Abstract
A process is provided for preparing quaternary ammonium compounds which contain both cationic and nonionic hydrophilic groups in the molecule. Alkylene oxide is reacted with aliphatic alcohol in the presence of an alkali catalyst at an elevated temperature; the resulting alkoxyglycol alcohol or ether is reacted with epichlorohydrin, producing the corresponding chloroglyceryl or chlorohydroxypropylene ether; and this is then reacted with a secondary amine to produce the quaternary ammonium compound.
