摘要

N,N'-diacyldiethylene bishydroxy alkyltriamine methyl sulfate of formula (I) useful as a softening agent for fiber is prepd. by: reacting 2 mole fattic acid and 1 mole diethylene triamine and then adding and reacting with 1 mole water to prepare N,N'-diacyl diethylene triamine of formula (II); reacting with epoxide, e.g. ethylene oxide or propylene oxide; then reacting with dimethyl sulfate. In the formulas, R is C12-C20 alkyl; R1 is H or methyl. The obtd. cpd. has excellent flexibility.
