Physical and Chemical Properties | This product is colorless liquid, B. p.116 ℃/400Pa, insoluble in water, soluble in most organic solvents. |
Use | 2, 3-dichlorobutanedioic acid Diethyl ester is an intermediate of the herbicide imidazolinic acid. |
production method | the preparation method is to add diethyl maleate and dichloroethane in a reaction kettle, and add chlorine gas under stirring, after about 5 hours, compressed air is introduced to drive off the remaining chlorine gas, and then the temperature is raised to 90-100 ° C. To distill dichloroethane, and the residue of the kettle is diethyl 2, 3-dichlorobutanedioic acid. |
