    Abstract: 1,167,412. The production of cyclopentylamine and n-pentylamine. BADISCHE ANILIN- & SODA-FABRIK A.G. 17 Feb., 1967 [19 Feb., 1966], No. 7684/67. Heading C2C. Cyclopentylamine and n-pentylamine are prepared by reacting a mixture, which contains mainly cyclopentanol and n-pentanol and which has been prepared by the hydrogenation of the by-products obtained from the air oxidation of cyclohexane after the removal of cyclohexanone and cyclohexanol, with 8 to 20 moles of ammonia per mole of alcohol at temperatures of 100‹ to 300‹ C. and at pressures of 10 to 500 atmospheres in the presence of a conventional hydrogenation catalyst to form a mixture of the corresponding amines, adding water and separating the n-pentylamine by azeotropic distillation. Suitably the reaction is carried out in the presence of hydrogen and using cobalt and/or nickel as catalyst and the starting mixture contains 50 to 80% w/w of n-pentanol and 10 to 14% w/w of cyclopentanol.

    Abstract: Catalysts for the production of diamines (see Division C2) comprise at least one of the metals silver, copper, iron, cobalt and nickel prepared by sintering the metal powder or by reducing the sintered metal oxide or hydroxide, carbonate, nitrate or nitrite before or after shaping. Examples employ sintered Co, (Co + Ni), and (Co + Cu) or Ni. The powdered metal is sintered in admixture with a carrier such as pumice, alumina, corundum, diatomaceous earth, silica gel, silicon carbide, silicates, porcelain or quartz. Promoters such as alkali metal compounds, alkaline earth metal compounds, titanium dioxide, antimony, bismuth, or compounds of Group V or V1 of the Periodic System may also be added.ALSO:Open-chain diamines are prepared by passing a dihydric aliphatic alcohol, an alkanolamine, alkylene oxide or hexamethyleneimine or mixtures thereof, with a stoichiometric excess of ammonia or a primary or secondary amine, in the presence of at least 2 litres of hydrogen per mole of alcohol, alkanolamine, alkylene oxide or hexamethyleneimine, in the presence or absence of water, at 150-300 DEG C. at a pressure of at least 10 atmospheres, over a catalyst containing at least one of the metals silver, copper, iron, cobalt and nickel, said catalyst having been prepared by sintering. Examples prepare (1) ethylene diamine and piperazine from ethylene glycol and ammonia, and 1,2-diaminopropane similarly from 1,2-propanediol; (2) ethylene diamine and piperazine from ethanolamine, diethanolamine and ammonia, or from ethylene oxide and ammonia; (3), (4), (5) 1,6-hexamethylenediamine and hexamethyleneimine from 1,6-hexanediol and ammonia or hexamethyleneimine and ammonia; (6) N,N,N1,N1 - tetra ethyl ethylenediamine and N,N-diethylethanolamine from ethylene glycol and diethylamine; and (7) N-isopropyl-1,3-diaminopropane from 1,3-propanolamine and isopropylamine. Other reactants are listed.ALSO:Catalysts for the production of diamines (see Division C2) contain at least one of the metals silver, copper, iron, cobalt and nickel and are prepared by sintering the powdered metal in admixture with a carrier such as pumice, alumina, corundum, diatomaceous earth, silica gel, silicon carbide, silicates, porcelain or quartz, or by sintering oxides of the metal or compounds converted into oxides at sintering temperature, such as hydroxides, carbonates, nitrates and nitrites, in the presence of a carrier as above and/or a promoter such as alkali metal compounds, alkaline earth metal compounds, titanium dioxide, antimony, bismuth, or compounds of metals of Group V or VI of the Periodic System, and then reducing the sintered oxide with hydrogen.
