Catalyst is made by treating Ni/Al alloy with alkaline solution. A solution of a salt of an alkaline earth metal (pref. MgCl2) is added to the catalyst after decanting so that an alkaline earth metal hydroxide is formed in situ on the surface of the catalyst when it is dried. To carry out the reaction the feedstock, an amide forming agent (pref. NH3), and a gas which contains at least 50% by vol. H2 (pref. synthesis gas) in ratio 1:2 to 4:8 to 20 are passed over the catalyst. Suitable reaction conditions are 0.1 to 3.0 (pref. 0.6 to 2.0) 1/1/h at 120 degrees C - 200 degrees C and 36 to 70 atmos heres. The reaction is particularly selective, gives high yields, and the catalyst has a long life.

Process for the stereoselective hydrogenation of cyclic compounds

Номер: CH0000624917A5
Принадлежит: SCM CORP, SCM CORP.

The process of hydrogenation by means of elemental gaseous hydrogen in the presence of a hydrogenation catalyst applies to any cyclic compound possessing nonaromatic unsaturation, having a hydroxyl substituent at an asymmetric centre of the ring, and a carbon-carbon double bond which, after saturation by hydrogen, gives rise to an additional asymmetric centre in the ring. A stereoselective hydrogenation is produced which consists in the increased ease with which the H2 atom can approach the ring from the side where the -OH group is situated when working in the presence of a nickel catalyst whose active surface has, to a substantial degree, been deactivated by treatment with a modifier. The process applies, for example, to the preparation of d-isomenthol from d-trans-piperitol.

The present invention relates to a catalyst system. In particular the invention relates to a catalyst in the form of metal or an alloy that is encapsulated within a polymer shell or matrix. More specifically the invention is directed towards reactive catalytic metals that may be pyrophoric or otherwise reactive in air and/or susceptible to oxidation. In particular, the invention is concerned with catalysts based on nickel. Raney or sponge nickel is highly hazardous: a self-igniting solid; produces hazardous fumes when burning; causes irritation of the respiratory tract, nasal cavities; causes pulmonary fibrosis if inhaled; ingestion may lead to convulsions and intestinal disorders; causes eye and skin irritation; and chronic exposure may lead to pneumonitis and sensitization (“nickel itch”).

Method of producing amines

Номер: RU2484084C2
Принадлежит: Родиа Операсьон

FIELD: chemistry. SUBSTANCE: invention relates to an improved method of producing diamine compounds by hydrogenation of compounds which contain nitrile groups, reaction with hydrogen or a hydrogen-containing gas, in the presence of a Raney nickel based hydrogenation catalyst which contains iron, chromium and zinc as doping elements. The hydrogenation catalyst contains the following, with respect to weight content of metal elements: Al - 2-10%; Fe - 0.3-3%; Cr - 0.5-5%; Zn - 0.5-5%; Ni - the balance up to 100%. EFFECT: method increases selectivity of the process and reduces formation of impurities. 7 cl, 1 tbl, 6 ex РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) 2 484 084 (13) C2 (51) МПК C07C 209/48 (2006.01) C07C 211/12 (2006.01) B01J 25/02 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (21)(22) Заявка: 2011113984/04, 01.09.2009 (24) Дата начала отсчета срока действия патента: 01.09.2009 (72) Автор(ы): ЛЕТУРНЕЭР Дидье (FR), ВЕРДЬЕ Стефан (FR) (73) Патентообладатель(и): РОДИА ОПЕРАСЬОН (FR) R U Приоритет(ы): (30) Конвенционный приоритет: 09.09.2008 FR 08/04935 (43) Дата публикации заявки: 20.10.2012 Бюл. № 29 C 2 2 4 8 4 0 8 4 C 2 R U (56) Список документов, цитированных в отчете о поиске: RU 2190469 С2, 10.10.2002.
