Latest Patents

Tomio Yanai holds a patent for a method of preparing a highly pure monoalkylphosphine. This method involves reacting phosphine and an alkene in the presence of an anhydrous alkanesulfonic acid as a catalyst within a solvent that has a boiling point higher than that of the produced monoalkylphosphine. The process includes removing the catalyst, which is a sulfur atom-containing compound, by bringing the resulting monoalkylphosphine into contact with an alkali solution. Furthermore, the reaction solution is treated with alkali metal hydrides or alkaline earth metal hydrides to eliminate any residual moisture. The final product is isolated through distillation and purified by passing it through a layer of active carbon to remove impurities.
