Uses
Pesticide field: Diisopropyl malonate is an intermediate for the fungicide isoprothiolane (the correct name for the fungicide for controlling rice blast, instead of "rice blast" which is not accurate). It is used in agricultural production to synthesize related pesticides for preventing and controlling pests and diseases.
Pharmaceutical field: It is an important pharmaceutical intermediate and can be used to synthesize drugs such as Malotilate (the correct spelling of the drug name).
Organic synthesis field: It can be used to synthesize organic compounds such as 3-substituted coumarins, 2-carbonyl isopropoxy-3-hydroxyquinoxaline di-N-oxide.
Preparation method
Sodium malonate, benzene and isopropanol can be added to the reaction kettle, sulfuric acid is added dropwise at 60-70℃ for esterification reaction for 3-4h, the crude product is cooled and pumped into the washing kettle for water washing and alkali washing, the feed liquid is separated in the separator, and then the product is obtained by desolventization and distillation.
