Rapid and precise determination of nitroglycerin by the Schultze-Tiemann method

Abstract

An improved procedure for the quantitative determination of nitroglycerin by use of the Schultze-Tiemann method is described, in which the disadvantages of the previous procedure are avoided. Thus, time consumed in drying the residue from the ether extraction to constant mass (16–24 h), and in carrying out the oxidation process (30–60 min), is saved by omitting these two steps. The method is simple and its accuracy has been increased by carrying out the analyses on larger samples containing from about 50 to about 200 mg of nitroglycerin.
