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: 1307301 Catalytic hydrogenation BADISCHE ANILIN- & SODA-FABRIK AG 24 April 1970 [26 April 1969] 19809/70 Heading C2C [Also in Divisions B1 and C5] A catalytic hydrogenation process comprises hydrogenating a hydrogenatable organic material at elevated temperature and pressure, the hydrogenatable material being in substantially liquid phase, in the presence of one or more supported metals in Groups VIII, VIIb or VIb of the Mendeleef Periodic Table acting as-catalyst, said catalyst having been made by spraying a shaped support with a solution or suspension containing one or more metals and/or compounds of metals contained in Group VIII, VIIb or VIb of the Mendeleef Periodic Table, at a temperature ranging from 150‹ to 500‹ C. Preferably basifying metal compounds and bonding agents are also sprayed on and after the spraying process the catalyst and support are heated to 300‹ to 1000‹ C. to convert the metal compounds to the corresponding oxides. Examples describe the catalytic hydrogenation of diamino diphenyl alkanes and their ethers to diamino dicyclohexyl alkanes and their ethers; of anilines and nitrobenzenes to cyclohexylamines, cycloalkanones and phenols to cycloalkanols, aliphatic nitriles to aliphatic amines and aliphatic carboxylic acids to aliphatic alcohols.
