1. Process for the production of gamma-chloroacetoacetic acid chloride from chlorine and diketene, starting from chlorine dissolved in an inert solvent and a diketene dissolved in an inert solvent in a molar ratio of chlorine to diketene of 0.9-1.2:1, characterized in that the starting solutions are continuously introduced in co-current streams into the reactor in such manner that the two solutions mix immediately and intimately resulting in a turbulent flow having a Reynold's number above 2500. |
