The catalytic alkylation of primary and secondary amino groups in linear polyamines using an 'activated' copper catalyst.

Catalytic alkylation of primary and secondary amino groups in linear

This invention relates to amphoteric surface-active agents which have extremely powerful inhibitory action against Gram positive bacteria and which are substantially free from metal halide, and, particularly, sodium chloride. These compounds have the general structure: ##EQU1## wherein R is a straight chain alkyl having from 6 to 16 carbon atoms, R' is a lower alkyl, and M is either hydrogen, an alkali metal or an alkylolamine.

Amphoteric surface-active agents

A surface-active composition consisting essentially of (a) a compound having the structure: ##EQU1## wherein R is a member of the group consisting of C.sub.2 H.sub.4 and C.sub.3 H.sub.6 and X is a member of the group consisting of OH and NH.sub.2, and (b) another surface-active agent selected from the group consisting of anionic, cationic and non-ionic surface active agents.
