Способ относится к технологии получения алкандиолов, находящих широкое применение в производстве пенопластов в качестве антифризов, растворителей и пластификаторов. Цель изобретения - упрощение технологического процесса и снижение энергозатрат. Для этого гидратацию окисей алкенов проводят при 95 - 150°С и давлении в присутствии катализатора - кислородного соединения бора общей формулы RnBxOy, где R - водород, натрий, калий; n = 1 - 3; x = 1 - 4; y = 2 - 7, в мольном соотношении окись алкена: вода : кислородное соединение бора 1 : 2 - 22 : 0,00006 - 0,0016, преимущественно 1 : 4 - 15 : 0,00012 - 0,00018, с последующей отпаркой окиси алкена и воды и их возвратом в технологический процесс.The method relates to the technology of alkanediol, which are widely used in the production of foams as antifreezes, solvents and plasticizers. The purpose of the invention is to simplify the process and reduce energy costs. To this end, the hydration of alkene oxides is carried out at 95-150 ° C and pressure in the presence of a catalyst — an oxygen boron compound of the general formula R n B x O y , where R is hydrogen, sodium, potassium; n = 1 - 3; x = 1 - 4; y = 2 - 7, in a molar ratio alkene oxide: water: oxygen boron compound 1: 2 - 22: 0.00006 - 0.0016, mostly 1: 4 - 15: 0.00012 - 0.00018, followed by stripping the oxide alkene and water and their return to the process.
