Изобретение относитс к производству адипиновой кислоты, примен емой в производстве найлона, гексаметилендиамина, пластификаторов , в лакокрасочной, фармацевтической и других отрасл х промышленности.This invention relates to the production of adipic acid used in the manufacture of nylon, hexamethylenediamine, plasticizers, in the paint and varnish, pharmaceutical and other industries.
Известен способ получени аднииновой кислоты каталитическим окислением циклогексанона кислородсодержащим газом в присутствии смешанного кобальт-марганец-бариевого катализатора при 60-100°С в среде карбоновой кислоты с последуюпдим выделением продукта известными приемами. Выход адипиновой кислоты 72%.A known method of producing adninic acid by the catalytic oxidation of cyclohexanone with an oxygen-containing gas in the presence of a mixed cobalt-manganese-barium catalyst at 60-100 ° C in a carboxylic acid medium, followed by separation of the product by known methods. The output of adipic acid 72%.
С целью повышени выхода целевого продукта и улучшени его качества предложено вести процесс в присутствии в качестве катализатора цериевых солей одноосновных алифатических кислот.In order to increase the yield of the target product and improve its quality, it was proposed to conduct the process in the presence of cerium salts of monobasic aliphatic acids as a catalyst.
Пример 1. 100 ч. циклогексанона (марки «ч) постененно при перемешивании ввод т в раствор каприлата цери в уксусной кислоте (0,3 вес. ч. каирилата цери и 50- 100 вес. ч. уксусной кислоты).Example 1. 100 parts of cyclohexanone (mark "h) are added, with stirring, to a solution of cerium caprylate in acetic acid (0.3 parts by weight of ceri-cerium and 50-100 parts of acetic acid) with stirring.
Реактор заполн ют кислородом и температуру реакционной смеси новышают до 80- 100° С. Через реакционную смесь непрерывно пропускают кислород.The reactor is filled with oxygen and the temperature of the reaction mixture is increased to 80-100 ° C. Oxygen is continuously passed through the reaction mixture.
Врем процесса окислени 2,5-3 час. После охлаждени реакционной смеси выпадаютThe oxidation time is 2.5-3 hours. After cooling, the reaction mixture falls out
кристаллы адициновой кислоты, которые отдел ют на фильтре Шотта и суншт на воздухе . Выход 92%; т. пл. 150°С.adicic acid crystals, which are separated on the filter SCHOTT and SUNST in air. Yield 92%; m.p. 150 ° C.
После первой кристаллизации адипиновойAfter the first crystallization of adipic

The catalyst and acetic acid are regenerated from the mother liquor.
Пример 2. 100 ч. циклогексана (марки «ч) постепенно нри перемещнвании ввод т в раствор энантоата цери (0,3 вес. ч. энантоата цери в 50-100 вес. ч. уксусной кислоты ). Процесс окислени провод т в течениеExample 2. 100 parts of cyclohexane (mark "h) were gradually introduced into the solution of cerium enanthoate (0.3 weight parts of cerium enanthoate in 50-100 weight parts of acetic acid) while moving. The oxidation process is carried out for
4-5 час в услови х, описанных в примере 1. Выход адипиновой кислоты 90%.4-5 hours under the conditions described in Example 1. Adipic acid yield 90%.
