The present invention relates to a method for producing aliphatic alcohols directly from a mixture of carbon monoxide and hydrogen (hereinafter abbreviated as synthesis gas) in the liquid phase.
More specifically, the present invention relates to a novel method for producing lower aliphatic monohydric alcohols or polyhydric alcohols such as methanol, ethanol, and ethylene glycol. Many studies have been conducted on methods for directly producing lower aliphatic alcohols from synthesis gas in the liquid phase. As a result, catalysts containing Group Group elements of the periodic table, especially rhodium or ruthenium, have been used for aliphatic alcohols,
It is known to be particularly active in the production of ethylene glycol. However, these catalysts have not been commercially realized because their activity and selectivity are still insufficient, and it is difficult to recycle them. As a result of intensive studies on the use of ruthenium compound catalysts for the above synthesis reaction, the present inventors found that by adding orthonitroanilines, aliphatic alcohols, especially ethylene glycol, can be efficiently removed from synthesis gas. The present invention was achieved based on these findings. In addition, JP-A-55-115834 and JP-A-57-
No. 82328 proposes a method in which a Lewis base-containing compound is used as a co-catalyst in a solubilized ruthenium carbonyl complex as a main catalyst. These publications describe various alkali metal halides, alkaline earth metal salts, iminium salts, amines, etc. as examples of Lewis bases. However, the Lewis bases described in the examples are only the above three, and there are no specific examples of organic nitrogen bases. Moreover, the performance of the ruthenium-based catalysts found in the above-mentioned prior art cannot be said to be sufficient for the production of ethylene glycol. However, the present inventors have discovered a novel fact that among amines, orthonitroanilines have a specifically effective function. That is, in the present invention, in producing aliphatic alcohols by reacting a mixture of carbon monoxide and hydrogen in a liquid phase in the presence of a ruthenium compound, the following formula is used.

しては、下式[Formula] (In the formula, R 1 , R 2 , R 3 , R 4 , and R 5 each represent hydrogen or a lower alkyl group.) It is characterized by adding orthonitroanilines represented by the following into the reaction system. The present invention provides an industrially excellent method for producing aliphatic alcohols. Examples of the ruthenium compound used in the present invention include oxides, hydroxides, inorganic acid salts, halides, carboxylic acid salts, and complex compounds having various ligands containing nitrogen, phosphorus, oxygen, atoms, etc. It will be done. Specific examples thereof are ruthenium dioxide, ruthenium tetroxide, ruthenium dihydroxide, ruthenium nitrate, ruthenium chloride, ruthenium bromide, ruthenium iodide, ruthenium formate, ruthenium acetate, tris(acetylacetonate)ruthenium, dodecacarbonyltriruthenium. , pentacarbonylruthenium, bis(tri-n-butylphosphine)tricarbonylruthenium, dibromotricarbonylruthenium, undecacarbonylhydridotriruthenium tetraphenylphosphonium, dipotassium tetracarbonylruthenate, cesium octadecacarbonylhexarthenate, Cyclopentadienyldicarbonylruthenium, ruthenocene, etc. Among these ruthenium compounds, carbonyl compounds or compounds that can be converted into carbonyl compounds in the reaction system are particularly preferred. These ruthenium compounds can be used in the form of either homogeneous or heterogeneous catalysts in the liquid phase. When used in a heterogeneous form, it is usually supported on a suitable carrier and subjected to the reaction. In the method of the present invention, by adding orthonitroanilines to the catalyst made of the above-mentioned ruthenium compound, the catalyst performance, particularly the ethylene glycol production activity, can be significantly improved. The orthonitroanilines used in the present invention include the following formula:

R 2 , R 3 , R 4 and R 5 each include hydrogen or a lower alkyl group having 1 to 4 carbon atoms. Specific examples of preferred orthonitroanilines include o-nitroaniline, 2-nitro-m-toluidine, 2-nitro-p-toluidine, o-nitro-N-methylaniline, and the like. There is no particular restriction on the type of solvent used in the method of the present invention, but preferred solvents are ketones, alcohols, ethers, carboxylic acids, carboxylic acid anhydrides, esters, lactones, amides,
These include sulfones, sulfoxides, aliphatic or aromatic hydrocarbons, solid salts that melt below the reaction temperature, and mixtures thereof. In the method of the present invention, the concentration of the ruthenium compound in the reaction system is usually in the range of 0.001 to 1 mol/. The amount of orthonitroanilines added is determined by the ratio of the number of moles of orthonitroanilines to the number of g atoms of ruthenium contained in the ruthenium compound (A/Ru
Usually expressed as a ratio of 1/1000 to 10000/1
, preferably from 1/100 to
It is 1000/1. The reaction pressure, expressed as the sum of the partial pressures of carbon monoxide and hydrogen, is usually in the range of 50 to 3000 Kg/cm 2 , preferably 100 to 1500 Kg/cm 2 . The molar ratio of carbon monoxide and hydrogen is 1/10 to 10/
It is appropriate that the value be within the range of 1. Also, nitrogen,
Gases inert to the reaction may be present, such as argon, methane, carbon dioxide, etc. The reaction temperature is preferably in the range of 100 to 450°C, more preferably 200 to 350°C. The reaction according to the present invention can be carried out either continuously or batchwise. Products such as methanol, ethanol, and ethylene glycol obtained according to the method of the present invention can be easily separated from the reaction solution by known separation operations (eg, distillation, extraction, etc.). If the catalyst used is a heterogeneous catalyst, it can be easily separated, for example, by separation. In addition, in the case of a homogeneous catalyst, the residual liquid after separating the desired product can be used as is.
It can also be recycled to the reaction system and reused. Hereinafter, the present invention will be explained in more detail with reference to Examples, but the present invention is not limited thereto. Examples 1 to 5 and Comparative Example 1 After purging the inside of a shaking type Hastelloy C autoclave with an internal volume of 30 ml with nitrogen, Ru 3 (CO) 12 containing 0.1 mg-atom of ruthenium and a predetermined amount of ortho as a promoter were added. Nitroanilines and specified solvents
7.5 ml, the contents were mixed well, and the autoclave was closed. CO in the autoclave/
Synthesis gas having a H 2 molar ratio of 1/1 was injected under pressure until a predetermined pressure was reached, and the autoclave was heated at a predetermined temperature for 3 hours while shaking to carry out a reaction. After the reaction was completed, the autoclave was cooled to room temperature, most of the gas was slowly released, the pressure was returned to normal pressure, the reaction solution was taken out, and the product was analyzed by gas chromatography. The results are shown in Table 1. The value of "reaction pressure" in the table indicates the maximum pressure reached during the reaction and the pressure at the end of the reaction. EG is ethylene glycol, MeOH is methanol,
EtOH stands for ethanol. THF and TGM represent tetrahydrofuran and tetraethylene glycol dimethyl ether, respectively.
