Description
(54) СПОСОБ ХРОМАТОГРАФИЧЕСКОГО ВЫДЕЛЕНИЯ ОРГАНИЧЕСКИХ ВЕЩЕСТВ(54) METHOD OF CHROMATOGRAPHIC ISOLATION OF ORGANIC SUBSTANCES
выделенное вещество. Полученные углеводороды (бензол, толуол, м-ксилол) анализируют на насадочной колонке длиной 2 м и с внутренним диаметром 4 мм (неподвижна фаза- азоксифенетол). Они оказываютс хроматографически чистыми, что отвечает дл выбранных условий чистоте не ниже 99%. Полноту удалени и улавливани определ ют путем вторичного ввода выделенного вещества к колонку и улавливани . В различных опытах полученное вторично количество вещества колеблетс в пределах 93-97% от первоначально уловленного.isolated substance. The resulting hydrocarbons (benzene, toluene, m-xylene) are analyzed on a packed column 2 m long and with an internal diameter of 4 mm (stationary phase — azoxyphenetol). They are chromatographically pure, which is responsible for the selected conditions with a purity of at least 99%. Completeness of removal and trapping is determined by secondary entry of the isolated substance to the column and trapping. In various experiments, the secondary amount of the substance varies between 93-97% of the initially caught.
Пример 2. При тех услови х опыты провод т с использованием в качестве подвижной фазы смесей вод ного пара с этиловым спиртом в соотношени х 60 : 40; 80 : 20; 95 : 5. В ловушках образуетс двухфазна система, причем одной из жидких фаз был сконденсированный смешанный элюент (вода и спирт), а другой - сконцентрированный компонент раздел емой смеси (н-гексан, н-гептан, н-октан ) при чистоте до 99,5%. Было установлено изменение времени удерживани сорбатов при изменении состава подвижной фазы.Example 2. Under those conditions, the experiments were carried out using mixtures of water vapor with ethyl alcohol as a mobile phase in ratios of 60: 40; 80:20; 95: 5. A two-phase system is formed in the traps, with one of the liquid phases being a condensed mixed eluent (water and alcohol) and the other a concentrated component of the mixture to be separated (n-hexane, n-heptane, n-octane) with purity up to 99 ,five%. The change in the retention time of the sorbates with the composition of the mobile phase was found.
Пример 3. При тех же услови х опыты провод т с использованием в качестве подвижной фазы смеси вод ного пара с н-бутиламином в соотношении 95 ; 5. Выдел ют парафиновые и ароматические углеводороды (пгексан , н-гептан, н-октан, бензол, толуол, сумма м- и п-ксилолов, о-ксилол) при чистоте 98-99,2%.Example 3. Under the same conditions, the experiments were carried out using as a mobile phase a mixture of water vapor with n-butylamine in a ratio of 95; 5. Paraffin and aromatic hydrocarbons (pyhexane, n-heptane, n-octane, benzene, toluene, the sum of m- and p-xylenes, o-xylene) are isolated with a purity of 98-99.2%.
Аналогичные результаты получены при использовании других неорганических газов, например аргона, гели и двуокиси углерода.Similar results were obtained using other inorganic gases, such as argon, gels, and carbon dioxide.
Предмет изобретени Subject invention
Способ хроматографического выделени органических веществ путем пропускани смеси органических веществ через хроматографическую колонку с использованием в качестве элюента вод ного пара с последующим улавливанием и конденсацией их, отличающийс тем, что, с целью повышени степени чистоты органических веществ, в качестве элюента используют смесь вод ного пара с паром органического соединени , например этилового спирта, или с неорганическим газом при соотношении соответственно от 1 I до 100: 1.A method of chromatographic separation of organic substances by passing a mixture of organic substances through a chromatographic column using water vapor as eluent followed by capturing and condensing them, characterized in that, in order to increase the purity of the organic matter, water vapor mixture is used as eluent steam of an organic compound, for example ethyl alcohol, or with an inorganic gas at a ratio of 1 to 100: 1, respectively.
