Abstract

A process where alkylpolyalkylene glycol ethers (IV) are reacted with an organic halide (V) in the presence of from 80 to 100% purity, solid, particulate alkali metal hydroxide at a V:IV molar ratio in the range from 1.5:1 to 2:1 and an alkali metal hydroxide:(IV) molar ratio in the range from 1.5:1 to 2:1, at from 60 to 140 DEG C.
