1,233,129. Hydrogenation catalysts. INSTITUT FRANCAIS DU PETROLE DES CARBURANTS ET LUBRIFIANTS. 3 Sept., 1969 [5 Sept., 1968; 24 Dec., 1968; 17 Feb., 1969], No. 43555/69. Heading B1E. [Also in Division C5] Hydrogenation catalysts comprise the reaction product of (1) a transition metal compound, particularly of Co, Ti, Cr or Fe, with (2) an aluminium compound of formula Me(AlH m X 4-m )p wherein m is 1, 2 or 3, Me is a Group IA or IIA metal, p is the valency of Me, and the X radicals are each R, OR, NR 2 , NHR or SR, R being an organic group, with the proviso that two X radicals may be joined to form an -A-Z-B- or -O-A-ZB-O- group, wherein A and B are alkylene radicals, and Z is alkylene, oxygen, sulphur, NH, N-hydrocarbyl, or a polyvalent metal. An electron donor may also be present, e.g. an ether, amine, heterocyclic compound, phosphine oxide or phosphine. The catalysts may be supported, e.g. on molecular sieves, alumina or silica. Many components (1) and (2) and particular combinations are specified, typical transition metal compounds being CoBr 2 , CoBr 2 [PO(octyl) 3 ] 2 , Ti(SPh) 2 (cyclopentadiene) 2 , FeCl 3 and a complex of chromium chloride with PO(C 8 H 17 ) 3 . |
