Title (EN) CONTROLLED POLYALKOXYLATION METHOD OF FATTY AMINES
(FR) PROCÉDÉ DE POLYALCOXYLATION CONTRÔLÉE D'AMINES GRASSES
Abstract: front page image
(EN)The present invention provides methods of preparing quaternary fatty ammonium polyalkoxylates having 2 (nearly) symmetrical alkoxylate chains in a one-pot reaction under anhydrous conditions comprising the steps of (i) alkoxylating a primary fatty amine under anhydrous conditions in the absence of a catalyst using a suitable alkoxylation agent to obtain a (nearly) symmetrical tertiary fatty amine Ν,Ν-alkoxylate, (ii) extending the N,N-alkoxylate groups by reacting the (nearly) symmetrical tertiary fatty amine Ν,Ν-alkoxylate with a suitable alkoxylation agent in the presence of a basic catalyst (under controlled temperature and pressure conditions) to obtain a (nearly) symmetrical tertiary fatty amine N,N- polyalkoxylate, and (iii) reacting the (nearly) symmetrical tertiary fatty amine N,N- polyalkoxylate with a suitable alkoxylation agent under neutral to acidic conditions to obtain the desired quaternary fatty ammonium polyalkoxylate.
(FR)Cette invention concerne des procédés de préparation de polyalcoxylates d'ammonium quaternaire gras ayant 2 chaînes alcoxylate (presque) symétriques dans une réaction monotope et dans des conditions anhydres, comprenant les étapes de (i) alcoxylation d'une amine primaire grasse dans des conditions anhydres en l'absence de catalyseur à l'aide d'un agent d'alcoxylation convenable pour obtenir un N,N-alcoxylate d'amine tertiaire grasse (presque) symétrique, (ii) allongement des groupes N.N-alcoxylate par réaction du N,N-alcoxylate d'amine tertiaire grasse (presque) symétrique avec un agent d'alcoxylation convenable en présence d'un catalyseur basique (dans des conditions de température et de pression contrôlées) pour obtenir un N,N-polyalcoxylate d'amine tertiaire grasse (presque) symétrique , et (iii) réaction du N,N-polyalcoxylate d'amine tertiaire grasse (presque) symétrique avec un agent d'alcoxylation convenable dans des conditions neutres à acides pour obtenir le polyalcoxylate d'ammonium quaternaire gras recherché.
