Abstract
Abstract A method of preparing carboxylic acid salts which comprises subjecting to oxidative dehydrogenation alcoholic oxygen containing organic compounds by heating same with alkali metal oxides or hydroxides in the presence of a catalyst in order to produce the corresponding carboxylic acid salts, wherein said catalyst is obtained by mixing solid carbon with one or more members selected from the group consisting of metals of the Group IB, Group II and Group IV classified in the periodic Table and their inorganic compounds.

Claim 1
Independent Claim
167 words
A PROCESS FOR PREPARING CARBOXYLIC ACID SALT FROM ALCOHOLIC OXYGEN-CONTAINING ORGANIC REACTANT SELECTED FROM THE GROUP CONSISTING OF PRIMARY ALCOHOLS, ALDEHYDES, ALDOLS, ESTERS ALKANOLAMINES AND ALUMINUM ALCOHOLATES, COMPRISING REACTING SAID ALCOHOLIC OXYGEN-CONTAINING ORGANIC REACTANT WITH AN ALKALI METAL COMPOUND SELECTED FROM THE GROUP CONSISTING OF ALKALI METAL OXIDES AND HYDROXIDES, UNDER OXIDATIVE DEHYDROGEGENERATION CONDITIONS OF A TEMPERATURE IN THE RANGE OF 150* TO 350*C AND A PRESSURE IN THE RANGE OF 2 TO 100 ATMOSPHERES, IN THE PRESENCE OF FROM 0.01 TO 10% BY WEIGHT, BASED ON THE WEIGHT OF SAID ALCOHOLIC OXYGEN-CONTAINING REACTANT, OF CATALYST CONSISTING ESSENTIALLY OF A MIXTURE OF (A) AT LEAST ONE MEMBER SELECTED FROM THE GROUP CONSISTING OF ZINC, COPPER, THE OXIDES OF METALS OF GROUP IB, GROUP II AND GROUP IV OF THE PERIODIC TABLE, ZINC CHLORIDE AND ZINC HYDROXIDE, AND (B) SOLID CARBONS HAVING A SURFACE AREA IN THE RANGE OF FROM 25 TO 1,700 M2/G, THE WEIGHT RATIO OF (A):(B) BEING IN THE RANGE OF ABOUT 100:1 TO 1:100.
