Abstract (en)
[origin: WO2015114034A1] 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.
