    Abstract: Chloralkylammonium chlorides are prepared by treating a mixture of an alkanolamine (40-86% by weight) and water at elevated temperature e.g. between 150 and 180 DEG C., and pressure in the presence of not more than 40%, based on the reaction mixture, of hydrogen chloride. Ethanolamine, di- and triethanolamines, isopropanolamine, 2-dimethylaminoethanol, 2-methylaminocyclohexanol, 2-phenylethanolamine, 3 - aminopropanol, 4 - aminobutanol and 4-aminocyclohexanol are specified and the reaction may be batchwise or continuous. A dehydration catalyst such as sulphuric or phosphoric acid, zinc chloride or aluminium phosphate may be included. Chloralkylamines may be obtained by the addition of a base. Specification 468,387 is referred to.
