| titleOfInvention | A kind of chlorinated hydrolysis production method in ethylmaltol production |
| abstract | The present invention relates to the chlorinated hydrolysis production method during a kind of ethylmaltol produces, comprise the following steps: after a. chlorination reaction terminates, the material circulating pump in chlorination tank is sent into distillation column; B. ON cycle pump, open steam valve, carry out Rapid Circulation heat exchange with plate type heat exchanger, make material be brought rapidly up Distillation recovery methanol, the steam off valve when temperature rises to 90 DEG C; C. the methanol feeding methanol dosage bunker of Distillation recovery is reused, and in distillation column, the material after distillation is with being pumped into hydrolysis kettle, keeps between hydrolysis kettle temperature 90 ~ 95 DEG C, and be hydrolyzed reaction. The present invention realizes the seriality of production operation, and the production cycle is greatly shortened, and is shortened to 10 hours by original 16 hours, and operational stability is good and conversion ratio improves 6%, and by-product significantly reduces, and improves ethylmaltol quality and yield. |
