Nitrous acid reacts rapidly to conve ? the amino group of amino acids to a hydroxyl group: the volume of nitrogen liberated is used in the Van Slyke method [l] to estimate the number of primary amino groups present\_ This reaction was extended t.o the determination of primary amino groups in aromati
A simple and rapid method for the calorimetric determination of total nitrogen in coal has been tested on several coals digested under various conditions. The method consists of initial carbonization of the coal sample with H,SO, followed by digestion using continuous-flow addition of a mixture of 5
