    00 The invention relates to a process for producing ethanol by bicarbonylation of methanol in the presence of a cobalt based catalyst. A method of producing ethanol is known. The interaction of methanol with carbon monoxide and hydrogen at ITS-ZIO C, a pressure of 280-350 atm in the presence of cobalt acetate and iodine at a molar ratio of Co / H of 1: 4-1; 2 IJ However, the yield of ethanol is 70-75g / h n sufficient. The closest in technical essence to the proposed is. method of producing ethanol by the interaction of methanol, carbon monoxide and water of the genus at 175-230 ° C and pressure of 681020 atm in the presence of cobalt acetate and iodine as a catalyst, and also ruthenium halide in an amount containing 0.05-0.12 g -at n 1 g-at cobalt f 2. The yield of ethanol in the conventional method is 350-400 g / h per liter of reaction mixture and 200 g / h per gram of cobalt. However, the application of the known method is limited due to the use of high pressure and insufficient yield of the target product. The aim of the invention is to increase the yield of ethanol. The goal is achieved by carrying out the process of producing ethanod by the interaction of methanol, carbon monoxide and hydrogen at 205-225 C, pressure of 145-260 atm in the presence of cobalt-free catalysts, containing the ionic halide of formula MX, where M is a metal selected from sodium, potassium, lithium, or ammonium X is bromine, iodine, and alkyl halide of formula Ry, where R is alkyl C — C, U iodine, bromine, at a molar ratio of K / Co equal to 6-100, U / Co equal to 14-41 and 1 RU / CO, equal to 5-13. Mostly, methyl iodide is used as the alkyl halide. iodide is used as the ionic halide. When this process is carried out at a cobalt concentration of 1.2-4.8 mg-at / l reaction medium; A distinctive feature of the proposed method is to carry out the process in the presence of a cobalt-free catalyst containing an ionic halide. Formula MX, where M is Sodium, potassium, lithium, or ammonium, X is iodine, bromine, and alkylg, and ogenide of the formula is Ry, where R is alkyl, Y is iodine, bromine, and with a molar X / Co ratio of 6 -100, U / Co equal to 14-41, and RU / Co equal to 5-13. Advantageously, in the process, g thyliodides are used as the alkyl halide, iodides are used as the ionic halide, and the process is carried out at a cobalt concentration of 1.2-4.8 mg atm / l of the reaction medium. Carrying out the process in such a manner makes it possible to increase the ethanol consumption to 4400 g / h per gram of cobalt. Example 1. A stainless steel autoclave with steel Z8-CNDT 17-12 (standards of the French Association; standardization) with a capacity of 250 ml is charged with 95 ml of methanol, 5 ml of water, 521 mg (3.67 mmol) of methyl iodide, 1.8 g (12 mmol) sodium iodide, 0.127 mg ata cobalt in the form of dicobaltoctacarbonyl and 0.657 ruthenium in the form of triunium dodecocarbonyl. After that, a pressure of 140 atm is established with a Co-Hj equicruleral mixture, then the temperature in the autoclave is adjusted at I 215 ° C for 25 minutes with intermixing. The pressure reaches 210 atm, it is maintained within the range of 220-260 atm by the period of the charging Co / H2 mixture 1: 2. The process is carried out for 1 hour and 15 minutes at the indicated temperature, then heating and stirring are stopped, the autoclave is cooled, the gas is removed, the reaction mixture is analyzed by gas chromatography. 15 g, 2 g of ethanol, 4.48 g of methyl oxide and ethyl and 0.88 g of diethyl ether are obtained. The output of ethanol is 160 g / hl of reaction mixture and 2100 g / h per cobalt. Carrying out the process under other conditions (Example 2-10) is analogous to Example 1. The conditions for conducting the reaction product are given in the table.
