Description
Изобретение-относитс к области aijajinтической химии, а именно, к способам количественного определени дибутилфосфорной кислоты и может быть использовано при контроле технологических процессов.The invention relates to the field of aijajintic chemistry, namely, to methods for the quantitative determination of dibutyl phosphoric acid and can be used in the control of technological processes.
Известен способ количественного определени дибутилфосфорной кислоты, заключающийс -в обработке анализируемой пробы метиленовым синим и хлороформом с последующим фотометрированием полученного раствора хлороформенного экстракта 1.A known method for the quantitative determination of dibutyl phosphoric acid, which consists in the processing of an analyzed sample with methylene blue and chloroform, followed by photometry of the resulting solution of chloroform extract 1.
Недостатком способа вл етс низка чувствительность определени .The disadvantage of this method is low detection sensitivity.
Наиболее близким к описываемому изобретению по технической сущности и достиraeMOiyiy результату вл етс способ количественного определени дибутилфосфорной кислоты в растворах трибутилфосфата в синтине , заключающийс в последов ательной обработке анализируемой пробы раствором сол ной кислоты, насыпхенным этилендиаминтетрауксусной кислотой, этилендиаминтетраацетатом натри и хлороформом, с последующим отделением водного сло и обработкой его феносафранином и хлороформом. The closest to the described invention according to the technical essence and the achievement of the MEOyiy result is a method for quantitative determination of dibutyltooltoccrystrate in tributylphosphate solutions in synthine, consisting in sequential processing of the sample being analyzed with a solution of hydrochloric acid, ethylenediaminetetraacetic acid, ethylenediaminetetraacetic acid, ethylene diaminetetraacetic acid, ethylenediaminetetraacetic acid, ethylenediaminetetraacetic acid, ethylenediaminetetraacetic acid, ethylenediaminetetraacetic acid, ethylenediaminetetraacetic acid, ethylenediaminetetraacetic acid, ethylenediaminetetraacetic acid, ethylenediaminetetraacetic acid, ethylenediaminetetraacetic acid, ethylenediaminetetraacetic acid, ethylenediaminetetra acetic acid, ethylenediaminetetraacetic acid, ethylenediaminetetraacetate acid and treating it with phenosafranin and chloroform.
отделении хлороформенного сло , добавлении приЭТОМ раствора 2.separation of the chloroform layer, adding at this solution 2.
Недостатком способа вл етс низка точность и плоха воспроизводимость результатов определени в присутствии продуктов сульфировани синтина - алкилсульфокислот и алкилсульфанолов, так как они по своим химическим свойствам близки к дибутилфосфорной кислоте и присутствуют в растворах в количествах соизмеримых с ней.The disadvantage of the method is low accuracy and poor reproducibility of the results of determination in the presence of sulfonation products of sintine - alkyl sulfonic acids and alkyl sulfanols, since their chemical properties are close to dibutyl phosphoric acid and are present in solutions in amounts commensurate with it.
Цель изобретени - повыщение точности и воспроизводимости определени в присутствии продуктов сульфировани синтина.The purpose of the invention is to increase the accuracy and reproducibility of the determination in the presence of sulfinated sintine products.
Поставленна цель достигаетс тем, что анализируемую пробу предварительно обрабатывают хлоридом бари и хлороформом при рН среды 5,45-5,55 с последующим отделением водного сло .The goal is achieved by the fact that the analyzed sample is pretreated with barium chloride and chloroform at a pH of 5.45-5.55, followed by separation of the aqueous layer.
