超声作用下合成氯代二异丙基膦

Synthesis of chlorodiisopropylphosphine under ultrasound irradiation

以镁、氯代异丙烷和三氯化膦为主要原料,四氢呋喃为溶剂利用超声波合成标题化合物,产率可达80.1%,经分馏纯度达96%。该方法反应液澄清,副产物无水氯化镁容易处理,降低了对环境的污染。

Chlorodiisopropylphosphine was synthesized from magnesium, isopropyl chloride and phosphorus trichloride in the presence of tetrahydrofuran used as the solvent. The reactor was irradiated by ultrasound. The product yield was increased to 80.1% with purity reaching 96% after fractionation. The improvement was that the solution formed during the synthesis was clear and it was easy to dispose of the residue compared with other synthetic methods. This process was a cleaner one.
