Description
Известны способы отделени карбонилов кобальта из продуктов, полученных в процессе оксосинтеза, осноза П1ые на разложении карбонилов тем или иным способом с выделением металлического кобальта, который после отделени от реакционной массы вновь превращаетс в карбонил.Methods are known for separating cobalt carbonyls from products obtained in the process of oxosynthesis, based on P1e on the decomposition of carbonyls in some way with the release of cobalt metal, which, after separation from the reaction mass, is again converted to carbonyl.
Недостатком известных способов вл етс сложность их осуществлени .A disadvantage of the known methods is the complexity of their implementation.
Описываемый способ отделени карбонилов кобальта от реакционной массы, получаемой при синтезе альдегидов из окиси углерода, водорода и низших олефинов по сравнению с известными обеспечивает возможность возвраталсарбонилов кобальта без их разложени в производственный цикл, что позвол ет создать более простую технологическую схему оксосинтеза.The described method of separating cobalt carbonyls from the reaction mass obtained by synthesizing aldehydes from carbon monoxide, hydrogen and lower olefins, as compared to the known ones, makes it possible to return cobalt sarbonyls without decomposing them into the production cycle, which makes it possible to create a simpler oxosynthesis process.
Особенность способа состоит в том, что продукты синтеза отгон ют от карбонилов кобальта в вакууме при 28-30, а остающиес в кубовом остатке карбонилы кобальта возвращают в цикл.The peculiarity of the method is that the synthesis products are distilled off from cobalt carbonyls in vacuum at 28-30, and the cobalt carbonyls remaining in the vat residue are recycled.
Пример. Вз то 198 г катализата, полученного при карбонилировании пропилена. Растворитель - углеводородна фракци , выкипающчл до температуры 65°. Концентраци кобальта в растворе-0,16%.Example. This is 198 g of catalysate obtained by carbonylation of propylene. The solvent is a hydrocarbon fraction, boiling to a temperature of 65 °. The cobalt concentration in the solution is 0.16%.
Отгонку провод т в вакууме при 150 мл рт. ст. при 28-30°, получают 170 г дистилл та, в котором содержание кобальта составл ет 0,0015%.Distillation is carried out in vacuum at 150 ml of mercury. Art. at 28-30 °, 170 g of distillate are obtained, in which the cobalt content is 0.0015%.
Остаток в виде в зкой массы раствор ют в 152 г олефиносодержащей фракции бензина и направл ют на реакцию карбонилировани . Концентраци кобальта в растворе составл ет 0,19%. Реакцию карбонилировани ведут 30 мин. Содержание непредельных соединений в бензине составл ет 55%. В продукте карбонилировани найдено 39% альдегидов.The residue, in the form of a viscous mass, is dissolved in 152 g of the olefin-containing fraction of gasoline and sent to the carbonylation reaction. The cobalt concentration in the solution is 0.19%. The carbonylation reaction is carried out for 30 minutes. The content of unsaturated compounds in gasoline is 55%. 39% aldehydes were found in the carbonylation product.
Предмет изобретени ISubject of invention i
Способ отделени карбонилов кобальта от реакционной массы, получаемой при синтезе альдегидов из окиси углерода, водорода и низших олефинов, отличающийс тем, что, с целью упрощени процесса, продукты синтеза отгон ют от карбонилов кобальта в вакууме ЗО, а остающиес в кубовом остатке :карбонилы кобальта возвращают в цикл.The method of separation of cobalt carbonyls from the reaction mass obtained in the synthesis of aldehydes from carbon monoxide, hydrogen and lower olefins, characterized in that, in order to simplify the process, the synthesis products are distilled off from the cobalt carbonyls in vacuum ZO, and those remaining in the bottoms: cobalt carbonyl return to cycle.
