| titleOfInvention | A kind of method reclaiming dichloromethane in chlorine ketone mother solution |
| abstract | The present invention relates to a kind of based on the process reclaiming dichloromethane in the chlorine ketone mother solution being thermally integrated, it is characterized in that first material enters heat exchanger 1 to carry out preheating for the first time with high-pressure tower overhead vapours, rear entrance heat exchanger 2 and tower reactor still liquid carry out second time and preheat, subsequently into high-pressure tower, tower top obtains dichloromethane steam after treatment；Dichloromethane steam is got off by total condensation after charging heat exchange, and the rear phase separator that enters carries out stratification, the light phase high-pressure tower that is recycled back into, and heavy phase extraction enters dichloromethane storage tank 5；Chlorine ketone mother solution after dichloromethane removing, from high-pressure tower tower reactor extraction, carries out Temperature fall after heat exchange, finally realizes the recovery of chlorine ketone；In the product obtained, dichloromethane purity is more than 99.95%, and the dichloromethane response rate is more than 99.5%, and the chlorine ketone response rate is more than 99.95%. |
