Пример 2. К навеске амина (0,05 г) в мерной колбе емкостью 50 мл добавл ют до метки хлороформ. Из полученного раствора отбирают пипеткой определенное количество аминаи перенос т в калиброванные на 10 мл пробирки с притертыми пробками. Добавл ют 0,7 мл 0,25%-ного раствора дибепина-3 в абсолютном диоксане, 5 мл хлороформа и по капл м, перемешива , 1 мл метилового спирта, насыщенного КзСОз. Затем содержимое пробирки довод т метиловым спиртом до 10 мл.Example 2. To a portion of the amine (0.05 g) in a 50 ml volumetric flask, chloroform was added to the mark. From the resulting solution, a certain amount of amines are pipetted and transferred to ground test tubes calibrated with 10 ml. 0.7 ml of a 0.25% solution of dibepin-3 in absolute dioxane, 5 ml of chloroform and dropwise, stirring, 1 ml of methyl alcohol saturated with CsSO3 are added. The contents of the tube are then made up to 10 ml with methyl alcohol.
Оптическа плотность растворов измен етс па фотоэлектрокодориметре ФЭК56М с желтым светофильтром в кювете длиной 10 мм. Растворы, содержащие 2,5- 20 мкг/мл октадедиламина, подчин ютс закону Ламберта-Берта.The optical density of the solutions is varied by a FEK56M photoelectrocodorimeter with a yellow light filter in a 10 mm long cuvette. Solutions containing 2.5-20 µg / ml octadedylamine are subject to the Lambert-Bert law.
В качестве раствора сравнени готов т холостую пробу, дл чего в пробирку на 10 мл внос т 0,7 мл 0,25%-иого раствора 15 мл хлороформа, 1 мл метанола, насыщенного К.2СОз. Содержимое пробирки довод т до 10 мл метиловым спиртом, перемешивают и перенос т в соответствующие кюветы . Содержание аминов в анализируемых пробах наход т по калибровочному графику .A blank sample is prepared as a comparison solution, for which 0.7 ml of a 0.25% solution of 15 ml of chloroform, 1 ml of methanol saturated with K 2 CO 3 are introduced into a 10 ml test tube. The contents of the tube are made up to 10 ml with methyl alcohol, mixed and transferred to the appropriate cuvettes. The content of amines in the analyzed samples is found on the calibration graph.
При определепип первичных аминов с помощью дибепина-3 чувствительность определени повышаетс в 4 раза - 2,5- 20 мкг/мл.With the definition of primary amines using dibepin-3, the detection sensitivity is increased 4 times - 2.5-20 µg / ml.
