фонировани  отсто вшейс  жидкости пасту снова перевод т в суспензию в 2,5 л воды и нагревают до 60 С. Затем прибавл ют 30 г окиси вольфрама WOj, потом 60,4 г нитрата меди СиШО)- . Аммиак ввод т, пока рН не достигнет 6,3-6,5. После осаждени , декантации и сифонировани  отсто вшейс  жидкости пасту отмывают при перемешивании 4 л холодной воды в течение 10 мин, затем отдел ют фильтрацией, высушивают в течение 12 ч при . 10 вес.ч. воды добавл ют к 100 вее.ч. сухого порошка и перемешивают, добавл   10,2 г окиси теллура, ТеО, высушивают при 120°С, добавл ют графит (1% по весу) и таблетируют.Spraying the liquid paste into the suspension is again transferred to a suspension in 2.5 liters of water and heated to 60 ° C. Then 30 g of tungsten oxide WOj are added, then 60.4 g of copper nitrate SISO) -. Ammonia is injected until the pH reaches 6.3-6.5. After precipitation, decantation and siphoning of the supernatant, the paste is washed with stirring 4 liters of cold water for 10 minutes, then separated by filtration, dried for 12 hours at. 10 weight.h. water is added to 100 wt. dry powder and stirred, added 10.2 g of tellurium oxide, TeO, dried at 120 ° C, graphite (1% by weight) was added and tableted.

Таблетки 4 х 4 мм подвергают термической обработке в токе воздуха в течение 16 ч при .Tablets 4 x 4 mm are subjected to heat treatment in a stream of air for 16 h at.

90 г приготовленного катализатора (атомное отношение Sb : Sn ; W i : Си : Те 4 : 2 : 0,25 t 0,5 : : 0,125) помещают в U -образную стекл нную трубку (двн 10 мм) и нагреваю в ванне из расплавленных нитратов до .90 g of the prepared catalyst (atomic ratio Sb: Sn; W i: Cu: Te 4: 2: 0.25 t 0.5:: 0.125) are placed in a U-shaped glass tube (dv 10 mm) and heated in a bath of molten nitrates to.

Через катализатор пропускают 27 л/ч смеси, содержащей, мол.%: 6Through the catalyst pass 27 l / h mixture containing, mol.%: 6

пропилена, 7 аммиака, 70 воздуха и 17 воды.propylene, 7 ammonia, 70 air and 17 water.

При зтих услови х 72,% пропилена превращаетс  в акрилонитрил, 6,5% в цианистоводородную кислоту, 0,9% в акролеин, 10% в COg, 5% в СО, 4,7% пропилена не вступает в реакцию.Under these conditions, 72% propylene is converted to acrylonitrile, 6.5% to hydrocyanic acid, 0.9% to acrolein, 10% to COg, 5% to CO, 4.7% of propylene does not react.
