Description
Производительность 168 г на 1 л катализатора в 1 час.Productivity is 168 g on 1 l of the catalyst in 1 hour.
Пример 2. Катализатор, приготовленный по примеру 1 (3,9 г метавападата аммони и 117,6 г парамолибдата аммони в 500 мл концентрированной сол ной кислоты) содержит 3% V2O5 и 97% МоОз. Реакционную смесь состава, описанного в примере 1, подают в реактор при температуре 410°С.Example 2. The catalyst prepared according to Example 1 (3.9 g of ammonium meta-napadate and 117.6 g of ammonium paramolybdate in 500 ml of concentrated hydrochloric acid) contains 3% V2O5 and 97% MoO3. The reaction mixture of the composition described in example 1, is fed into the reactor at a temperature of 410 ° C.
Получают 2,6-диформилпиридина с выходом 49,8% в расчете на пропущенный и 60,7% - на прореагировавший 2,6-диметилпиридин.Get 2,6-deformylpyridine with a yield of 49.8% based on the missed and 60.7% - on the reacted 2,6-dimethylpyridine.
Пример 3. В реактор с катализатором (приготовление и состав катализатора по примеру 1) подают реакционную смесь (паровоздушную ), содержащую 0,5 л 2,4-диметилОкисление 2,6-диметилпиридина кислородом воздуха в Example 3. In a reactor with a catalyst (preparation and composition of the catalyst of example 1) serves the reaction mixture (vapor) containing 0.5 liters of 2,4-dimethyl oxidation of 2,6-dimethylpyridine with oxygen in the air
пиридина, 94,5 л воды и 72 л воздуха, с объемной скоростью 8400 час-. Температура в реакторе 410°С.pyridine, 94.5 liters of water and 72 liters of air, with a volumetric rate of 8400 hours. The temperature in the reactor is 410 ° C.
Получают 2,4-диформилпиридин с выходом 39% на пропущенное и 41%-на прореагировавшее сырье.Get 2,4-diformylpyridin with a yield of 39% for missing and 41% for the reacted raw materials.
В таблице приведены сравнительные данные известных и предлагаемого катализаторов .The table shows the comparative data of the known and proposed catalysts.
Как следует пз сравнительных данных, предлагаемый катализатор обеспечивает в реакции парциального окислени диметилпиридинов повышение выхода диформилпиридипов в 1,7-6 раз и более, чем трехкратное увеличение производительности процесса, достигающей 168 г диформилпиридина на 1 л каталиатора в час. присутстви .иевоокисных катализаторовAccording to the comparative data, the proposed catalyst in the reaction of partial oxidation of dimethylpyridines increases the yield of deformylpyridips by a factor of 1.7-6 and more than triple the productivity of the process, reaching 168 g of diformylpyridine per 1 liter of catalyst per hour. presence of oxide catalysts
