    Abstract: A process for producing an alcohol by continuously passing a fatty acid ester, a fatty acid triglyceride or a fatty acid through a hydrogenation catalyst to thereby produce the aimed alcohol through catalytic reduction is disclosed, wherein the employed reactor is a fixed bed reactor in which the liquid phase and the gas phase are continuously passed together in descending parallel flows through the hydrogenation catalyst fixed in the reactor; and at least one cooling mean for cooling the reaction system is provided at a position in the vertical direction of the reactor. According to the process of the present invention with the use of a fixed bed reactor, an alcohol, which has extremely high qualities and a high purity and is contaminated with little hydrocarbon and aldehyde by-products, can be produced. The process of the present invention further makes it possible to omit the post-treatment for eliminating the by-products.

    Abstract: A process for the production of an alkyl glycoside or an aqueous solution thereof is disclosed, comprising the steps of (1) reacting a sugar with alcohol to obtain an alkyl glycoside reaction product containing unreacted alcohol, (2) establishing a moving liquid film of the alkyl glycoside reaction product and (3) contacting the moving liquid film with steam or an inert gas at a temperature of from 50 to 200 DEG C. The alkyl glycoside or aqueous solution thus obtained contains little unreacted alcohol and is excellent in hue and odor.

    Abstract: A process for producing desulfurized fats and oils or fatty acid esters is disclosed, which comprises treating fats and oils or fatty acid esters under hydrogen or a mixture of hydrogen and an inert gas atmosphere at a pressure of from 0.1 to 500 kg/cm2 in the absolute pressure at a temperature of from 100 DEG to 350 DEG C. in the presence of a catalyst of the following formula (I): CuxXxxYyxOz(I) wherein all symbols are defined in the disclosure. A process for producing an alcohols using desulfurized fats and oils or fatty acid esters is also disclosed. According to the process for producing an alcohol of the present invention, an alcohol of a high purity and good qualities can efficiently and effectively be produced.

    Abstract: A process for producing an alcohol from a fatty acid ester, a fatty acid triglyceride or a fatty acid by continuously catalytically reducing the starting material in the presence of a hydrogenation catalyst is disclosed. In the process of the present invention, two reactors (i.e., the main reactor located upstream and the after reactor located downstream) being located in series are employed. In the process of the present invention, two reactors are employed and the temperatures thereof are individually controlled, whereby the conversion ratio is elevated while suppressing the formation of hydrocarbon and aldehyde by-products. Thus, an alcohol of extremely high quality and high purity can be produced. Further, the process of the present invention makes it possible to omit any post-treatment for eliminating the by-products. Furthermore, the active life of the hydrogenation catalyst can be remarkably prolonged by using three reactors (i.e., the guard reactor, the main reactor and the after reactor).
