Claims (8)

1. Процесс получения метакрилатовых сложных эфиров, в котором (а) пропин отпаривают в дистилляционной колонне из потока растворителя, содержащего растворенный пропин, с получением потока газообразного пропина, который впоследствии конденсируют, и (b) конденсированный пропин подвергают взаимодействию с монооксидом углерода и спиртом в присутствии катализатора карбонилирования, отличающийся тем, что пропин отпаривают в дистилляционной колонне, которая оборудована внутренним конденсатором для образования частичной конденсации для подачи орошения.1. A process for producing methacrylate esters, in which (a) propine is evaporated in a distillation column from a solvent stream containing dissolved propine to produce a propine gas stream which is subsequently condensed, and (b) the condensed propine is reacted with carbon monoxide and alcohol in the presence of a carbonylation catalyst, characterized in that the propine is steamed in a distillation column, which is equipped with an internal condenser to form a partial condensation for heating and irrigation. 2. Способ по п.1, в котором газообразный пропин впоследствии конденсируется в общем конденсаторе на верху ректификационной колонны и собирается в барабане накопителя, где он смешивается со спиртом. 2. The method according to claim 1, in which gaseous propine subsequently condenses in a common condenser at the top of the distillation column and is collected in a storage drum, where it is mixed with alcohol. 3. Способ по п.1, в котором газообразный пропин впоследствии конденсируется в общем конденсаторе на верху ректификационной колонны посредством контакта с охлажденным спиртом или охлажденной смесью спирта и пропина. 3. The method according to claim 1, in which gaseous propine is subsequently condensed in a common condenser on top of the distillation column by contact with a cooled alcohol or a cooled mixture of alcohol and propine. 4. Способ по любому из пп.1 - 3, в котором пропин отпаривают из растворителя в дистилляционной колонне, работающей при давлении в диапазоне от 0,01 до 5,0 бар (0,01 • 105 - 5,0 • 105 Па), температуре у основания в диапазоне от 120 до 230oC и температуре у вершины в диапазоне от -25 до +35oC.4. The method according to any one of claims 1 to 3, in which propyne is evaporated from the solvent in a distillation column operating at a pressure in the range from 0.01 to 5.0 bar (0.01 • 10 5 - 5.0 • 10 5 Pa), the temperature at the base in the range from 120 to 230 o C and the temperature at the top in the range from -25 to +35 o C. 5. Способ по любому из пп.1 - 4, в котором пропин отпаривают из растворителя в дистилляционной колонне, работающей при давлении в диапазоне от 0,1 до 3,0 бар (0,1 • 105 - 3,0 • 105 Па), температуре у основания в диапазоне от 130 до 210oC и температуре у вершины в диапазоне от -15 до +25oC.5. The method according to any one of claims 1 to 4, in which propyne is evaporated from the solvent in a distillation column operating at a pressure in the range from 0.1 to 3.0 bar (0.1 • 10 5 - 3.0 • 10 5 Pa), the temperature at the base in the range from 130 to 210 o C and the temperature at the top in the range from -15 to +25 o C. 6. Способ по любому из пп.1 - 5, в котором пропин отпаривают из растворителя в дистилляционной колонне из 6 - 20 теоретических тарелок. 6. The method according to any one of claims 1 to 5, in which propyne is evaporated from the solvent in a distillation column of 6 to 20 theoretical plates. 7. Способ по любому из пп.1 - 6, в котором внутренний конденсатор установлен так, чтобы конденсировать приблизительно две трети потока пара. 7. The method according to any one of claims 1 to 6, in which the internal condenser is mounted so as to condense approximately two-thirds of the steam stream. 8. Способ по п.6, в котором внутренний конденсатор функционирует с орошением 1 - 20 м3/час и потребляет энергию с интенсивностью 90 - 2000 кВт.8. The method according to claim 6, in which the internal capacitor operates with irrigation 1 to 20 m 3 / h and consumes energy with an intensity of 90 to 2000 kW.
