Description
Изобретение относитс к способам очистки ацетона.This invention relates to methods for purifying acetone.
Известен способ очистки ацетона путем ректификации .A known method of purification of acetone by distillation.
С целью получени ацетона высокой стенени чистоты, который может пр-имен тьс в электровакуумной и полупроводниковой промышленности , предлагают способ, заключающийс в том, что перед ректификацией ацетон обрабатывают перманганатом кали в «присутствии безводного основного реагента, например соды. Желательно брать пермаигалат кали и соду в микроколичествах, например 0,0025 и 0,316 вес. % от вз того ацетона, и рехтифищировать при флегмовом числе не менее 6.In order to obtain high purity acetone, which can be referred to in the electrovacuum and semiconductor industries, a method is proposed that the acetone is treated with potassium permanganate in the presence of an anhydrous basic reagent, for example soda, prior to distillation. It is advisable to take potassium permaigalat and soda in trace amounts, for example, 0.0025 and 0.316 wt. % of acetone taken, and rehashchifirovat when reflux ratio of not less than 6.
При,мер. 500 мл ацетона (395,2 г) загружают в колбу с мешалкой и туда же ввод т 0,01 г иермангаиата кали и 1,25 г безводной соды. После 15 мин перемешивани ацетон декантируют и загружают в куб ректификационноп колонны. Ацетон особой чистоты отбирают цри флегмовом числе, равном 6.Example. 500 ml of acetone (395.2 g) were charged into a flask with a stirrer, and 0.01 g of potassium germaniumate and 1.25 g of anhydrous soda were added thereto. After 15 minutes of stirring, the acetone is decanted and rectification columns are loaded into the cube. High purity acetone is taken at a reflux ratio of 6.
Выход целевого продукта составл ет 88,5% от исходного ацетона.The yield of the target product is 88.5% of the starting acetone.
