Abstract: The novel process is based on the reaction of a dialkylamine, preferably dimethylamine or diethylamine, with a monohalopropanediol, preferably monochloropropanediol, in the presence of water. The reaction is carried out in the presence of 25 to 70% by weight of water and at a temperature of from 20 to 80 DEG C, the dialkylamine being employed in an amount of at least 2.5 mol per mol of monohalopropanediol. The novel process allows a high space-time-yield and also a high chemical yield of virtually pure dialkylaminopropanediol to be obtained.
