Description
(54) СПОСОБ ПОЛУЧЕНИЯ ТЕТРАЛЕВОЙ КИСЛОТЫ(54) METHOD FOR OBTAINING TETRAL ACID
кислоты, которую перекристаллизовывают на толуоле.acid, which is recrystallized in toluene.
Соотношение кислота : толуол равно 1 : 3. Выход тетралевой кислоты после перекристаллизации из толуола II г.The ratio of acid: toluene is 1: 3. The yield of tetralic acid after recrystallization from toluene II g.
Выход от теоретического - 80%, на прореагировавший продукт - 96%, на исходный - 27,5%. Чистота по данным ГЖХ- 98,5%.The output from the theoretical - 80%, on the reacted product - 96%, on the original - 27.5%. Purity according to GLC - 98.5%.
Предмет изобретени Subject invention
Способ получени тетралевой кислоты окислением тетралина кислородсодержащим газом при нагревании в присутствии катализатора с последуюш.им доокислением полученного при этом оксидата, содержащего гидроперекись тетралина, и выделением продукта известными приемами, отличающийс тем,The method for producing tetralic acid by oxidizing tetralin with an oxygen-containing gas when heated in the presence of a catalyst, followed by further oxidation of the resulting oxidate containing tetralin hydroperoxide, and isolating the product with known methods
что, с целью увеличени выхода продукта, в качестве катализатора прн окислении тетралина испо.тьзуют соли металлов I группы главной подгруппы Периодической системы элементов и процесс ведут до накоплени вthat, in order to increase the yield of the product, salts of metals of Group I of the main subgroup of the Periodic System of Elements are used as a catalyst for the oxidation of tetralin and the process is carried out before accumulation
оксидате не менее 25% гидроперекиси тетралина , а доокисление азотной кислотой. 2. Способ по п. 1, отличающийс тем, что в качестве солей металлов I группы главной подгруппы Периодической системы элементовoxidate at least 25% tetralin hydroperoxide, and oxidation with nitric acid. 2. The method according to claim 1, characterized in that as salts of metals of group I of the main subgroup of the Periodic Table of Elements
используют нафтенат лити , нафтенат кали .lithium naphthenate, potassium naphthenate are used.
