METHOD OF SYNTHESIS OF ETHER Russian patent published in 2002 - IPC

FIELD: organic chemistry, chemical technology. SUBSTANCE: invention relates to a novel method of synthesis of ethers used as solvents, lubricant oils, gluing agents, resins and so on. Invention relates to synthesis of the ether of the general formula (XV) or the general formula (XVI) where R³³ and R³⁴ each means methyl, ethyl, n-propyl, isopropyl or hydrocarbon group containing atoms or ether oxygen in the main, side or in both chains that can be similar or different and also R³⁵, R³⁶, R³⁷ where each means hydrogen atom, methyl, ethyl, n-propyl or hydrocarbon group containing atoms of ether oxygen in the main, side or both chains that can be similar or different. Method involves the interaction of acetal or ketal of the general formula (XIV) with hydrogen in the presence of catalyst. The catalyst is taken among the hydrogenation catalyst and solid acidic catalyst or solid acidic catalyst exhibiting hydrogenating ability. EFFECT: improved method of synthesis. 3 cl, 2 dwg, 13 ex
