FIELD: organic chemistry. SUBSTANCE: monoalkyl ethers of propylene glycol (1-alkoxy-2-propanol) are prepared by interaction of C1-C4-aliphatic alcohols and propylene oxide, the process is carried out in the presence of alkaline catalyst. Additionally 2-alkoxy-propanol-1 is present in reaction mixture, its quantity being 0.5-3.0 mass %. Selectivity of proposed method in respect with 1-alkoxy-2-propanol is increased up to 86.0-94.0 mol % caused by decreased formation of isomer and alkyl ethers of di- and tripropylene glycols. EFFECT: improved efficiency of the method.
