Description
Известные способы получени пентадиеналей сложны.Known methods for the preparation of pentadienals are complex.
Предлагаемый способ получени пептадиеналей (например, пентадиен-2 ,4-ал и бутен-3-метилеп-2-ал -(а)-винилахролеина) отличаетс тем, что пиперилен и изопрен подвергают каталитическому окислению азотно-кислородной смесью в присутствии медных катализаторов с добавками окислов т желых металлов (Mo,W).The proposed method for the preparation of peptadienals (e.g. pentadiene-2, 4-al and butene-3-methylep-2-al - (a) -vinyl-chloraine) is characterized in that piperylene and isoprene are subjected to catalytic oxidation with a nitrogen-oxygen mixture in the presence of additions of heavy metal oxides (Mo, W).
Это позвол ет упростить процесс и использовать в качестве исходного сырь доступные диеновые углеводороды.This simplifies the process and uses available diene hydrocarbons as feedstock.
При осуществлении этого способа окисление пиперилена и изопрена провод т в стекл нном реакторе путем пропускани над катализатором смеси диена, кислорода и азота, вз тых в определенном соотношении при температуре 400-430°С и времени контакта 0,5-1 сек.In this process, the oxidation of piperylene and isoprene is carried out in a glass reactor by passing a mixture of diene, oxygen and nitrogen over the catalyst, taken in a certain ratio at a temperature of 400-430 ° C and a contact time of 0.5-1 sec.
Пример. Смесь пиперилена или изопрена, кислорода и азота, вз тых в соотношении 1:1, 3:2,7, пропускают над катализатором (медный катализатор с добавками окислов Мо, W, нанесенных на силит), помещенным в стекл нный реактор, обогреваемый баней при 400 430°С. Врем контакта 0,5-1 сек.Example. A mixture of piperylene or isoprene, oxygen and nitrogen, taken in a ratio of 1: 1, 3: 2.7, is passed over the catalyst (a copper catalyst with additives of Mo, W oxides deposited on silica) placed in a glass reactor heated 400 430 ° C. Contact time 0.5-1 sec.
В случае окислени пиперилена получают пентадиеналь-2,4 с температурой кипени 52-53°С при 48In the case of the oxidation of piperylene, pentadienal-2.4 is obtained with a boiling point of 52-53 ° C at 48
изопрена - бутен-3-метилен-2-ал -(а)-винилакролеин кипени 66-GB C при 25 мм рт. ст., ng 1,4925.isoprene - butene-3-methylene-2-al - (a) -vinyl acrolein; boiling 66-GB C at 25 mm Hg. Art., ng 1,4925.
Выходы пентадиеналей до 150 г с 1 уг катализатора в час. Селективность по кислороду 159/0.Pentadienale outputs up to 150 g from 1 corner of catalyst per hour. Oxygen selectivity 159/0.
При приготовлении катализатора носитель (силит с размером зерна 1; 5-3,0 мм) пропитывают гор чим раствором нитрата окиси меди, молибденовой кислоты и вольфрамата аммони . Выпаривают, высушивают в течение 2 час при 150°С и прокаливают при 240-250°С в течение 2 час. Состав катализатора в процентах от веса носител - СиО 1 5 МоОз 0,01, WOs 0,01.When preparing the catalyst, the carrier (silicate with a grain size of 1; 5-3.0 mm) is impregnated with a hot solution of copper oxide nitrate, molybdic acid and ammonium tungstate. Evaporated, dried for 2 hours at 150 ° C, and calcined at 240-250 ° C for 2 hours. The composition of the catalyst as a percentage of the weight of the carrier - CuO 1 5 MoOz 0.01, WOs 0.01.
