Reagents. Methods for determination of parent substance of organic nitrogen bearing compounds and salts of organic acids
Реактивы. Методы определения основного вещества азотсодержащих органических соединений и солей органических кислот
Status: Not effective - Superseded. Registration information 1669-st dated 10.11.2016 (official website of Rosstandart); IUS 6-2017
The standard applies to organic reagents and establishes the following methods for determining the basic substance of nitrogen-containing compounds and salts of organic acids: the method of titration in a non-aqueous medium - in the analysis of weak bases (amines, organic acids, salts of organic bases, amino acids, amino alcohols); diazotization method - in the analysis of aromatic amines and other nitrogen-containing compounds after their preliminary reduction to amines; Kjeldahl method - in the analysis of various classes of nitrogen-containing compounds.
Стандарт распространяется на органические реактивы и устанавливает следующие методы определения основного вещества азотсодержащих соединений и солей органических кислот: метод титрования в неводной среде - при анализе слабых оснований (амины, солиорганических кислот, соли органических оснований, аминокислоты, аминоспирты); метод диазотирования - при анализе ароматических аминов и других азотсодержащих соединений после их предварительного восстановления до аминов; метод Кьельдаля - при анализе различных классов азотсодержащих соединений.
