Abstract: A method for producing carbon monoxide, the method may comprise the steps of: (a) preparing an adsorption-conversion catalyst comprising a support, and an additive comprising at least one selected from the group consisting of an alkali metal and an alkali earth metal, supported on the support, and not substantially comprising Ni, Fe, Co, Cr, Cu, Ru, In, Rh, Pt, Au, and Pd elements; (b) bringing the adsorption-conversion catalyst into contact with a gas containing carbon dioxide to allow the adsorption-conversion catalyst to capture carbon dioxide; and (c) bringing the adsorption-conversion catalyst to which carbon dioxide is captured into contact with a reducing gas to produce carbon monoxide.

Abstract: Provided is a method of producing an aliphatic glycoside compound or a sugar fatty acid ester compound by subjecting an intramolecularly dehydrated sugar and an alcohol or carboxylic acid compound of an aliphatic hydrocarbon to an addition reaction in the presence of an acid catalyst.

Abstract: A method for producing a sugar fatty acid ester characterized in that a fatty acid ester and a saccharide are subject to a transesterification reaction using a weakly basic ion exchanger having a pKb of 3 to 7 as a catalyst.

Abstract: The invention provides a method for producing a sugar fatty acid ester characterized in that a fatty acid ester and a saccharide are allowed to react and transesterified using a weakly basic ion exchanger having a pKb of 3 to 7 as a catalyst. According to the invention, problems with use of a strongly basic anion exchanger, that is, the decomposition of the product sugar fatty acid ester simultaneously proceeds, and the reaction is difficult to control, are resolved, and a sugar fatty acid ester can be efficiently produced.

Abstract: An object of the present invention is to solve the various problems with the conventional process for producing a sugar fatty acid ester, such as a sucrose fatty acid ester (FASuc), and to provide a process which has advantages such as no production of a soap by-product and ease of separation between the catalyst and the product and also enables efficient synthesis by a simple operation under mild conditions in a flow system, and to provide a composition including the sugar fatty acid ester. The present invention is directed to a process for producing a sugar fatty acid ester by a transesterification reaction of a fatty acid ester and a saccharide using an anion exchanger as a catalyst, and to a composition including such a sugar fatty acid ester.

Abstract: A method is provided for manufacturing high-purity vitamin E compounds by selectively separating vitamin E compounds such as tocotrienols and tocopherols from oil raw materials such as deodorized distillate, and more specifically, a method is provided, applying to a rich fraction of vitamin E compounds, for obtaining high-purity vitamin E compounds by separating and removing only free fatty acids contained as impurities. The method comprises a process in which a solution containing vitamin E compounds and free fatty acids is placed in contact with a weakly basic anion exchanger, and the free fatty acids are preferentially adsorbed.
