Abstract: N-Alkylpiperidines or N-alkylpyrrolidines are obtained by hydrogenating a corresponding N-alkyldicarboxylic acid imide over a fixed catalyst by first working to only partial conversion, for example of about 50%, and distilling off the required product together with water from the partially converted mixture, where appropriate with recycling of the unconverted remainder.

Abstract: Prepn. of dipropylene triamine and tripropylene tetramine comprises condensing 1,2- or pref. 1,3-propylene diamine at 50-250 degrees C, pref. in presence of H2 and opt. with addn. of NH3. A Gp. VIII metal-contg. catalyst is used, including noble metals, and NH3 is produced during reaction. Higher polycondensates are decomposed to the dimers and trimers. At 25-200 bars H2 pressure and 160-200 degrees C conversions of ca 60% and sometimes ca 100% are obtd. for reaction times of 1-4 hrs. Good specificity for the dimer can be obtd. Prods. can be sepd. easily by distillation; very little prodn. of cyclic, branched or partially deaminated prods. occurs.

Abstract: In the prodn. of aminopropyl ethers (I) of polyhydric alcohols (II) by addn. of excess CH2:CHCN to (II) in the presence of alkaline catalysts (III) and hydrogenation of the cyanoethyl ether (IV) formed, after removing the excess CH2:CHCN, the mixt. is treated with NH3 before hydrogenation. (I) are used in the prodn. of synthetic resins by reaction with epoxides or dicarboxylic acids. Under suitable conditions, NH3 reacts with CH2:CHCN without causing aminolysis of (IV). On hydrogeneration, the aminonitriles are converted mainly to H2N(CH2)3 NH2, which is a valuable by-prod. Better results are obtd. if a small amt. of an aprotic polar solvent is added before the NH3. E.g. HO(CH2)4OH was reacted with CH2:CHCN is the presence of C6H5CH2NMe3OH, treated with N-methylpyrrolidone and NH3 and hydrogenated. No loss of catalytic activity or increase in the yield of prods. with a higher b.pt. than H2N(CH2)3O(CH2)4O(CH2)3NH2 occurred in 5 months prodn.

Abstract: Catalyst (I) for the hydrogenation of a carboxylic ester to the alcohol corresp. to the carboxylic acid is based on opt. supported Cu, Cr and opt. an alkali metal and other elements. At least one alkaline earth metal is added later. (I) is obtd. by mixing Cu and/or Co cpds. (sic) with alkali and/or alkaline earth cpd(s). in solid or dissolved form and opt. together with a support and pptn. from the soln. if necessary, so that a solid mixt. is formed. The mixt. is calcined at 100-500 degrees C and the surface is treated with an alkaline earth metal. (I) is then activated by redn. (I) is esp. used in the redn. of liquid or solid satd. or unsatd. dicarbocylic esters of diols to the corresp. satd. diols, e.g. the adipate (II) of hexandiol (III), esp. mixts. of esters obtd. in the oxidn. of hydrocarbons. E.g. a calcined mixt. of 66 (wt)% Cu oxide and 3% Na oxide was sprayed with Ca nitrate soln., dried and calcined, giving a catalyst contg. 3-3.6% ca Wrt Cu. This was used in the hydrogenation of (II), giving a 98.5-99% yield of (III).
