摘要 |
Synthetic detergents of the ampholytic betaine type are provided, having a 2-hydroxy propylene ether group attached to the nitrogen atom of the betaine; the 2-hydroxy propylene ether group optionally can include a plurality of oxyalkylene units. The process for preparing these betaines easily and inexpensively involves reaction of an alcohol or hydroxy compound with epichlorohydrin to form the corresponding chloroglyceryl ether, which can be aminated and quaternized either in two stages, by reaction of a dialkyl amine and a straight or branched halogenated carboxylic acid, or in one stage by reaction of an amino acid. Detergent compositions containing these betaines are also provided. |
