    摘要: C.sub.4 compounds including n-butanol and n-butanal are produced by reacting methanol, hydrogen, and carbon monoxide, in the presence of a cobalt catalyst selected from the group consisting of (a) a cobalt carbonyl, (b) a hydrido cobalt carbonyl and (c) a cobalt-containing material convertible to a cobalt carbonyl or a hydrido cobalt carbonyl, an iodine promotor and a thiol defined by the formula:RSHwherein R is selected from the group consisting of saturated or unsaturated, straight or branched chain alkyl radicals having from one to 24 carbon atoms, cycloalkyl radicals having from three to 40 carbon atoms, aryl radicals having from six to 20 carbon atoms, aralkyl and alkaryl radicals having from six to 40 carbon atoms and halogen substituted derivatives thereof. A high degree of selectivity towards the formation of butanol and butanal is provided by using the cobalt entity and the thiol in a molar ratio in the range of about 2:1 to about 10:1, based on elemental cobalt and sulfur. The reaction is conducted at elevated temperature and pressure conditions for a time sufficient to convert methanol to n-butanol and n-butanal.

    摘要: The conversion of carbon monoxide and hydrogen to produce a mixture of low molecular weight hydrocarbons which, on a methane-free basis, contain a predominance of C.sub.2 -C.sub.6 paraffins is achieved using as the catalyst a rare earth metal promoted layered complex metal silicate composition characterized as having repeating units of the structural formula[(1-x)Ni.sup.a + xRu.sup.6 ].sub.n (OH).sub.4 Si.sub.2 O.sub.5.wH.sub.2 Owhere x is a number from 0 to 1, this number expressing the atomic fraction of the metals nickel and ruthenium; a is the valence of nickel; b is the valence of ruthenium; n is a number equal in value to that defined by the ratio6/[a(1-x) + bx]and w is a number ranging from 0 to 4. A rare earth promoted nickel chrysotile is the preferred catalyst.
