Description
Известны способы гидрировани и гидроформилировани олефинов с применением карбонилов кобальта в качестве катализаторов. Однако эти способы не дают возможности регулировать соотношение выходов продуктов гидрировани и гидроформилировани .Methods are known for the hydrogenation and hydroformylation of olefins using cobalt carbonyls as catalysts. However, these methods do not allow adjustment of the ratio of the yields of the hydrogenation and hydroformylation products.
Предлагаемый способ позвол ет вли ть на характер протекающей реакции, увеличива выход продуктов гидрировани за счет подавлени реакции гидроформилировани или наоборот. С этой целью в качестве растворителей примен етс толуол (дл увеличени выхода альдегидов ) или метанол (дл увеличени выхода продуктов гидрировани ) .The proposed method allows to influence the nature of the reaction by increasing the yield of hydrogenation products by suppressing the hydroformylation reaction or vice versa. For this purpose, toluene (to increase the yield of aldehydes) or methanol (to increase the yield of hydrogenation products) is used as solvents.
По предлагаемому способу олефины подвергают обработке водородом и окисью углерода при повышенном давлении и повышенной температуре в присутствии катализаторов-карбонилов. кобальта. Например , при гидрировании и гидроформилировании а-метилстирола был получен альдегид с выходом 67% в следующих технологических услови х: температура 130°, водорода под давлением 270 атм, подача СО под давлением 60 атм, интервал изменени концентрации а-метилстирола 35-15%, растворитель-толуол.According to the proposed method, the olefins are treated with hydrogen and carbon monoxide at elevated pressure and elevated temperature in the presence of carbonyl catalysts. cobalt. For example, when hydrogenating and hydroformylation of a-methylstyrene, aldehyde was obtained with a yield of 67% under the following process conditions: temperature 130 °, hydrogen under pressure of 270 atm, supply of CO under pressure of 60 atm, interval of concentration of a-methylstyrene 35-15% solvent toluene.
При проведении процесса с применением в качестве растворител метанола выход изопропилбензола равен 93%.When carrying out the process using methanol as a solvent, the yield of isopropyl benzene is equal to 93%.
Таким образом, предлагаемый способ позвол ет в несколько раз увеличить выходы продуктов гидрировани и гидроформилировани .Thus, the proposed method allows several times to increase the yields of hydrogenation and hydroformylation products.
