It is a method for producing compositions using alcohol as a starting material and comprising: allowing alcohol to contact with an alcohol conversion catalyst such as hydroxyapatite (first step) and conducting a hydrogenation reaction respectively for all reaction products consisting of a liquid phase including alcohols, water and hydrocarbons of 4-12 carbons and a gas phase which is light gas containing paraffins, alcohols and olefins; all liquid phase reaction products consisting of all reaction products from which light gas has been removed; a liquid phase dehydration reaction products consisting of all reaction products from which light gas, unreacted alcohol and product water have been removed; and light gas (second step).
The present invention is to provide a novel method for manufacturing various organic compounds from two or more kinds of alcohol, or one kind of alcohol having three or more carbon atoms. It is a method for synthesizing one kind of, or two or more kinds of organic compounds comprising allowing two or more kinds of alcohol or one kind of alcohol having three or more carbon atoms to contact a calcium phosphate catalyst such as hydroxyapatite, or hydrotalcite.

An objective of the present invention is to provide intestinal absorptive antitumor agents with an excellent intestinal absorptive effect by using injectable antitumor agents. In the intestinal absorptive pharmaceutical agents of the present invention, antitumor components that can be used only as injections are supported by hydroxyapatite particles.
Disclosed is a process for producing a composition comprising an organic compound, which is useful as a chemical industrial raw material or a fuel composition, by using an alcohol such as ethanol as a starting material. Specifically disclosed is a process for producing an organic compound by using an alcohol as a starting material, which comprises the following steps: contacting the alcohol with an alcohol conversion catalyst such as hydroxyapatite (first step); and hydrogenating each of a whole reaction product of the first step, a liquid-phase whole reaction product and a liquid-phase dehydrated reaction product, wherein the whole reaction product is composed of a liquid phase comprising an oxygen-containing compound (e.g., an alcohol, an aldehyde), water, a hydrocarbon having 4 to 12 carbon atoms and the like and a gaseous phase that is a light gas comprising a paraffin, an olefin, a diene, an alcohol and the like, the liquid-phase whole reaction product is produced by removing the light gas from the whole reaction product, and the liquid-phase dehydrated reaction product is produced by removing the light gas, an unreacted portion of the alcohol and the produced water from the whole reaction product (second step). Thus, a fuel composition for an internal combustion engine is produced, which is improved in the stability against oxidation.

It is intended to provide a recalcification promoter for the dental enamel, which can highly effectively promote the recalcification of the dental enamel and strongly inhibit tooth decay, and a composition for the oral cavity. Namely, a recalcification promoter for the dental enamel and a composition for the oral cavity characterized by comprising amorphous hydroxyapatite and/or amorphous hydroxyapatite showing two peaks at 2ϑ=31 to 35° in X-ray diffractometry. This amorphous hydroxyapatite can be obtained by reacting a calcium salt with a phosphoric acid salt in an aqueous solution and drying at a temperature of 10 to 70°C.
Disclosed is an intestinal absorptive anti-tumor agent for injection having an excellent intestinal absorptive effect. The intestinal absorptive agent comprises hydroxyapatite particles and an anti-tumor ingredient that can used only in the form of an injection supported on the particles.
