stable concentrated solution of glycidyltrimethylamnoniumchloride and method for preparation of stable concentrated solutions of glycidyltrimethylammoniumchloride

摘要

Stable concentrated aqueous solutions of glycidyltrimethylammonium chloride are provided which contain the monohydrate of glycidyltrimethylammonium chloride in a concentration of 90% to saturation, said solutions after dilution with water to a content of 25% glycidyltrimethylammonium chloride showing a pH of less than 12.5. Furthermore a process is provided for preparing stable concentrated solutions of glycidyltrimethylammonium chloride, wherein anhydrous glycidyltrimethylammonium chloride is mixed with an excess of water over the amount necessary for forming the desired solution, whereafter the excess of water is evaporated under reduced pressure. Also the invention provides the monohydrate of glycidyltrimethylammonium chloride as a novel substance.
