- Investigation on the acylation of heterocyclic alcoholate anions with O,O-dialkyl phosphorochloridothioate in water solvent
-
The acylation of some heterocyclic alcoholate anions with O,O-dialkyl phosphorochloridothioate has been investigated. Higher yields and fewer byproducts were achieved in water at 50 °C by employing an effective phase-transfer catalyst (PTC) (benzyl triethylammonium chloride [BTEAC]), acylation catalyst (AC) (4-dimethylaminopyridine), and surfactant (sodium dodecyl sulfate), under weakly basic (pH 9.5～10) conditions. This reaction can also be applied to synthesize other insecticides with excellent yields.

- Pesticide compositions and method
-
Toxicant, especially pesticide compositions, having lowered dermal toxicity are provided. The compositions include a lipophilic-pesticide, a nonionic surfactant and a dry inert diluent carrier. Methods for reducing the dermal toxicity of lipophilic toxicants, especially pesticides are provided, as well as methods for controlling insect pests using the disclosed compositions.
