Description
Пример 1 . Испытание провод т на хроматографе. Цвет 3 66 с пламенно-ионизационным детектором на колонне длиной 3 м и внутренним диаметром 2,5 мм. В качестве газа-носител используют гелий, скорость кото рого 45 мл/мин. Неподвижную фазу нанос т в количестве -10% от веса твердого носител ТНД -ТС -М. Приготовленные насадки кондиционируют тфи максимально допустимых температурах фазы в течение 24 ч. Температура термостата колонок . Разделению подвергают смесь близкокип щи ароматических углеводородов, в частности производных бензола двух образцов. На фиг. 1 представлена хроматограмма 1-го образца, который состоит из этилбензола п-ксилола 2, о-ксилола 3, изопрошшбензола 4, мезитилена 5, псевдокумола 6, т-цимола , п-цимола 8, о-цимола 9; на фиг. 2 - хроматограмма 2-го образца следующего состава: пг -ксш1ол 1, п-ксилол 2, о-ксилол 3, т-цимол 4, п-цимол 5, о-цнмол 6. Изобретение позвол ет расширить ассортимент мономерных неподвижных фаз. Это особенно важно, так как в насто щее врем выбор селективных мономерных фаз дл газо-жидкостной хроматографии веществ с такими близкими температурами кипени , как бензольные углеводороды , ограничен. Кроме того, использование указанных эфиров в качестве фаз позвол ет обеспечить более селективное и эффективное разделение близкокип щих ароматических углеводородов . Таблица IExample 1 The test is performed on a chromatograph. Color 3 66 with a flame ionization detector on a column 3 m long and with an internal diameter of 2.5 mm. Helium is used as a carrier gas, the rate of which is 45 ml / min. The stationary phase is deposited in an amount of -10% by weight of the solid carrier TND -TC -M. The prepared nozzles condition the maximum permissible phase temperatures for 24 hours. The temperature of the column thermostat. A close mixture of aromatic hydrocarbons, in particular benzene derivatives of two samples, is subjected to separation. FIG. Figure 1 shows the chromatogram of the 1st sample, which consists of ethylbenzene p-xylene 2, o-xylene 3, isoprotein benzene 4, mesitylene 5, pseudocumene 6, t-cymoline, p-cymoline 8, o-cymol 9; in fig. 2 - chromatogram of the 2nd sample of the following composition: pg-x1x1ol 1, p-xylene 2, o-xylene 3, t-cymol 4, p-cymol 5, o-csmol 6. The invention allows to expand the range of monomeric stationary phases. This is especially important since at present the choice of selective monomer phases for gas-liquid chromatography of substances with such close boiling points as benzene hydrocarbons is limited. In addition, the use of these esters as phases allows for more selective and efficient separation of closely aromatic hydrocarbons. Table I
