Patent

CA 2157825

The invention relates to a process for the preparation of 1,1,3-trialkoxypropane by acid-catalysed reaction of acrolein with a C1 to C6 alcohol, which can be carried out well on a large scale and leads to a higher selectivity. According to the invention the process comprises (a) the reaction, in the presence of a solid acid catalyst which is insoluble in the reaction mixture, (b) a partial neutralisation of the reaction mixture, using an amine or basic ion exchanger and (c) specific working up by distillation of the reaction mixture and recirculation of fractions containing useful materials; aqueous fractions containing recyclable useful materials are largely dehydrated by pervaporation prior to being recirculated.
