| titleOfInvention | Process for the production of γ-chloroacetoacetic acid chloride |
| abstract | A process for the production of gamma -chloroacetoacetic acid chloride by reaction of chlorine and diketene. The process has a throughput which is from 5 to 750 kg of product per liter reaction volume hour, which means the process achieves a large plant scale throughput of reactants. A solution of chlorine dissolved in an inert solvent and a solution of diketene dissolved in an inert solvent are introduced simultaneously in a continuous current into a tube reactor in such a way that the two solvents immediately mix homogeneously and a turbulent flow develops. The turbulent flow in the tube reactor has a Reynolds number of at least 2,500. None of the reactants or components are used in gaseous form in the reaction, and no gaseous phase forms during the reaction. The mole ratio of chlorine to diketene is between 0.9 to 1 and 1.2 to 1. The same inert solvent can be used in both the chlorine solution and the diketene solution. Preferably a chlorinated hydrocarbon is used as the inert solvent. Preferably both the diketene and chlorine are each used in the form of a 1 to 15 percent by weight solution. Preferably a temperature which lies below the boiling point of the solvent is maintained in the reaction tube. |
