Изобретение относится к производству эфиров, которые могут быть использованы например, как высокооктановые добавки к моторным топливам. Способ получения эфиров взаимодействием олефинов и спиртов в присутствии твердого ионитного катализатора при повышенных температуре и давлении в аппарате с раздельными зонами ректификации и несколькими зонами реакции, в которых, катализатор полностью или частично погружен в жидкость, включающий пропускание парового потока из каждой нижерасположенной зоны ректификации в вышерасположенную зону ректификации, сквозь слой катализатора - 50<199>70% от общего количества парового потока и остальное по полым вертикальным каналам. Соотношение потоков проходящих через полые вертикальные каналы и сквозь слой катализатора регулируют путем частичного перекрытия полых вертикальных каналов. Предпочтительно сквозь слой катализатора пропускают паровой поток в количестве от 5 до 35% от общего количества парового потока, поступающего из нижерасположенной зоны ректификации.The invention relates to the production of esters, which can be used for example, as high-octane additives to motor fuels. The method of obtaining esters by the interaction of olefins and alcohols in the presence of a solid ion-exchange catalyst at elevated temperature and pressure in the apparatus with separate rectification zones and several reaction zones in which the catalyst is completely or partially immersed in a liquid, including passing a vapor stream from each downstream rectification zone to the upstream rectification zone, through the catalyst bed - 50 <199> 70% of the total amount of the steam flow and the rest through the hollow vertical channels. The ratio of the streams passing through the hollow vertical channels and through the catalyst bed is regulated by partial overlapping of the hollow vertical channels. Preferably, a vapor stream is passed through the catalyst bed in an amount of from 5 to 35% of the total amount of the vapor stream coming from the downstream rectification zone.
