PHOSPHONIUM SALT, CATALYST FOR POLYMERIZATION OF ALKYLENE OXIDE COMPOUND, AND PROCESS FOR PRODUCTION OF POLY(ALKYLENE OXIDE)

摘要

Disclosed is a phosphonium salt compound which can be synthesized readily and is useful as a basic catalyst. The phosphonium salt compound is represented by the general formula (1). (1) wherein Qn- represents an anion of an n-valent active hydrogen compound which is produced by removing n protons from an active hydrogen compound having at least one carbon atom and also having up to 8 active hydrogen atoms on an oxygen atom or a nitrogen atom; a, b and c independently represent a positive integer of 3 or smaller or 0, provided that all of a, b and c in a molecule are not 0; and R's independently represent a hydrocarbon group having 1 to 10 carbon atoms, and two R's on one nitrogen atom may together form a cyclic structure. ® KIPO & WIPO 2009
