Title:
SOLVENTS FOR THE DETERMINATION OF AMINES IN WATER
Document Type and Number:
WIPO Patent Application WO/2012/042185
Kind Code:
A3
Abstract:
The invention relates to the use of non-volatile, non-toxic solvents for the spectrocolorimetry-based quantitative determination of organonitrogen compounds, particularly amines and derivatives, in any aqueous medium, replacing the chloroform normally used for the extraction of coloured complexes, in particular those formed with the aforementioned organonitrogen compounds and methyl orange, bromocresol purple and others.
