Achievements


The achievement of "Development and Application of Key Technologies for the Production of Phenylphosphine Derivatives" is awarded the second prize of Henan Science and Technology Invention Award in 2019. A new process for selectively cutting carbon phosphine bonds to produce a series of phenyl phosphine derivatives by the "one-pot method" was developed, and the influence of the catalyst choice on yield during the reaction of the series of phenyl phosphine derivatives had been thoroughly studied. The key technical problems of poor stability of organic phosphine compounds and difficulty in industrialization had been solved, with significant economic and social benefits.
