Description
Изобретение относитс к аналити- ческой химии, а именно к исследованию и анализу материалов с помощью оптических методов и, в частности, к способам количественного определени состава смесей углеводородных топлив.The invention relates to analytical chemistry, namely to the study and analysis of materials using optical methods and, in particular, to methods for quantitative determination of the composition of mixtures of hydrocarbon fuels.
Целью изобретени вл етс повышение точности определени концентрации остаточного топлива в области малых (Ojl-ljO Mac.%j значений.The aim of the invention is to improve the accuracy of determining the concentration of residual fuel in the region of small (Ojl-ljO Mac.% J values.
Физической основой способа вл етс экспериментально установленный факт различи величин соотношени оптических плотностей на длинах вол 440 и 600 нм в дистилл тных топлива не содержащих примесей остаточных топлиБ, и в смес х дистилл тных топлив с остаточными топливами. Это обусловлено повышенной оптической активностью на длине волны 600 нм в ществ 5 вход щих в состав остаточных топлив.The physical basis of the method is the experimentally established fact of the difference in the values of the ratio of optical densities at wavelengths of 440 and 600 nm in distillate fuels that do not contain residual topliB and in mixtures of distillate fuels with residual fuels. This is due to the increased optical activity at a wavelength of 600 nm in the substance of 5 residual fuels included in the composition.
П р и м е р. Испытано 3 вида дистилл тных топлив: реактивное (ТС-1 по ГОСТ 10227-62), дизельное (Л по ГОСТ 305-82) и газотурбинное (ТГВК по ГОСТ 10433-75), т.е. весь диапазон используемых дистилл тных топлив , Оптическую плотность их повышали путем добавлени мазута Ф-5 по ГОСТ 10585-75, а в образцах без мазута - окислением в процессе хранени до различной глубины. Топлива перед определением оптической плотности (на кювете с рабочим рассто нием 5 мм) фильтровали на мембранном фильтре с размером пор 0,3 мкм.PRI me R. Three types of distillate fuels were tested: reactive (TS-1 according to GOST 10227-62), diesel (L according to GOST 305-82) and gas turbine (TGVK according to GOST 10433-75), i.e. the whole range of distillate fuels used, their optical density was increased by adding F-5 fuel oil according to GOST 10585-75, and in samples without fuel oil — by oxidation during storage to different depths. Before determining the optical density of the fuel (on a cell with a working distance of 5 mm), it was filtered on a membrane filter with a pore size of 0.3 μm.

При содержании в топлкше мазута в количестве не менее 0,07-0,10 мас,% (дл разных видов топлива отношение составл ет 10,0 и менее,The rfs of the data presented shows that at approximately equal values of the ratio for fuels containing fuel oil, less than for fuels without fuel oil, than values greater than 2.0 (gas turbine fuel with 0.960). When the amount of fuel oil in the fuel is not less than 0.07-0.10 wt.% (For different types of fuel, the ratio is 10.0 or less,
Использование ,дл измерений меньших ( нм) и больших () - длин волн в сравнении с выбранными (440tlO и 600110 нм) снижает чувствительность метода. В обоих случа х присутствие мазута в количестве Qj07 мас.% не обнаруживаетс .Using, for measuring smaller (nm) and large () - wavelengths in comparison with the selected (440tlO and 600110 nm) reduces the sensitivity of the method. In both cases, the presence of fuel oil in the amount of Qj07 wt.% Is not detected.
