Claims (1)

Способ производства уксусной кислоты карбонилированием метанола и/или его реакционноспособных производных при давлении 2,0-5,0 МПа (20-50 бар) с пониженным образованием карбонильного загрязнения, характеризующийся тем, что метанол и/или его реакционноспособные производные взаимодействуют с оксидом углерода и водородом при парциальном давлении водорода, по меньшей мере, 0,2 МПа (2 бара), при подаче водорода в процесс в мольном отношении к оксиду углерода менее 1: 10, в жидком реакционном составе, включающем (а) родиевый катализатор, (б) метилгалогенид и (в) соединение рутения.A method of producing acetic acid by carbonylation of methanol and / or its reactive derivatives at a pressure of 2.0-5.0 MPa (20-50 bar) with reduced formation of carbonyl pollution, characterized in that methanol and / or its reactive derivatives interact with carbon monoxide and hydrogen at a partial pressure of hydrogen of at least 0.2 MPa (2 bar), when hydrogen is supplied to the process in a molar ratio to carbon monoxide of less than 1: 10, in a liquid reaction composition comprising (a) a rhodium catalyst, (b) methyl halogen id and (c) a ruthenium compound.
