Bis-hydroxy diamides and methods therefor
Abstract
Abstract Novel bis-hydroxy diamides having the formula: ##STR1## where R is an alkyl or aryl moiety having from 3 to 10 carbon atoms and where x ranges from 1 to 6 may be produced by reacting dicarboxylic acids with polyethylene glycol monoamines. Suitable dicarboxylic acids include adipic acid, terephthalic acid, isophthalic acid, t-butyl isophthalic acid, 1,1,3-trimethyl-5-carboxy-3-(p-carboxyphenyl)indane, and mixtures thereof. Suitable monoamines include diethylene glycol monoamine, also known as Diglycolamine® amine (DGA); triethylene glycol monoamine (TEGMA) and tetraethylene glycol monoamine (T 4 EGMA), among others. The resulting bis-hydroxy diamides are useful to make hydroxy-terminated polyamides and as fuel additive corrosion inhibitors. The diamides have unusual solubility properties.
