Process for preparing acid Esters alcohil - N - n, n ', n' - - - polioxialcohil diaminoalcohilen fatty '.

摘要

Method for producing Quaternary Ester of N - alcohil - n, N, N - polioxialcohil - ~ C, W - diaminoalcohilen - Fatty Acids of formula (i), in which, N, M and P are 0 - 1 - 1, 2, 11, 2 and 1 - 5, respectively it is a; anion; R is alcohilo or alquenilo - C C - is alcohilo; R, R is alcohilo or Quenilo C -; and X and y are Hydrogen or Methyl.Consists in the Esterification reaction of a compound of formula (ii) with an Acid COOH r in the formula, All the symbols have the same meaning as in formula (i), followed by quaternization of the product formed with a Reagent alcohilante introduces the radical R, as The same or r in the formula (i).The Esterification reaction is carried out with Warming temperatures close to 170 C. these compounds have applications as clarifying agents and Smoothing clothes, towels and underwear.
