Procedure

One-quarter mole of alpha-bromoethyltrichlorosilane is dissolved in 200 ml. of dry hexane and sparged rapidly with nitrogen. 0.85 moles of the beta-methoxyethanol is added slowly and the resulting mixture is stirred until the HCl evolution ceases. Distillation of the residue yields alpha-bromoethyltris(beta-methoxyethoxy)silane. This produce (0.2 moles) is heated with 0.2 moles of the diacetate ester of dodecyldiethanolamine at 135° C. for 16 hours to yield the desired quaternary ammonium salt.
