FIELD: chemical industry; methods of production of the polyethers of the aliphatic alcohol. ^ SUBSTANCE: the invention is pertaining to the method of production of the polyethers of the aliphatic alcohol by alkoxylation of the organic compounds by alkoxylation of the organic compounds with the alkoxylating agent, which is selected from the mono- or multipurpose epoxides having from 2 up to 30 atoms of carbon and the mono- or multipurpose polyesterpolyols having the molecular mass about 600 g/mole, or their mixtures in the presence of the catalytic system, which includes the organometallic framework material containing the pores and, at least, one ion of the metal, and, at least, one bidentate organic compound, which is coupled with the indicated ion of the metal by the coordination bond. At that the ion of the metal is selected from ions of the elements of the groups Ia, IIa, IIIa, IVa up to VIIIa and Ib up to VIb of the Periodic system, and the bidentate organic compound is selected among the substituted or un substituted aromatic polycarboxylic acids which may contain one or several atomic nuclei and the substituted or unsubstituted aromatic polycarboxylic acids, which contain, at least, one heteroatom and which may have one or several kernels. The given method allows to produce the polyethers of the aliphatic alcohols having the small amounts of the impurities, in particular, of the low molecular substances having the intensive odor and which does not include the complex stages of refining of the source materials and-or the intermediate products. The produced polyethers of the aliphatic alcohols are used for production of the polyurethane by interaction of such polyether of the aliphatic alcohol, at least, with one isocyanate. ^ EFFECT: the invention allows to produce the polyethers of the aliphatic alcohols having the small amounts of the impurities, the low molecular substances with the intensive odor, which does not include the complex stages of refining of the source materials and-or the intermediate products. ^ 2 cl, 4 ex, 2 dwg |
