Saito, Toshihiro; Taniguchi, Nobuyuki; Mitarai, Kazuharu; Arimitsu, Satoshi; Yanagi, Katsumi; Takada, Kazuo; Tanaka, Kazuaki (Agency of Industrial Sciences and Technology, Japan). Jpn. Kokai Tokkyo Koho JP 61178935 A2 11 Aug 1986 Showa, 6 pp. (Japan) CODEN: JKXXAF. CLASS: ICM: C07C031-08. ICS: B01J023-89; C07C029-15. ICA: C07C027-06. APPLICATION: JP 85-17727 2 Feb 1985. DOCUMENT TYPE: Patent CA Section: 23 (Aliphatic Compounds) Section cross-reference(s): 67 EtOH is prepd. from CO and H in the presence of a Rh-loaded catalyst and an Fe-loaded catalyst. Optionally Rh- and Li- and/or Sc-loaded catalysts or Rh-, Li-, Sc-, and Ir-loaded catalysts may be used instead of the Rh-loaded catalyst. Thus, 1.250 g RhCl3×3H2O was dissolved in 11.5 mL water, mixed with 25 mL silica gel, dried 1 h at room temp. and 18 h at 60°, and reduced with 180 mL/min H stream at 400° for 5 h to obtain a catalyst (A). Sep., 0. 10025-97-5 and 64-17-5 which are cas registry numbers are also used here.272 g FeCl2×4H2O was dissolved in 11.5 mL water, mixed with 25 mL silica gel, and treated same way as the above to obtain a catalyst (B). Then, 5 mL B was filled into a Ti tube (diam. 18 mm), mixed with 10 mL A dild. with 30 mL silica gel, reduced again with 400 mL/min 1:1 H/N mixt. at 200° for 1 h, and applied to reaction of 210 L/h 2.5:1 H/CO mixt. at 285° and 30 kg/cm2 to obtain a reaction product, showing CO conversion of 2.1 mol-% and selectivity to EtOH 40.0, MeCHO 5.7, HOAc 2.3, hydrocarbons (CH4, C2H6, and others) 45.5, and MeOH 4.3%. .

DOCUMENT TYPE: Journal CA Section: 67 (Catalysis and Reaction Kinetics) Supported heterogeneous hydrogenating catalysts of high activity and stability can be prepd. by redn. of RhCl(P03)3, RhCl3.xH2O, or IrCl4.xH2O in cyclohexene or cyclohexane. With these catalysts substrates are hydrogenated without solvent, and turnover nos. are up to >20,000.Except for chemicals metioned above, 10025-97-5 and 14694-95-2 are also used. .
