초록 ▼

A process for the preparation of phenolic hydroxy ethers whereby an aromatic hydroxyl-containing compound is reacted with a vicinal epoxy-containing compound in the presence of a phosphonium salt of an acid, ester or acid ester of an element selected from carbon or phosphorus, and to precatalyzed ep

대표청구항 ▼

In a process for preparing phenolic hydroxy ethers which comprises reacting a polyhydric phenol with a polyepoxide having more than one 1,2-epoxy group, the improvement comprising employing as the catalyst therefor, a phosphonium salt of an acid, ester or acid ester of the element carbon represented by the general formula R1+ │ R4－P－R2Xm │ R3m wherein R1, R2, R3 and R4 are independently selected from the group consisting of aliphatic hydrocarbon radicals containing from about 1 to about 20 carbon atoms, aromatic hydrocarbon radicals, alkyl substituted aromatic hydrocarbon radicals and radicals represented by the formula -R5Y wherein R5 is an aliphatic hydrocarbon radical having from about 1 to about 20 carbon atoms and Y is a member selected from the group consisting of Cl, Br, I, and NO2, and wherein X is the anion portion of an acid, ester or acid ester of the element carbon and wherein m is the valence of the anion X.
