Claims (1)

В способе получения уксусной кислоты карбонилированием метанола в присутствии родиевого катализатора карбонилирования, иодистого метила и стабилизатора в виде соли иодистоводородной кислоты поддерживают ограниченную концентрацию воды до примерно 10 мас.% и концентрацию метилацетата не менее 2 мас.% в жидкой реакционной среде и извлекают продукт - уксусную кислоту - путем пропускания жидкой реакционной среды через зону воспламенения для получения паровой фракции, которую пропускают через единую дистилляционную колонну, из которой продукт - уксусная кислота - удаляется.In a process for producing acetic acid, carbonylation of methanol in the presence of a rhodium carbonylation catalyst, methyl iodide and a stabilizer in the form of a hydroiodic acid salt maintains a limited water concentration to about 10 wt. acid - by passing the liquid reaction medium through the zone of ignition to obtain a vapor fraction, which is passed through a single distillation column, from which kt - acetic acid - is removed.
