The preparation of maleic anhydride by the oxidation of benzene, consisting of vanadium, molybdenum, and cobalt oxides with the addition of an alkali metal, deposited on a carrier.
Предложенный катализатор характеризуетс новым количественным составом активных окислов и добавок и содержит (в о/о): окисла ванади 56,4, окисла молибдена 27,9, окисла кобальта 4,6 и натри 1,1. В качестве носител катализатора использован низкопористый корунд с пористостью 0,7-90/0.The proposed catalyst is characterized by a new quantitative composition of active oxides and additives and contains (in o / o): vanadium oxide 56.4, molybdenum oxide 27.9, cobalt oxide 4.6 and sodium 1.1. Low-porous corundum with a porosity of 0.7-90 / 0 was used as a catalyst carrier.
Предложенный катализатор вл етс стабильным и активным. Выход малеинового ангидрида на нем равен 57-61 /оПример . 6,84 г ванадиевокислого аммони раствор ют в 650 мл 10о/о-ной сол ной кислоты, 2,6 г молибденовокислого аммони раствор ют в 55 мл воды, 2,63 г хлористого кобальта вместе с 0,5 г сернокислого натри раствор ют в 35 мл воды. Приготовленные растворы сливают в выпарную чашку, наход щуюс на кип щей вод ной бане, добавл ют 100 г носител и упаривают раствор, осторожно перемещива в конце упаривани . Воздушносухой катализатор Подвергают термической обработке в муфельной печи без доступа воздуха при следующем температурном режиме: до 175°С - 1 час, 175-320°С- 0,5 час, 320-400°С-0,5 час, 400°С -5 час.The proposed catalyst is stable and active. The yield of maleic anhydride on it is 57-61 / oExample. 6.84 g of ammonium vanadium acid are dissolved in 650 ml of 10 ° / hydrochloric acid, 2.6 g of ammonium molybdate are dissolved in 55 ml of water, 2.63 g of cobalt chloride are dissolved in 0.5 g of sodium sulfate 35 ml of water. The prepared solutions are poured into an evaporating dish on a boiling water bath, 100 g of carrier is added and the solution is evaporated, carefully moving at the end of evaporation. Air-dry catalyst Heat treated in a muffle furnace without air access under the following temperature conditions: up to 175 ° C - 1 hour, 175-320 ° C - 0.5 hour, 320-400 ° C - 0.5 hour, 400 ° C - 5 hours

Окись алюмини обрабатывают при кипении 15о/о-ной сол ной кислотой, отмывают от кислоты н высушивают на воздухе.The alumina is treated at boiling with 15 ° / hydrochloric acid, washed from acid and dried in air.
К 100 г сухой АЬО, добавл ют 1 г ТЮ и тщательно растирают смесь. Затем прибавл ют lOo/0-ный водный раствор 2,3 г декстрина , повторно тщательно растирают и формуют из полученной пасты цилиндрические гранулы размером 4-6 мм.To 100 g of dry ABO, add 1 g of TU and carefully triturate the mixture. Then add an oO / 0-th aqueous solution of 2.3 g of dextrin, re-triturate and form cylindrical granules of 4-6 mm in size from the resulting paste.
Дл получени носител с пористостью 0,90/0 воздущносухие гранулы подвергают обжигу при 1470° С в течение 5 час.To obtain a carrier with a porosity of 0.90 / 0, the air-dry granules are fired at 1470 ° C for 5 hours.
