H. Kunz-Krause4) investigated this compound more closely. He comes to the conclusion that it is not a uniform body, but is composed of allylamine sulphate, soluble in water, and ^.semfo-sulphocyanogen, insoluble in water. In addition to these two chief compounds, there are present most likely small quantities of xanthogenic acid derivatives, iso-sulphocyanic acid and allyl- substituted urea. As the constituent of the deposit which could be washed out with water, smelled distinctly of mustardseed oil, after having been stored over caustic lime for several months, the author thinks that the insoluble part decomposes and splits off allyl mustard oil. It is probable that a solid polymeride of iso-sulphoallyl cyanide (S = C = N — C3H5)n forms, perhaps in combination with ^sewdo-sulphocyanogen, C3HS3N3, formerly called per-sulpho-cyanogen5). The author gives as the reason for the formation of the deposit and of the other accessory compounds always present in mustardseed oil, the decomposition of three molecules of mustardseed oil in sulphur and allyl cyanide, and certain intramolecular changes of the mustardseed oil, due to *) Cf.
