated from HCl and excess COCl2. (B) Apparatus for carrying out the above process, consisting of a glass reactor column (1) which is divided into a reaction zone (2), a packed zone (3) and a condensation zone (4) and which is connected to means (5) for separating off the reaction mixture. Chloroformic acid esters are used in the pharmaceutical industry and other branches of the chemical industry (e.g. for producing compounds of the carbamate type). The esters are obtained in very good yields and very high purity. Residence times in the reactor are very short, so that small and therefore inexpensive apparatus can be used. In addition, only small amounts of substance are in the reactor at any one time and only a small proportion of this is COCl2, so that in the event of an accident only a small amount of COCl2 finds its way into the atmosphere.
