Abstract
A new class of useful gasoline additives is prepared via two consecutive reactions including: (1) amidation of water-soluble hydrophilic, low molecular weight triamine with alkyl acetate at an elevated temperature under N.sub.2 pressure to prepare a symmetrical triamide; and (2) alkoxylation of the triamides with 1,2-epoxyalkane to prepare poly(oxyalkylene)triamide alkoxylate of three telechelic hydroxy groups, having the general formula: ##STR1## wherein x, y and z are from 1 to 20, R is poly(oxyalkylene) of a molecular weight from 72 to 1000, and R' is an alkyl having a carbon number from 2 to 18.
