Description
Известен способ получени аценафтенхинона и его производных с применением бутилнитрита и раствора газообразного хлористого водорода В бутиловом спирте.A method of producing acenaphthenquinone and its derivatives using butyl nitrite and a solution of gaseous hydrogen chloride in butyl alcohol is known.
Описываемый способ получени аценафтенхинона и его производных ло сравнению с известным имеет следующие преимущества: отпадает необходимость применени довитого и огневзрывоопасного бутилнитрита; исчезает необходимость применени газообразного хлористого водорода, корродирующего аппаратуру, и сокращаетс технологический процесс получени продукта.The described method for the preparation of acenaphthenquinone and its derivatives compared with the known one has the following advantages: there is no need for the use of poisonous and inflammable butyl nitrite; the need to use gaseous hydrogen chloride, a corroding apparatus, disappears, and the technological process of obtaining the product is reduced.
Особенность способа заключаетс в том, что к аценафтену или его галоидозамещенному в среде триэтиленгликол -лри нагревании прибавл ют нитрит натри и сол ную кислоту, после чего образующуюс смесь соответствующего аценафтенхинона и его монооксима выдел ют путем разбавлени водой и превращают в соответствующий аценафтенхинон известным приемом.The peculiarity of the method is that sodium nitrite and hydrochloric acid are added to acenaphene or its halogen-substituted in triethylene glycol-triple heating, after which the resulting mixture of the corresponding acenaphthenquinone and its monoxime are separated by diluting with water and transformed into the corresponding acenaphthenquinone by a known technique.
В качестве растворител примен ют техническую смесь полиэтилентликолей .A technical mixture of polyethylene glycols is used as a solvent.
Пример 1. К раствору 81,5 г аденафтена (имеющего т. пл. 91° и содержащего 95% основного вещества) в 800 мл триэтиленгликол , нагретому до температуры 100°, добавл ют 20 мл ЗО/о-ной сол ной кислоты и затем равномерно, в течение 2 час., прибавл ют одновременно 120 мл 30%-ной сол ной кислоты и 113,5 г сухого технического нитрита натри , поддержива температуру среды в пределах 98-104° и след за тем, чтобы среда была кислой (по реакции на конго). Затем размещивают в течение часа при 100° и выливают смесь в I л холодной воды. Остаток отфильтровывают и промывают водой и фильтраты используют дл регенерации растворител . Осадок размешивают со смесью из 740 млExample 1. To a solution of 81.5 g of adenaphthene (having a melting point of 91 ° and containing 95% of the basic substance) in 800 ml of triethylene glycol heated to a temperature of 100 °, add 20 ml of DO / o-hydrochloric acid and then 120 ml of 30% hydrochloric acid and 113.5 g of dry technical sodium nitrite are simultaneously added uniformly over 2 hours, maintaining the temperature of the medium in the range of 98-104 ° and the environment is acidic (according to reactions to congo). Then place for one hour at 100 ° and pour the mixture into I l of cold water. The residue is filtered and washed with water and the filtrates are used to regenerate the solvent. The precipitate is stirred with a mixture of 740 ml
