Abstract
Применение окиси фенилUse of phenyl oxide
Description
ч.h
Изобретение относитс к неподвижным фазам, используемым в газовор хроматографии дл разделени смесей органических веществ, и может быть использовано в различных област х техники, где примен етс газохроматографический анализ.The invention relates to stationary phases used in a gas chromatography chromatography for the separation of mixtures of organic substances, and can be used in various fields of technology where gas chromatography analysis is used.
Целью изобретени вл етс нова неподвижна фаза, обладающа высокой селективностью разделени органических смесей, состо щих из нитропарафинов и аминов.The aim of the invention is a new stationary phase with a high selectivity of the separation of organic mixtures consisting of nitroparaffins and amines.
Существо изобретени состоит в использовании в качестве неподвижной фазы дл газовой хроматографии окиси фенил(2-цианэтил-2-диэтиламино)фосфина формулыThe essence of the invention consists in using as the stationary phase for gas chromatography oxides of phenyl (2-cyanoethyl-2-diethylamino) phosphine of the formula

Ранее указанное вещество использовали как полупродукт дл синтеза негорючих полимерных материалов,The previously mentioned substance was used as an intermediate for the synthesis of non-combustible polymeric materials.
Дл предлагаемой неподвижной фазы разность факторов пол рности, равна 4,15 между нитрометаном (6,02) и пиридином (1,87), значительно выше, чем у паиболе селективной к указан4982For the proposed stationary phase, the difference in polarity factors, equal to 4.15 between nitromethane (6.02) and pyridine (1.87), is significantly higher than that of the paibole selective to indicated
ной задаче разделени известной фазы 1,2,3-трис-( -1и1анэтокси)пропана (2,13). Такое различие в разности факторов пол рности позвол ет раздел ть на предлагаемой фазе смеси, которые не раздел ютс на известных фазах. Кроме того, при высокой селективности предлагаемой фазы на ней меньше врем удерживани компонентов , что уменьшает врем анализа.Noah the problem of separation of the known phase 1,2,3-tris- (-1i1etoxy) propane (2,13). Such a difference in the difference in polarity factors allows the mixture to be divided in the proposed phase, which are not separated in the known phases. In addition, with a high selectivity of the proposed phase, the retention time of the components on it is less, which reduces the analysis time.
Пример. Разделению подвергалась смесь трет-бутиламина, втор-бутиламина , нитрометана и бутиламина на колонке длиной 2 м,заполненной 10% 1, 2,3-трис(/з-цианэтокси)пропана , и колонке с 10% предлагаемой фазы на Хроматоне фракции 0,25 0 ,31 мм при скорости газа-носител Example. Separation was subjected to a mixture of tert-butylamine, sec-butylamine, nitromethane and butylamine on a 2 m column filled with 10% 1, 2,3-tris (/ 3-cyanethoxy) propane, and a column with 10% of the proposed phase on Chromatone fraction 0 25 0, 31 mm at speed of carrier gas
35 ют/мин и температуре колонок 120С.35 sp / min and column temperature 120C.
Как видно из приведенных на чертеже хроматограмм, на предлагаемой фазе (б) достигнуто полное разделение всех компонентов, в то врем As can be seen from the chromatograms in the drawing, in the proposed phase (b), a complete separation of all components is achieved, while
как на известной (а) втор.бутиламин (2) и нитрометан (3) разделены неполностью . Пики (1) и (4) на хроматограммах - соответственно трет.бутштамин и бутиламин.as on known (a) sec. butylamine (2) and nitromethane (3) are not completely separated. Peaks (1) and (4) on the chromatograms are tert.butstamine and butylamine respectively.
