Description

Известны способы получени  9, 10-дизамещенных 9,10-дигидроантрацена действием металлического натри  па антрацен с последующей обработкой полученного аддукта различными активными веществами , например йодистым метилом. При этом в качестве побочных продуктов часто образуютс  9-производные 9,10-дигидроантрапена.Methods are known for the preparation of 9, 10-disubstituted 9,10-dihydroanthracene by the action of metallic sodium anthracene, followed by treatment of the resulting adduct with various active substances, for example methyl iodide. In addition, 9-derivatives of 9,10-dihydroanthrapene are often formed as by-products.

В данном изобретении, с целью увеличепи  выхода 9-производных 9,10-дигидроантрацена, предлагаетс  металлический натрий примен ть в тонкодисперсном состо нии с размерами частиц до 10 мк в виде суспензии в метилале.In the present invention, in order to increase the yield of 9-derivatives of 9,10-dihydroanthracene, it is proposed to use metallic sodium in a finely divided state with a particle size of up to 10 microns as a suspension in methylal.

Пример. В сосуд, продуваемый азотом, помещают 23 в. ч. металлического натри  в виде суспензии в 50 в. ч. н-понана, 200 в. ч. метилал  и 89. в. ч. аптрацена. Смесь перемешивают в течение 8-10 час при температуре 30-32°, а затем обрабатывают на холоду избытком углекислоты. После обычных операций выдел ют 105-110 в. ч. практически чистой 9, 10-дигидроантрацепкарбоновой-9 кислоты.Example. In a vessel purged with nitrogen, placed 23 in. including metallic sodium in the form of a suspension in 50 in. h. n-pon, 200 c. including methylal and 89. c. h. aptracene. The mixture is stirred for 8-10 hours at a temperature of 30-32 °, and then treated in the cold with an excess of carbon dioxide. After the usual operations, 105-110 volts are isolated. including almost pure 9, 10-dihydroantapecarboxylic-9 acid.

Предлагаемый способ позвол ет весьма просто и с высокими выходами получить 9-замещенные 9,10-дигидроантрацена, которые могут быть использованы в качестве эмульгаторов, физиологически активных веществ и ценных полупродуктов дл  различных синтезов.The proposed method allows very simple and in high yields to obtain 9-substituted 9,10-dihydroanthracene, which can be used as emulsifiers, physiologically active substances and valuable intermediates for various syntheses.

Пред мет изобретени Present Invention

Способ получени  9-про,изводных 9, 10-дигидроантрацена путем взаимодействи  металлического натри  с антраценом и последующей обработки полученного продукта, папример, углекислотой, отличающийс  тем, что, с целью увеличени  выхода продукта, используют тонкодисперсный натрий с размерами частиц до 10 мк в метилале.The method of obtaining 9-pro, 9, 10-dihydroanthracene derivatives by reacting metallic sodium with anthracene and subsequent processing of the product obtained, for example, with carbon dioxide, characterized in that, in order to increase the yield of the product, finely dispersed sodium with particle sizes up to 10 microns in methylal .
