[0071] Preparation example 1 (preparation of catalyst)

[0072] Catalysts were prepared by the impregnation method. That is, 20g of boehmite (trade name "Boehmite", manufactured by Wako Pure Chemical Industries, Ltd., average pore diameter: 77nm, specific surface area: 214m 2 / g) into the ammonium paratungstate aqueous solution (1), stirred for 16 hours, distilled off water with an evaporator, dried, and sintered at 800°C for 3 hours, thus obtaining tungsten-loaded boehmite, the ammonium paratungstate aqueous solution (1) is 2g (0.65mmol) (NH 4 ) 10 h 2 (W 2 o 7 ) 6 ·xH 2 O (manufactured by Aldrich) was dissolved in 200 mL of water.

[0073] The boehmite loaded with tungsten obtained by 2g was added in chloroplatinic acid aqueous solution (1), stirred for 12 hours, and described chloroplatinic acid aqueous solution (1) was 2% by weight of chloroplatinic acid aqueous solution (H 2 PtCl 6 : 0.2mmol) 4mL dissolved in 100mL deionized water to obtain.

[0076] Preparation example 2 (preparation of catalyst)

[0077] Except using chloroplatinic acid aqueous solution (2) instead of chloroplatinic acid aqueous solution (1), obtain catalyst (2) (Pt: 1% by weight, W: 8% by weight) in the same manner as Preparation Example 1, the chloroplatinic acid Aqueous solution (2) is 2% by weight chloroplatinic acid aqueous solution (H 2 PtCl 6 : 0.1mmol) 2mL dissolved in 100mL deionized water.

preparation example 3

[0078] Preparation example 3 (preparation of catalyst)

[0079] Catalyst (3) (Pt: 1% by weight, W: 8% by weight) was obtained in the same manner as in Preparation Example 2, except that the sintering conditions after impregnation were changed from 300°C for 3 hours to 500°C for 3 hours. .

Abstract

The invention is to provide a catalyst for hydrogenolysis of a polyhydric alcohol which can produce a hydrogenolysis product from a polyhydric alcohol selectively in a high yield even without using aliquid acid catalyst and to provide a method for producing 1,3-propanediol from glycerol using the catalyst. The catalyst for hydrogenolysis of the present invention is obtained by carrying a platinumcomponent and a tungsten component on boehmite as a carrier. The platinum component and the tungsten component [the former: the latter (weight ratio)] are preferably contained in the ratio of 1:0.05to 1:50. The catalyst for hydrogenolysis is preferably obtained by carrying a platinum component and a tungsten component on boehmite as a carrier, followed by baking at 200 to 1000 DEG C for 1 to 5 hours.

Description

[0001] This application is based on the fact that the filing date is August 29, 2013, the priority date is August 30, 2012, the application number is 201380045246.4 (international application number PCT / JP2013 / 073081), and the invention name is "catalyst for hydrogenolysis of polyols". , and a method for producing 1,3-propanediol using the catalyst" is a divisional application of the patent application. technical field [0002] The present invention relates to a polyalcohol hydrogenolysis catalyst capable of obtaining a hydrogenolyzed product from a polyalcohol such as glycerin selectively and at a high yield, and to a method for producing 1,3-propanediol using the catalyst. Background technique [0003] As the problems of unstable supply of fossil fuels and the greenhouse effect caused by carbon dioxide emissions are increasing, the use of biodiesel fuel derived from biological resources has become widespread as a means of solving these problems. However, a large amount of ...
