| Zusammenfassung: | In a process for the continuous preparation of chloroformic acid methyl ester by contacting phosgene with methanol at a temperature of up to 50 DEG C. in a reactor which contains chloroformic acid methyl ester as the solvent and in which phosgene is dispersed, the improvement wherein gaseous phosgene is dispersed by already formed and circulated chloroformic acid methyl ester into the reaction chamber by means of a dispersing device, and at the same time methanol is introduced into the homogeneous gas-in-liquid dispersion. |
