Description
8 Напр жение на алоктролиэврда стабилизируетс и не превышает 3,5-4 в, т, е, почти в 5 раз уменьшаетс расход электроэнергий р процессе электросинтеза рН среды в объ«ме раствора не измен етс . Пример. Вначале готов т сернокислый раствор наркотина при нагревании при рН б, постепенно добавл в дистиллированную воду наркотин и серную кислоту Е стехиомет- риче1ском соотношении. Довод т концентрацию наркотина до 0,5М и после этого заЗгружают в раствор сернокислый калий (2н) и хлористый кальций (4-5 г/л),Такой электролита залигвают в электролизер с графитовым анодом и никелевым катодом, Электролизер обогреваетс через вод ную рубашку. Электролиз проводитс при темпе- ратуре раствора 80 С при анодной плотности тока 1ОО-110 а/м (или 1-1,1 а/дм ) По окончании электролиза раствор сливают и охлаждают в еченйё 3-5 час до 10 С. При этом опианова кислота выпадает в осадок, ее отдел ют фильтрованием и про мыванием. Выход опиановой кислоты составл ет 90% от теоретического.8 The voltage on a galactrolide stabilizes and does not exceed 3.5-4 V, t, e, the power consumption is reduced almost 5 times in the process of electrosynthesis the pH of the medium in the solution volume does not change. Example. First, a narcotine sulphate solution is prepared by heating at pH b, gradually adding narcotine and sulfuric acid E to the distilled water at a stoichiometric ratio. The narcotine concentration is brought to 0.5 M and then potassium sulphate (2N) and calcium chloride (4-5 g / l) are loaded into the solution. Such electrolyte is poured into the electrolyzer with a graphite anode and nickel cathode. The electrolyzer is heated through a water jacket. Electrolysis is carried out at a solution temperature of 80 ° C with an anodic current density of 1OO-110 a / m (or 1-1.1 a / dm). At the end of the electrolysis, the solution is drained and cooled in 3-5 hours to 10 C. At the same time the acid precipitates and is separated by filtration and washing. The yield of opic acid is 90% of theoretical.
