The reaction of an organic monohydroxy compound with a monomeric epoxide is catalyzed by insoluble, polymeric composition having tetraalkyl phosphonium alkoxide, aryloxide or hydroxide containing pendant groups. These groups have the structure ##STR1## wherein n is an integer from 1 to 3, preferably 3, m is an integer from 1-6, preferably 3-6, R is an alkyl group of from 1 to 6 C atoms, R' is H, an alkyl, CN, or other group inert to reaction with phosphonium halides, alkoxides or the phosphonium salt resins or in some instances to organolithium reagents and X is an alkoxy, cycloalkoxy or aryloxy group, or an OH group. The above catalysts are readily removed from the reaction mixture because of their insolubility. They are particularly useful for making monoethers of the structure A(OA').sub.b OH where A is the nonhydroxyl residue of the monohydroxy compound and A' is the nonhydroxy residue of an epoxide monomer, and b is an integer of from 1 to about 20 with b = 1-5 preferred.
一种不溶性聚合物组成催化剂,其含有四烷基膦醇酸盐、芳基醇酸盐或羟基官能团的悬挂基团,用于有机单羟基化合物与单体环氧化合物的反应。这些基团的结构为##STR1##其中n为1至3的整数,优选为3,m为1至6的整数,优选为3至6,R为1至6个碳原子的烷基,R'为H、烷基、CN或其他对
膦酸盐、醇酸盐或膦盐
树脂反应惰性的基团,在某些情况下也对
有机锂试剂反应惰性,X为烷氧基、环烷氧基、芳基氧基或羟基。由于催化剂不溶于反应混合物,因此可以轻易地从反应混合物中去除。它们特别适用于制备结构为A(OA')bOH的单醚,其中A为单羟基化合物的非羟基残基,A'为环氧单体的非羟基残基,b为1至约20的整数,优选b = 1-5。
