## Abstract Linear and heavy alkyl benzene (HAB) were sulfonated with fuming sulfuric acid (oleum) and the sulfonated products were esterified with tri and poly ethanolamine (__d__ = 4 and 6). The prepared three esters from each series were quaternized with __n__‐butyl bromide. The resulted six qua
