ABSTRACT:
The invention relates to a process for preparing highly concentrated, free-flowing and pumpable, aqueous solutions of betaines by quaternization of compounds containing tertiary amine nitrogen with omega-halocarboxylic acids by known processes, which is characterized in that a) 30-100 equivalent-%, based on the amount of omega-halocarboxylic acid used, of Mg(OH).sub.2 and/or Ca(OH).sub.2 and b) 0-70 equivalent-%, based on the amount of omega-halocarboxylic acid used, of one or more NaOH, KOH and NH.sub.4 OH are added to the reaction mixture before or during the quaternization reaction.
