Description
Предметом изобретени вл етс способ получени фенилуксусной кислоты нз фенилэтилового спирта. Производные фенилуксусной кислоты примен ютс как фармакологические активные препараты и ростовые гормоны.The subject of the invention is a process for the preparation of phenylacetic acid in terms of phenylethyl alcohol. Phenylacetic acid derivatives are used as pharmacological active agents and growth hormones.
Известно получение фенилуксусиой кислоты окислением фенилэтилового спирта марганцевокислым калием в щелочном растворе или хромпиком в сравнительно крепкой серной кислоте. Однако при этом выход продукта составл ет не более 15% от теоретического.It is known to produce phenylacetic acid by oxidizing phenylethyl alcohol with potassium permanganate in an alkaline solution or with a chromium peak in relatively strong sulfuric acid. However, the product yield does not exceed 15% of the theoretical one.
Особенность описываемого способа состоит в том, что окисление фенилэтилового спирта провод т перекисью марганца в слабокислой среде в присутствии катализатора-солей меди-или без него, что позвол ет получать фенплуксусную кислоту сThe peculiarity of the described method is that the oxidation of phenylethyl alcohol is carried out by manganese peroxide in a weakly acidic medium in the presence of catalyst salts of copper — or without it, which allows to obtain fenplucetic acid with
выходом более 50% от теоретического .yield more than 50% of the theoretical.
Пример. 122 г фенилэтилового спирта при температуре 40-80° и перемешивании постепенно приливают к смеси из 1200 мл 10%-ной серной кислоты, 200 г перекиси марганца и 20 г хлорной меди. После окислени спирта избыток перевод т в раствор добавлением сульфита натри .Example. 122 g of phenylethyl alcohol at a temperature of 40-80 ° and stirring are gradually poured into a mixture of 1200 ml of 10% sulfuric acid, 200 g of manganese peroxide and 20 g of copper chloride. After the alcohol has been oxidized, the excess is transferred to the solution by the addition of sodium sulfite.
После охлаждени отдел ют техническую фенилуксусную кислоту.After cooling, the technical phenylacetic acid is separated.
Предмет изобретени Subject invention
Способ получени фенилуксусной кислоты из фенилэтилового спирта, отличаюш,ийс тем, что окисление провод т перекисью марганца в слабокислой среде в присутствии катализатора--солей меди-или без него.The method of obtaining phenylacetic acid from phenylethyl alcohol is different, because the oxidation is carried out with manganese peroxide in a weakly acidic medium in the presence of a catalyst — with or without copper salts.
