Анализ полученного образца дал следующие результаты, мае. %: ацетон 0,012(9,1), диоксан 0,018 (11,8), уксусна кислота 0,038 (24,7),hydrochloric acid, 0.001 methanol, 0.002 ethanol. After the addition of the internal standard, the obtained sample was processed according to the procedure described in Example 1. The analysis of the obtained sample gave the following results, May. %: acetone 0.012 (9.1), dioxane 0.018 (11.8), acetic acid 0.038 (24.7),
Пример 1. К навеске 10 г мо- ,Q метанол 0,008 (33), этанол 0,019 (21). нозтиленгликол высшего сорта добавл ют 0,001 г декана, прибавл ют 40 мл В скобках приведена ошибка опреде- хлористого бензоила, что соответствует массовому соотношению 1:4,8.Пробу хорошо перемешивают и охлаждают g до 2 С. Выпавшие кристаллы центрифугируют . Жидкую часть хроматографи- руют на хроматографе ЛХМ-8МД со стекл нной капилл рной колонкой с SE-30 при программировании температуры от 60 до 220° со скоростью 6 град/мин.Example 1. To a weight of 10 g of m-, Q methanol 0.008 (33), ethanol 0.019 (21). top grade grafted glycol added 0.001 g of decane, 40 ml added. The error in the determination of benzoyl is given in parentheses, which corresponds to a mass ratio of 1: 4.8. The liquid portion is chromatographed on an LHM-8MD chromatograph with a glass capillary column with an SE-30 with temperature programming from 60 to 220 ° at a speed of 6 deg / min.
В результате анализа обнаружены следующие соединени , мае. %: ацетон 0,001, уксусна кислота 0,0005, метанол 0,002, этанол 0,004, диоксан 0,004.As a result of the analysis, the following compounds were found, May. %: acetone 0.001, acetic acid 0.0005, methanol 0.002, ethanol 0.004, dioxane 0.004.
Пример 2. К навеске 10 г монозтиленгликол добавл ют, г: 0,001 ацетона, 0,002 диоксана, 0,005 уксуслени (отн,%).Example 2. To a weighed portion of 10 g of mono-thiene glycol was added, g: 0.001 acetone, 0.002 dioxane, 0.005 wixons (rel,%).
