- 1 - HOE 91/F 901 Abstract of the disclosure Process for the preparation of dialkylaminopropanediol The novel process is based on the reaction of a dialkyl- amine, 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 tem- perature of 20 to 80°C, the dialkylamine being employed in an amount of at least 2.5 mol per mole of monohalopro- panediol. Using the novel process, a high space-time yield and also a high chemical yield of virtually pure dialkylaminopropanediol are obtained.
