きた。More specifically, the object of the present invention is an oxygen-containing compound having 2 carbon atoms and containing ethanol as a main component. Oxygen-containing compounds, particularly oxygen-containing compounds having two carbon atoms such as ethanol, have conventionally been produced by a petrochemical method using naphtha as a raw material.
しかし、近年の原油高騰により、製造価格の著しい上昇
が起り、原料転換の必要性が生じている。一方、豊富で
且つ安価に入手可能な一酸化炭素及び水素の混合ガスよ
り含酸素化合物を製造する方法が種々検討されている。However, due to the rise in crude oil prices in recent years, manufacturing prices have risen significantly, creating the need to switch raw materials. On the other hand, various methods have been studied for producing oxygen-containing compounds from a mixed gas of carbon monoxide and hydrogen, which is abundant and available at low cost.

化合物の選択率が低いものや含酸素化合物の選択率が高
い場合には主生成物の選択性が低いものであつた。That is, by reacting a mixed gas of carbon monoxide and hydrogen in the presence of a catalyst containing rhodium as a main component and consisting of a metal or metal oxide such as manganese, titanium, zirconium, or tungsten, an oxygen-containing compound having two carbon atoms is produced. Methods for selectively producing are known. However, even in this method, the amount of by-product hydrocarbon iodine, such as methane, is large, and the selectivity of the main product is low when the selectivity of oxygen-containing compounds is low or when the selectivity of oxygen-containing compounds is high. It was hot.

る。Furthermore, the amount of target compounds produced based on rhodium, which is an expensive precious metal, is still small, and the reality is that no technology has been developed that is economically or process-perfect. Furthermore, a catalyst for adding manganese to rhodium and its improvement method aimed at producing oxygen-containing compounds in high yield and with high selectivity (JP-A-52-1470 56-8333 and 56-
No. 8334) has been proposed, but both methods use acetaldehyde and acetic acid as the main products, and have the disadvantage that the yield and selectivity of ethanol are extremely low.

出し、本発明を完成した。As a result of extensive research into a method for selectively producing oxygen-containing compounds containing ethanol as the main component, the present inventors have found that:
As mentioned above, acetaldehyde is produced in the presence of a rhodium-mancan catalyst known as a catalyst for producing acetic acid with iron added thereto, or in the presence of a catalyst selected from the group consisting of vanadium, titanium, iridium, and nickel. They discovered that ethanol can be selectively obtained by reacting carbon monoxide and hydrogen in the presence of a catalyst, and completed the present invention.

のを使用することができる。The method of supporting is to prepare a mixed solution in which a raw material compound containing rhodium, manganese and iron, or a component selected from the group of vanadium, titanium, iridium and nickel is simultaneously dissolved in the same solvent, and to simultaneously support them on a carrier. Various techniques can be used, such as a method in which each component is supported on the carrier sequentially, or a method in which each component is subjected to a reduction heat treatment as necessary and supported sequentially or in stages. Other preparation methods, such as a method of supporting a metal by ion exchange using the ion exchange ability of a carrier, and a method of preparing a catalyst by a coprecipitation method, are also adopted as a method for preparing the catalyst used in the present invention. can. The catalyst prepared by the above-mentioned method is usually activated by reduction treatment and then subjected to reaction. In order to carry out the reduction, it is convenient and preferable to carry out the reduction using a hydrogen-containing gas at an elevated temperature. At this time, the reduction temperature is the temperature at which rhodium is reduced, that is, 10
Although the reduction treatment can be carried out at a temperature of about 0°C, it is preferably carried out at a temperature of 200°C to 600°C. At this time, hydrogen reduction may be carried out while raising the temperature gradually or stepwise from a low temperature in order to sufficiently disperse each component of the catalyst. Further, reduction can also be carried out chemically using a reducing agent. For example, reduction treatment may be performed using carbon monoxide and water, or using a reducing agent such as hydrazine, a borohydride compound, or an aluminum hydride compound. The carrier used in the present invention preferably has a specific surface area of 10 to 1000 rI1Iy and a pore diameter of 10 A or more, which is commonly known as a carrier.
