Капролактам технический. Определение перманганатного числа. Спектрометрический метод
Название (англ.):
Caprolactam for industrial use; determination of permanganate index; spectrometric method
Описание (англ.):
Equal volumes of potassium permanganate solution are added to a carpolactam test solution and to a blank (water). After standing for a specified time the absorbance, at a wavelength of 420 nm, of the test solution and of the blank are compared in cells of 5 cm thickness. The permanganat index is the difference between the absorbance of the test sample and that of the blank, multiplied by 100/3. It is a conventional measure of thecontent of oxidizable impurities.
