Description
i
. Изобретение относитс к способу получе- . :ни акрилонитрила, широко примен емого в
|Качестве исходного мономера при произвол-; ютве синтетического волокна и других ис кусственных материалов.;
Известен способ получени акрилонитри-
.па путем окислительного амыонолиза пропилена кислородомвоздуха при ЗОО-500 С, мол рном соотношении пропилен: кислород; аммиак, равном 1: 1-5:0, 1,5, давлении не выше 5 атм в присутствии вод ного пара и катализатора на основе кислородсодержащего соединени теллура с последующим выделением целевого продукта известными приемами..
Конверси пропилена при этом относительно образовани акрилонитрила составл ет 31%, селективность 54%, относительно образовани побочного ацетонитрила 12,4%.
Недостатком такого способа вл етс не высока селективность процесса, сопровождающегос значительным вьтходом побочных продуктов.
. Целью изобретени вл етс повышение селективности процессаг, обеспечиваюшей уве-
личение выхода целевого продукта и снижение выхода побочных продуктов, в частност ацетонитрила.
; Поставленна цель достигаетс тем, что в качестве катализатора примен ют смесь кислородсодержащих соединений теллура и титана при атомном соотношении теллур: титан, равном 1-1О:5-1.
Это позвол ет повысить степень конверсии пропилена по акрилонитрилу до 65%, а селективность - до 62% при снижении селективности по побочному ацетонитрилу до 2-3%.
Катализатор, примен емый в предлагаемом способе, может быть использован в виде смеси кислородсодержащих соединений тзллура и титана, а также с добавкой аруrv соединений, в том числе соединений элементов , вход щих в п тую группу. Периодической системы, например соединений фосфора . Добавку соединений этих элементов ввод т в таком количестве, что атомное от- :н6шение добавл емого элемента к сумме титана и теллура не превышает 1:5.
