摘要： 2,2'-Dimorpholinodiethyl ether is produced by reacting diethylene glycol with ammonia under pressure at elevated temperature in the presence of hydrogen. The active hydrogenation catalyst, before reduction with hydrogen, contains 20-85 wt.% alumina, zirconium dioxide, titanium dioxide and/or silica, 1-70 wt.% copper oxide (CuO), less than 20 wt.% nickel oxide with respect to CuO and 0-50 wt.% other metal oxide(s). In the production of 2,2'-dimorpholinodiethyl ether (DMDEE) by reacting diethylene glycol with ammonia under pressure at elevated temperature in the presence of hydrogen and a hydrogenation catalyst, the active catalyst, before reduction with hydrogen, contains 20-85 wt.% aluminum oxide (Al2O3), zirconium dioxide (ZrO2), titanium dioxide (TiO2) and/or silica (SiO2), 1-70 wt.% copper oxide (expressed as CuO), 0-50 wt.% magnesium, chromium, zinc, barium and/or calcium oxide (expressed as MgO, Cr2O3, ZnO, BaO and CaO) and less than 20 wt.% nickel oxide (expressed as NiO) with respect to CuO.

摘要： Gas phase racemisation of an optically active amine uses a hydrogenation or dehydrogenation catalyst in the presence of hydrogen at an elevated temperature. Production of racemic amines (I) comprises racemisation of a corresponding optically active amine by reaction with a hydrogenation or dehydrogenation catalyst in the presence of hydrogen at an elevated temperature in the gas phase. R , R = different and are alkyl, cycloalkyl, aralkyl, aryl, heteroaryl or heterocyclyl, all optionally substituted by Q; provided that R and R = different; R = H or alkyl, cycloalkyl, aralkyl, aryl, heteroaryl or heterocyclyl, all optionally substituted by Q; Q = alkyl, cycloalkyl, alkoxy, aryloxy, NH2, NH(alkyl) or N(alkyl)2.

摘要： The invention concerns a process for preparing tetrahydrofuran by reacting 1,4butene diol diethers of formulae (I) -RO-CH2-CH=CH-CH2-OR and/or (II) -RO-CH2-CH2=CH-CH2-OR, in which the R groups can be identical or different and stand for C1-C15 alkyl or cycloalkyl groups, C6-C12 aryl groups or C7-C15 aralkyl groups, with water and hydrogen at temperatures of between 20 and 300 ~C and a pressure of between 1 and 300 bar in the presence of catalysts or catalyst combinations which both contain components which can hydrogenate and comprise acid or basic centres. The invention further concerns a novel process for preparing the 1,4-butene diol diethers of formula (I) by metathesis.
