Several residues, formed by the spontaneous oxidation of a number of amine hydrosulfides, had been standing in open tubes for eight months. The residue from n-butylamine hydrosulfide was large in comparison with the others at hand. Recrystallization of this product from water yielded a white crystalline compound which began to sublime at 175" and melted with decomposition and charring at 180-193'. Analysis for nitrogen and ...
