The authors had given, in their previous paper, the optimum conditions for the decomposition of N-methyl compounds into methyl iodide in hydroiodic acid in the microdetermination of N-methyl group with volumetric finish. In this paper, more sophisticated methods with gravimetric finishes using solid absorbents were investigated in place of the volumetric finish. Measurement of the weight increase of the heated silver granules caused by the absorbed iodine, which had been given after the combustion of methyl iodide, was prefered to give satisfactory results in a routine analysis, while that of the molecular sieve 13-X resulted by the absorbed methyl iodide required a further investigation concerning significantly high(+) error with certain compounds.
