The present invention relates to a method of carrying out an organic reaction in aqueous solution in the presence of a hydroxyalkyl(alkyl)cellulose or an alkylcellulose.

The present invention relates to a method for manufacturing a catalyst for synthesizing a fatty acid methyl or ethyl ester and a method for manufacturing a fatty acid methyl or ethyl ester using the catalyst. It provides a method for manufacturing a solid catalyst by mixing the oxides of manganese as active catalytic material and the soda lime glass as carrier wherein the content of the oxides of manganese is in the range of 0.1 w % to 70 w %, molding the mixture to spherical or cylindrical shape and sintering the molded catalyst. It also provides a method for manufacturing fatty acid methyl or ethyl ester with high purity by reacting fatty acid or a mixture of oil and fatty acid with methanol or ethanol by placing the solid catalyst in the reactor.
