METHOD FOR PRODUCING ORGANOPHOSPHORUS COMPOUND

PROBLEM TO BE SOLVED: To provide a method for producing an organophosphorus compound which has excellent energy efficiency without containing a halogenated alkyl or a by-product derived from a halogenated alkyl. SOLUTION: There is provided a method for producing an organophosphorus compound by reacting a trivalent organophosphorus compound represented by the following general formula (1) in the presence of a super strong acid and/or at least one acid catalyst containing a solid superstrong acid catalyst to generate a pentavalent organophosphorus compound represented by the following general formula. (where Z1 represents OR2 or R2; Z2 represents OR3 or R3; R1, R2 and R3 represent an alkyl group, an alkenyl group or the like; when R2 and R3 are an alkyl group or the like, R2 and R3 may be bonded to each other to form a cyclic structure; and R1 may be a hydrogen atom.)
