and Summary The acid chlorides of methyl hydrogen glutarate and methyl hydrogen adipate were allowed to react with various primary fatty amines. The resulting amido esters were converted into the corresponding amino diamides by sodium catalyzed reaction with N,N‐dimethylaminoalkylamines. The desired sulfobetaines were obtained by reaction of the resulting N‐alkyl‐N′‐(1,1‐dimethylaminoalkyl) glutaramides and adipamides with 1,3‐propanesultone. The compouds possess the same excellent lime soap dispersing ability, water solubility, calcium ion stability, and detergency properties as the analogous succinamide derivatives previous reported. This indicates that the spacing between the two amido groups or that between the quaternary nitrogen atom and the nearest amido group does not affect surface active properties.
