со эо со ческой химии, а именно к способам определени воды, и может быть использовано дл определени воды в предельных углеводородах. Цель изобретени - распшрение функциональной возможности способа на область предельных углеводородов. Пример . Ампулы, припа нные к реактору, содержат раствор этилалюминийдихлорида в предельном углеводороде с концентрацией 1,6-10 моль/л анализируемый предельный углеводород 1 .мл, бензол 1 МП. Реактор вакуумируетс до Ю торр, после чего отпаиваетс от вакуумной . спуст 3 мин производ т запись спекгра . Измер ют оптическую плотность и по калибровочному графику определ ют содержание воды в анализируемом предельном углеводороде. Вместо бензола могут быть использованы его гомологи - мезитилен , толуол, ксилол и jip. Предел обнаружени составл ет 8,1-10 мкг. Способ позвол ет определ ть воду в диапазоне концентраций 10 - 10 моль/л, Примеры определени воды в других органических растворител х приведены в таблице,it can be used to determine water in saturated hydrocarbons. The purpose of the invention is to expand the functionality of the method to the region of saturated hydrocarbons. An example. The ampoules attached to the reactor contain a solution of ethyl aluminum dichloride in a limiting hydrocarbon with a concentration of 1.6-10 mol / l of the analyzed limiting hydrocarbon 1. Ml, benzene 1 MP. The reactor is evacuated to 10 Torr, after which it is sealed from the vacuum. After 3 min, the recording of spekgra was made. Optical density is measured and the water content of the analyzed saturated hydrocarbon is determined from a calibration graph. Instead of benzene, its homologs can be used - mesitylene, toluene, xylene and jip. The detection limit is 8.1-10 µg. The method allows the determination of water in a concentration range of 10 - 10 mol / l. Examples of the determination of water in other organic solvents are given in the table.
Из табличных данных следует,.что предлагаемый способ вл етс точным и применим дл определени воДы вFrom the tabular data it follows that the proposed method is accurate and applicable to the determination of water in
широком диапазоне органических растворителей предельного р да .a wide range of organic solvents of the limiting range.
