Marqueyrol [74] reported experiments carried out in France over a period of 15 years to compare the efficiency of various stabilizers. The results are shown in Table 175. In addition to amyl alcohol and diphenylamine, the action of N-nitrosodiphenyl-amine (diphenylnitrosamine), carbazole, diphenylbenzamide, nitronaphthalene and naphthalene was also tested. The powder was stored at temperatures of 40, 60 or 75°C. The experiments were stopped when the powder showed signs of intense decomposition, giving off nitric oxides. This was also manifested by a sudden fall pf the nitrogen content in nitrocellulose isolated from the samples.
