Description
Изобретение относитс к области исследовани химических и.физических свойств веществ и касаетс газохроматографического. разделени олесей органических веществ. Известно применение в качестве неподвижны фаз дл газовой хроматографии более 900 наименований органических и Н1еоргакических соединений 1. Из фосфороорганических соединений известно применение в качестве неподвижных фаз дл газовой хроматографии окисей третичных фосфинов общей формулы ( (0)CH(ftKMiClO)y,R, где , йгСН С-СМд ; ,S а также окисей третичных фосфинов, содержащих нитрильнь е группы формулы р- , где R, R - этил, фенил, 2-цианэтнл; Ri - 2-цианэтил, 2-ЦианпрЬпил 12. Однако указанные неподвижные фазы обладают недостаточно высокой селективностью раз делени ароматических углеводородов от нитросоединений . Целью изобретени вл етс вы вление вещества , которое можно применить в качестве неподвижной фазы, обладающей высокой раздел ющей способностью ароматических: углеводородов к нитропарафинов. Эта цель достигаетс тем, что в качестве неподвижной фазы дл газовой хроматографии дл разделени ароматических углеводородов и нитропарафииов примен ют эфирофторангидриды -стирилфосфоновой кислоты общей формулы OR..

Ранее эфирофторангидрищ 1 в качестве неподвижных фаз дл газовой хроматографии не примен лись . Пример. Эфирофторангидриды нанос т на инертный или активный носитель в количестве до 25 мас.% от массы носител и полу387This invention relates to the field of chemical and physical properties of substances and concerns gas chromatography. separation of organic matter. It is known to use as stationary phases for gas chromatography more than 900 names of organic and organic compounds 1. Among organophosphorus compounds it is known to use tertiary phosphines of the general formula ((0) CH (ftKMiClO) y, R, where C-SMd ;, S as well as oxides of tertiary phosphines containing nitrile groups of the formula p-, where R, R is ethyl, phenyl, 2-cyanoethyl; Ri is 2-cyanoethyl, 2-Cyanpryl 12. However, these stationary phases have insufficient high selectivity pa separation of aromatic hydrocarbons from nitro compounds. The aim of the invention is to identify a substance that can be used as a stationary phase, having a high separating ability of aromatic hydrocarbons to nitroparaffins. This goal is achieved by the fact that as a stationary phase for gas chromatography for the separation of aromatic hydrocarbons and nitroparaphoses are used ether-styrylphosphonic acid of general formula OR .. C HjOH cHPxp / where RzCHj, C, H.,. -. ° Said compounds are obtained by treating p-styryltetrafluorophosphorane with alcohols in carbon tetrachloride. Previously, the ether fluorofluorine 1 was not used as stationary phases for gas chromatography. Example. Efiroftorangidridy applied to an inert or active carrier in an amount up to 25 wt.% By weight of the carrier and semi387

Оценка селективности неподбижных фаз в пределах разных гомологических р дов осуществл етс на основе разницы между факторами пол рности Х-бензол, Y-зтанол, Z-метилзтилкетон , И-нитрометан, S-пиридин.The evaluation of the selectivity of the unsuitable phases within different homologous series is carried out on the basis of the difference between the polarity factors X-benzene, Y-ethanol, Z-methyl-methyl ketone, I-nitromethane, S-pyridine.
В табл. 1 приведены значени факторов пол рности и их разности предложенной неподвижной фазы в сравнении с известной, Из таблицы 1 видно, что наиболее высока селективность наблюдаетс при разделении на за вл емой фазе ароматических углеводородов и нитропарафинов , поскольку велишна разностиIn tab. Table 1 shows the values of the polarity factors and their difference between the proposed stationary phase and the known one. From Table 1 it can be seen that the highest selectivity is observed in the separation of aromatic hydrocarbons and nitroparaffins on the claimed phase, since the difference is
(И-X) у них наибольша (3,60 и 3,64) (табл. 1, фазы 2 и 3).(I-X) they have the highest (3.60 and 3.64) (Table 1, phases 2 and 3).
Данные табл. 2 показьшают, что наиболее высокие значени констант Роршнайдера наблюдаютс дл метилэтилкетона (Z) и нитрометана (и), а величина разности констант Роршнайдера наибольша при разделении нитросоединений и ароматических углеводородов.. Дл неподвижной фазы № 2 (см. таблицу) эта разность составл ет 365 единиц.The data table. 2 shows that the highest values of the Rorschneider constants are observed for methyl ethyl ketone (Z) and nitromethane (and), and the difference of the Rorschneider constants is greatest when separating nitro compounds and aromatic hydrocarbons. For the stationary phase No. 2 (see table), this difference is 365 units.
Таким образом, при разделении нитросоединений и ароматических углеводородов предложенна неподвижна фаза имеет существенные преимущества в части селективных свойств.Thus, in the separation of nitro compounds and aromatic hydrocarbons, the proposed stationary phase has significant advantages in terms of selective properties.
Приведенные примеры показывают, что предлагаема неподвижна фаза вл етс более селективной при разделении ароматических угле-, водородов от нитропарафинов и позтому может найти самое широкое применение.The examples given show that the proposed stationary phase is more selective in the separation of aromatic carbons, hydrogens from nitroparaffins, and therefore it can find the widest application.
