Description

technical field [0001] The invention relates to a compound synthesis device, in particular to a production device of diisopropyl-S-benzyl sulfurized phosphoric acid ester. Background technique [0002] Diisopropyl-S-benzyl sulfophosphate is a systemic fungicide with good systemic fungicide. Absorbed by plant roots and leaf sheaths under the water surface, and dispersed to various parts of the plant. It is mainly used to prevent early and late rice panicle blast. It has remarkable effects on rice sclerotinia, sclerotinia, sheath blight, and planthopper control. This product also has lodging resistance. Most of the existing production devices are relatively complicated. Diisopropyl-S-benzyl phosphorothioate is used as a fungicide. The pros and cons of the production devices have important economic significance for improving product quality and reducing the content of by-products. Contents of the invention [0003] The object of the present invention is to provide the produ...
