Claims9
A phosphorus-containing compound, comprising a structure represented by formula (I):
- wherein R1 and R2 are each independently a hydrogen atom, an alkyl group of 1 to 6 carbon atoms, a trifluoromethyl group, an unsubstituted phenyl group, a substituted phenyl group, an unsubstituted naphthyl group or a substituted naphthyl group, wherein R1 and R2 are not the hydrogen at the same time, and the hydrogen on the phenyl group of the substituted phenyl group is substituted by a monovalent organic group, the hydrogen on the naphthyl group of the substituted naphthyl group is substituted by a monovalent organic group, and the monovalent organic group is the alkyl group of 1 to 6 carbon atoms, X and Y are each independently —OH or a group represented by formula (MA):
- wherein R3 is the hydrogen atom or the alkyl group of 1 to 6 carbon atoms.
A manufacturing method for a phosphorus-containing compound, comprising:
- synthesizing a hydroxyl group-containing compound, wherein an organic phosphorus-containing compound represented by formula (i) is reacted with a carbonyl group-containing compound represented by formula (ii) to obtain a hydroxyl group-containing compound represented by formula (iii):
- and
- performing an acid-catalyzed reaction, wherein the hydroxyl group-containing compound represented by formula (iii) is reacted with benzenediol at a catalysis of an acid catalyst to obtain a phosphorus-containing compound represented by formula (I—OH):
