Abstract

Alkanols are oxyalkylated by a process in which the reaction is carried out using a heterogeneous basic catalyst which is selected from basic aluminates, and the compounds prepared thereby are used as carrier oils in fuel additives or as nonionic surfactants in detergents or cleaning agents.
