Problems solved by technology

[0003] As a method for synthesizing higher alcohols from methanol and ethanol, methods using heterogeneous catalysts such as MgO can be used (see Non-Patent Documents 1-5, Patent Documents 1-4), but due to many side reaction products and special reaction conditions, etc. without industrialization
In addition, as a method of synthesizing butanol from ethanol, a method using an oxide of an alkaline earth metal as a catalyst (see Non-Patent Document 6), a method using a zeolite substituted with an alkali metal (see Non-Patent Document 7), a method using A method of a mixture of metal oxides (see Non-Patent Document 8), and as a method of producing butadiene from ethanol, a method using a metal oxide or a mixture thereof (see Non-Patent Documents 9 to 11), using as The method of the mountain skin catalyst of porous acicular clay (see Patent Documents 5 and 6), etc., but cannot be industrialized due to the difficulty in preparing the catalyst and the high reaction temperature.
[0004] On the other hand, a method of synthesizing butanol, butadiene, or a fuel composition using a hydroxyapatite catalyst has been proposed (see Patent Documents 7 and 8), but this is a method using only ethanol as a raw material, and an organic compound that can be synthesized limited
That is, ethanol is a substance with 2 carbon atoms, so organic compounds with an odd number of carbon atoms cannot be synthesized, especially alcohols with an odd number of carbon atoms cannot be synthesized

Embodiment 1-1

[0062] (catalyst)

[0063] As a catalyst in Examples, hydroxyapatite prepared by a conventional method can be used. In addition, in the table, "HAP1" means hydroxyapatite with a Ca / P molar ratio of 1.66, "HAP2" means hydroxyapatite with a Ca / P molar ratio of 1.64, and "HAP3" means a Ca / P molar ratio of 1.61 of hydroxyapatite. In addition, in the catalyst of the comparative example, Mg(OH) 2 A substance obtained by boiling and hydrating MgO reagent (manufactured by Wako Pure Chemical Industries, Ltd.) in distilled water (see Ueda, W.; Kuwabara, T.; Ohshida, T.; Morikawa, Y. A. Low-pressure Guerbet Reaction over Magnesium Oxide Catalyst .J.Chem.Soc., Chem.Commun., 1990, 1558-1559), ZrO2 uses the reference catalyst (JRC-ZRO-5) of the Catalyst Society, and other reagents manufactured by Wako Pure Chemical Industries.

Embodiment 1-2

[0074] As raw material alcohol, ethanol and 1-propanol were used, and the mixing ratio was changed, and the reaction was carried out in the same manner as in Example 1-1. exist Figure 1 ~ Figure 3 The yield of alcohol relative to the reaction temperature is shown in .

[0075] Such as Figure 1 ~ Figure 3 As shown in , the types of alcohols produced differ depending on the mixing ratio (mol ratio). At a mixing ratio of 1:1, it was found that 1-pentanol was mainly synthesized as a linear alcohol. Therefore, when synthesizing straight-chain alcohols having an odd number of carbon atoms such as 1-pentanol, when the conversion ratios of the raw material alcohols are substantially equal, the mixing ratio is preferably around 1:1.

[0078] (catalyst)

[0079] The catalyst used was the same as in Example 1 above.

[0081] Except that the raw material alcohol is changed into a kind of alcohol with more than 3 carbon atoms, the reaction is carried out in the same way as in Example 1. For each test, organic compounds more than C2, organic compounds more than C4, alcohol (straight chain and branched chain) are measured. ), the yield of linear alcohols. The results are shown in Tables 5 to 7. In addition, no linear alcohol was produced in any of the test examples and comparative examples.

Abstract

The present invention is to provide a novel method for manufacturing various organic compounds from 2 or more kinds of alcohol, or 1 kind of alcohol having 3 or more carbon atoms. It is a method for synthesizing 1 kind of, or 2 or more kinds of organic compounds comprising allowing 2 or more kinds of alcohol or 1 kind of alcohol having 3 or more carbon atoms to contact hydroxyapatite (except those supporting metal catalysts or metal ion catalysts acting on alcohol).

Description

technical field [0001] This invention relates to organic compounds useful as feedstocks or fuel compositions in the chemical industry or to methods of synthesizing these mixtures. Background technique [0002] At present, as an industrial linear alcohol synthesis method, there is mainly an oxidation method in which normal aldehydes are synthesized by oxidizing normal olefins, and n-alcohols are synthesized by hydrogenating the obtained aldehydes. However, since naphtha, which is a raw material for normal olefins, is expensive, profitability has deteriorated. In addition to the oxidation method, a method using methanol (alcohol) and synthesis gas (carbon monoxide and hydrogen) as raw materials is also known. However, due to the use of harmful carbon monoxide and the high-pressure reaction, the equipment is enlarged and the profitability is deteriorated. In addition, the Ziegler method of oligomerizing ethylene by trialkylaluminum, followed by air oxidation to form long-chain...
