FIELD: industrial organic synthesis.
SUBSTANCE: invention provides a process for production of alkylene glycols, which are useful as components for low-freezing, antiicing, hydraulic, and braking fluids as well as in production of solvents, plasticizers, for obtaining materials used in plastic industry, pesticides, lacquers, and paints. Process comprises hydration of alkylene oxide at elevated temperatures and pressure in displacement reactor in presence of catalytic system based on anion-exchange resins in salt form and organic or inorganic iodine compounds.
EFFECT: reduced catalyst swelling rate and increased selectivity of process.
