Ethanol and acetaldehyde using cobalt compounds with novel promoters

Ethanol and acetaldehyde using cobalt compounds with novel promoters. Lin, Jiang Jen; Knifton, John F. (Texaco Inc. , USA). U.S. US 4476326 A 9 Oct 1984, 7 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C07C045-49. NCL: 568487000. APPLICATION: US 83-463380 3 Feb 1983. DOCUMENT TYPE: Patent CA Section: 45 (Industrial Organic Chemicals, Leather, Fats, and Waxes) EtOH [64-17-5] and AcH [75-07-0] are prepd. by the reaction of MeOH [67-56-1] with CO and H at 50-350°/3500 psi in the presence of a catalyst system comprising a Co compd. and a promoter selected from organosulfur compds., N-contg. compds., and 1,1'-bis(diphenylphosphino)ferrocene (I) [12150-46-8]. Thus, a reactor contg. Co2(CO)8 0.34, I 0.14, and p-dioxane 14.0 g was pressurized to 1000 psi with a 1:2 (molar) CO-H mixt., heated to 180°, pressurized at 4000 psi with synthesis gas for 16 h, and cooled to give 23.9 g liq. product. The conversion of MeOH was 82%. The product contained EtOH 58, AcH 7, PrOH 14, and AcOMe 5%. The product contained 4605 ppm Co (96% Co recovery). A similar homologation run without I gave 78% conversion of MeOH to a product contg. 67% EtOH and 4% AcH, but the Co recovery was 2%.

Catalyst for hydroformylation of olefins

Catalyst for hydroformylation of olefins. Hsu, Chao Yang (Sun Tech, Inc., USA). U.S. US 4528278 A 9 Jul 1985, 5 pp. (English). (United States of America). CODEN: USXXAM. CLASS: ICM: B01J023-42. ICS: B01J027-08; B01J031-22. NCL: 502153000. APPLICATION: US 84-598933 11 Apr 1984. DOCUMENT TYPE: Patent CA Section: 45 (Industrial Organic Chemicals, Leather, Fats, and Waxes) Section cross-reference(s): 23 Catalysts comprising a Pt compd., such as Pt acetylacetonate (I) [15170-57-7], a ferrocene-derived ligand, such as 1,1'-bis(diphenylphosphino)ferrocene (II) [12150-46-8], and a group IVB metal halide, such as SnCl2, exhibit high activity in the hydroformylation of olefins and high selectivity to linear aldehydes. Thus, a 300-mL reactor contg. 100 mL p-xylene, 0.5 mmol I, 2.5 mmol SnCl2.2H2O, and 0.5 mol II was pressurized to u500 psi with synthesis gas, heated to 100°, charged with 250 mmol propene [115-07-1], pressurized to 1000 psi with synthesis gas, and heated 1 h at 100° under synthesis gas at 1000 psi, giving an 82% yield of butyraldehydes contg. 88.6% linear PrCHO [123-72-8].
