Abstract: Iminodibenzyl carbonyl chloride is one of the most important Pharmaceutical-Intermediate of the Carbamazepine production and the requirement grow up huge and quickly. The Carbonic dichloride and the Trichloromethyl carbonate are two commonly used acylating reagent to product the Iminodibenzyl carbonyl chloride. We determined the better production way following the fundament of advanced technology, reliable process, rational economy and optimal system, and choose the Carbonic dichloride as the acylating reagent. Then, the design of annual output 400 ton Iminodibenzyl carbonyl chloride was carried on according to the definite technological process:
(1)Complete the mass balance based on the produce of 400 ton I minodibenzyl carbonyl chloride.
(2)Complete the energy balance about the whole technology.
(3)Select the main equipments based on the mass balance.
(4)Correct the heat-transfer area of equipments based on the energy balance.
(5)Determine the proposal about how to deal with the waste gas.
