PROBLEM TO BE SOLVED: To provide a novel method for manufacturing various organic compounds, above all linear alcohols or branched-chain alcohols, in superior yields from two or more kinds of alcohols or one kind of alcohol having at least 3 carbon atoms.SOLUTION: At least two kinds of alcohols (of which one kind being ethanol and at least one kind of other starting raw material alcohol being methanol, 1-propanol, 1-butanol, 1-pentanol, 1-hexanol, 1-heptanol, 1-octanol, or an unsaturated alcohol of any of these) are or one kind of alcohol having at least 3 carbon atoms is contacted with hydroxyapatite (excluding one supporting a metal catalyst or metal ion catalyst which acts on alcohols) at 200°C to 600°C.

PROBLEM TO BE SOLVED: To provide a 3DS (dental drug delivery system) home care agent and to provide a bacterial removing system of dental caries, periodontal diseases and opportunistic infection bacteria so as to carry out prophylaxis of diseases in the oral cavity. SOLUTION: The bacterial removing system of the dental caries, the periodontal diseases and the opportunistic infection bacteria is composed of a step of removing bacterial plaque formed of Streptococcus mutans etc., from the tooth surface, a step of coating the tooth surface with the 3DS home care agent having ≥1 wt.% content of low crystalline or amorphous hydroxyapatite and a step of washing the tooth surface.
