Изобретение относитс к способу получени масл ного альдегида каталитическим дегидрированием бутилового спирта.This invention relates to a process for the preparation of oil aldehyde by catalytic dehydrogenation of butyl alcohol.
Известен способ получени масл ного альдегида путем дегидрировани бутилового спирта на цинкхромовомедном катализаторе с добавками марганца и титана 1. Недостатком известного способа вл етс низкий выход целевого продукта, не цревышающий 45%.A known method of producing oil aldehyde by dehydrating butyl alcohol on a zinc-chromium catalyst with manganese and titanium 1 additives. A disadvantage of the known method is the low yield of the desired product, which does not exceed 45%.
С целью повышени выхода целевого продукта предлагают способ, отличающийс от известного тем, что в качестве катализатора дегидрировани примен ют катализатор состава , %:In order to increase the yield of the target product, a method is proposed that differs from the well-known one in that a catalyst of composition is used as a dehydrogenation catalyst,%:

который перед применением восстанавливают в токе водорода. Восстановление катализатора провод т при 240-250°С в течение 7-8 ч при подаче водорода с объемной скоростью 40-50 Дл достижени оптимального выхода масл ного альдегида целесообразно процесс дегидрировани вести при подаче бутилового спирта с объемной скоростью 0,5- 1,0 Ч-1.which is restored before use in a stream of hydrogen. Catalyst reduction is carried out at 240–250 ° C for 7–8 h with hydrogen feed at a bulk velocity of 40–50. H-1.
Предлагаемый способ позвол ет получать масл ный альдегид с выходами до 65%.The proposed method allows to obtain oleagraldehyde with yields up to 65%.

предварительно восстановленного водородом при 250°С в течение 7-8 ч, объемна скорость водорода 50 .previously reduced by hydrogen at 250 ° C for 7-8 h, the volumetric rate of hydrogen is 50.
Дегидрирование бутилового спирта осуществл ют иа восстановленном катализаторе при 280°С, объемной скорости бутилового сиирта 0,5 ч. Реакцию ведут в течение 4 ч. Количество пропущенного бутилового спирта 64,8 г. Количество полученного сырца 63 г.Dehydrogenation of butyl alcohol is carried out with a reduced catalyst at 280 ° C, but the volumetric rate of butyl alcohol is 0.5 h. The reaction is carried out for 4 h. The amount of missed butyl alcohol is 64.8 g. The amount of the crude obtained is 63 g
