実験手順: Ruf, U.S. Pat. No. 5,068,373, Entitled Method for the Preparation of Anhydrous Tin—(IV)—Carboxylates, issued Nov. 26, 1991, relates to a method of reacting metallic tin or tin (II) acetate with an excess of acetic anhydride to produce tin (IV) acetate. The tin (IV) acetate is separated from the reaction mixture and used as separated or, if desired, is subsequently converted to tin (IV) carboxylate having four or more carbon atoms by reaction with the appropriate carboxylic acid.

実験手順: Catalyst preparation was conducted as follows. That is, 1.5 g of commercial tin (II) acetate (a product of Kanto Chemical Company, Inc.) was dissolved in 150 ml of acetic acid with heating. The solution was cooled to room temperature to obtain a solution of tin acetate in acetic acid. 5 g of a commercial silicon dioxide powder having an average particle diameter of 25 μm (a product of Mizusawa Industrial Chemicals, Ltd.) was weighed in a 500-ml beaker, after which 200 ml of water was added to suspend the silicon dioxide powder therein. To the suspension being stirred were slowly added dropwise the above-prepared solution of tin acetate in acetic acid and 25 ml of an aqueous palladium nitrate solution containing 1 g/l of palladium, simultaneously. After the completion of the dropwise addition, the mixture was heated to 80° C. with stirring, to evaporate and remove the acetic acid and water in the mixture. The residue was dried to obtain a powder. The powder was calcined in an air stream at 500° C. for 1 hours and then reduced in a hydrogen stream at 250° C. for 1 hour to obtain a catalyst in which palladium and tin were supported in amounts of 0.5% by weight and 15% by weight, respectively, based on the weight of the silicon dioxide used.
