Abstract
Salts having the formula: Y--NH.sub.3.sup..sym..RCO.sub.2.sup..crclbar. I in which Y is a group of formula R.sup.1 XCH.sub.2 CH(OH)CH.sub.2 --, R and R.sup.1 are the same or different and each is a straight- or branched chain alkyl group having from 1 to 18 carbon atoms, a straight- or branched chain alkenyl group having from 2 to 18 atoms, a cycloalkyl group having from 4 to 12 ring atoms, an aryl group having 6-10 ring atoms, or an aralkyl group having from 7 to 10 carbon atoms; and X is O,CO.sub.2, NR.sup.2 or S and R.sup.2 is hydrogen, a straight- or branched chain alkyl group having from 1 to 18 carbon atoms or an alkenyl group having from 2 to 18 C atoms. These salts are useful as corrosion inhibitors.
