3393. ----- [SOCIÉTÉ CHIMIQUE DE LA GRANDE PAROISSE, AZOTE ET PRODUITS CHIMIQUES.]  [Organic Oxygen Compounds.]  French Patent 705,683, Feb. 7, 1930.  Chem. Abs., vol. 26, 1932,p. 151.

Aliphatic compounds containing O are made by the action of CO on H₂O or steam in the presence of catalysts composed of artificial zeolites prepared by the union of salts of a strongly alkaline nature with metallates (salts of amohoteric metals), with or  without the addition of neutral or practically neutral salts.  The catalysts contain at least 1 element from each of the series:  (1) K, Na, Li, V, Cr, Mo, Mn, Fe  Co, Ni, Ag, Cu, Zn, Cd, Pb, Sb, Bi, Ca, Sr, Ba; (2) Be, Mg, Al, Ce, rare earths, B, Si, Ti, Zr, Th, U, W.  The catalysts are prepared in a medium with a pH value between 8 and 6.8 and when they contain reducible metallates, may be reduced in 2 stages, first at about 200° with dilute reducing gas and then at 300°-500° under pressure with concentrated reducing gas.  Gives examples.
