ABSTRACT:
This invention relates to a process for separating methoxyisopropylamine and particularly to an improvement in the process for the recovery of methoxyisopropylamine from the reaction of methoxyisopropanol with ammonia under amination conditions. In this process water is produced as a byproduct and in the separation process an azeotrope is formed which comprises about 14% water and 86% methoxyisopropylamine at atmospheric pressure. The process for enhancing separation of the azeotrope comprises contacting the azeotrope of methoxyisopropylamine and water with diisopropylamine in sufficient amount to form the azeotrope of water and diisopropylamine and separating the azeotrope from the other materials in a distillation column. The overheads in this column is charged to a decanter where water is removed as a bottoms phase and the diisopropylamine as the upper phase and returned as reflux to the distillation volumn. The water free crude methoxyisopropylamine is then charged to another column and the methoxyisopropylamine recovered as an overhead.
