Description
Известен способ получени ротундина путем многократной экстракции сырь гор чим керосином, извлечени ротундина из керосинового экстракта серной кислотой, осаждени основани содой, очистки его кристаллизацией с последующим переведением в хлоргидрат . Однако технологи изготовлени ротундина весьма сложна.A known method of producing rotundin is by repeatedly extracting the raw material with hot kerosene, removing rotundin from the kerosene extract with sulfuric acid, precipitating the base with soda, purifying it with crystallization, and then converting it to the hydrochloride. However, the technology of manufacturing rotundin is very complicated.
По предлагаемому способусырье (высушенный сок клубней Стефании круглой) экстрагируют спиртом.According to the proposed method (dried juice of Stephanie’s round tubers) is extracted with alcohol.
Пример. I кг сырь экстрагируют 7 л спирта при перемешивании в течение 30 мин; спиртовой раствор (6 л) отфильтровывают, сырье повторно экстрагируют спиртом и вновь заливают спиртом из расчета 1 кг сырь на 1 л спирта Второй слив второй загрузки используют дл получени первого извлечени третьей загрузки. Всего получают четыре извлечени общим объемом 24 л, концентрируют их в вакууме до 1,5 л; выпавший в осадок ротундин промывают спиртом и сушат , получают 97 г ротундина. Маточник упаривают до 300 Л1л и выдел ют еще 28 г основани . Все полученное техническое основание (125 г) раствор ют в семикратном объеме эталона, осветл ют углем, фильтруют и приливают сниртовой раствор сол ной кислоты. Получают 118 г хлоргидрата ротундина. После упаривани маточника до /з объема выдел ют дополнительно 15 г препарата. Весь хлоргидрат кристаллизуют из спирта. Из 3 кг сырь по 1учают 122 г чистого хлоргидрата ротундина.Example. I kg of raw material is extracted with 7 liters of alcohol with stirring for 30 minutes; the alcohol solution (6 l) is filtered off, the raw materials are re-extracted with alcohol and re-filled with alcohol at the rate of 1 kg of raw materials per 1 l of alcohol. The second discharge of the second load is used to obtain the first extraction of the third load. In total, four extracts with a total volume of 24 liters are obtained, and they are concentrated in vacuo to 1.5 liters; the precipitated rotundin is washed with alcohol and dried; 97 g of rotundin are obtained. The mother liquor is evaporated to 300 ml and another 28 g of base are isolated. All the obtained technical base (125 g) was dissolved in a sevenfold volume of the standard, lightened with charcoal, filtered and poured with a solution of hydrochloric acid. 118 g of rotundin hydrochloride are obtained. After evaporation of the mother liquor to / from the volume, an additional 15 g of the drug is isolated. All hydrochloride is crystallized from alcohol. Out of 3 kg of raw material, 122 g of pure rotundin hydrochloride are produced.
