CA 2375487

This invention relates to a composition, comprising: (I) an aromatic Mannich compound derived from: (A) a hydroxy containing aromatic compound having formula (A-1) wherein in Formula (A-1): Ar is an aromatic group; m is 1, 2 or 3; n is a number from 1 to about 4; with the proviso that the sum of m and n does not exceed the number of available positions on Ar that can be substituted; each R1 independently is a hydrocarbyl group of up to about 400 carbon atoms; and R2 is H, amino or carboxyl; (B) an aldehyde or ketone having formula (B-1) or a precursor thereof; wherein in Formula (B-1): R1 and R2 independently are H or hydrocarbyl groups having from 1 to about 18 carbon atoms; and R2 can also be a carbonyl-containing hydrocarbyl group having from 1 to about 18 carbon atoms; and (C) a mixture of water and an amine, said amine containing at least one primary or secondary amino group; and (II) alcohol. The invention also relates to a process for making the foregoing composition.

L'invention concerne une composition comprenant : (I) un composé Mannich aromatique dérivé de : (A) un composé aromatique contenant de l'hydroxy, correspondant à la formule A-1, dans laquelle Ar est un groupe aromatique ; m est 1, 2 ou 3 ; n est un nombre compris entre 1 et environ 4 ; sous réserve que la somme de m et de n ne dépasse pas le nombre de positions disponibles sur Ar qui peut être substitué ; chaque R?1¿ est indépendamment un groupe hydrocarbyle comprenant un maximum de 400 atomes de carbone environ ; et R?2¿ est H, amino ou carboxyle ; (B) un aldéhyde ou une cétone correspondant à la formule B-1 ci-dessous, ou un précurseur de ces derniers, dans laquelle R?1¿ et R?2¿ sont, chacun, H ou des groupes hydrocarbyle comprenant entre 1 et environ 18 atomes de carbone ; R?2¿ peut également être un groupe hydrocarbyle contenant du carbonyle, qui comprend entre 1 et environ 18 atomes de carbone ; et (C) un mélange d'eau et d'une amine, ladite amine contenant au moins un groupe amino primaire ou secondaire ; et (II) de l'alcool. L'invention concerne également un procédé de fabrication de ladite composition.
