CHEMICAL ANALYSIS OF A MAGNESIUM-SODIUM NITRATE COMPOSITION IN A LAMINAC BINDER
Abstract
A scheme for the chemical analysis of an illuminant composition of Mg, NaNO3, and laminac 4110 binder is described. NaNO3 is removed by water extraction and treated, under an inert atmosphere, with FeCl2 and 12 N HCl. The ferric ion formed in this reaction is then titrated with standard 0.2 N TiCl3 solution. Mg is removed with dilute HCl and determined by titration with 0.1 M EDTA solution. Laminac binder is determined from the sum of the volatiles and the residue remaining after the extraction of NaNO3 and subsequent removal of Mg. The presence of Co due to cobalt naphthanate is detected by the orange color developed in the presence of 1-nitroso2-naphthol. (Author)
