DIISOPROPYL MALONATE - Upstream Downstream Industry
DIISOPROPYL MALONATE - Reference Information
| Use | diisopropyl malonate is a Disinfection by-product of isopropylthio-heterocyclic pentane. A disulfide pesticide, usually used as a fungicide in agriculture to control Rice planthopper and rice blast. diisopropyl malonate is an intermediate of the fungicide meilingling. used as pharmaceutical and pesticide intermediates pharmaceutical intermediates. |
| production method | the preparation method is to add sodium malonate, benzene and isopropanol in the reaction kettle, sulfuric acid was added dropwise at 60-70 ℃ for 3-4H. After the reaction, the crude diisopropyl malonate was cooled and drawn into a washing kettle to be washed with water and washed with alkali, and the liquid was separated in a separator, followed by desolvation and distillation to obtain a product. |
