Cyclododecane and cyclododecene are obtained from 1,5,9-cyclododecatriene and ciscyclooctane from 1,5-cyclooctadiene, as by-products in reaction with CO + H2 in presence of catalysts comprising compounds of Co-Cu-Cr or Co-Ag-Zn-Ca-Cr.ALSO:Cyclododecylmethanol and cyclooctylmethanol are prepared from 1,5,9-cyclododecatriene and 1,5-cyclooctadiene respectively, by reaction with CO + H2 in presence of a catalyst mixture of (a) a Co or Pd compound or finely divided Pd and (b) as a CO-inert hydrogenation component, Cu/Cr oxide, Pt or Ag/Zn/Cr oxide. Specified by-products are formyldodecane, formyloctane, bis-(dodecylmethyl) ether and bis-(octylmethyl) ether.ALSO:Catalysts for oxo-synthesis (see Division C2) comprise (a) a Co or Pd composed or finely-divided Pd and (b) as a CO-inert hydrogenation component, Cu/Cr oxide, Pt or Ag/Zn/Cr oxide. Specified catalysts comprise (1) Co2 (CO)8 + a component precipitated from Cu (NO3)2 and Na2Cr2O7; (2) Co2(CO)8 + a component precipitated from Ag, Ca and Zn nitrates and (NH4)2 Cr2O7; and (3) as in (1) but substituting Co acetate + pyridine for Co2 (CO)8. |
