The interest and work on guanidine and its dreivatives in the past decade has been greatly stimulated by their increased uses. Of its deriviatives, nitro-guanidine is of peculiar interest, both technically and scientifically. The compound is an explosive and for this reason many practical applications can be found for it. Since it may be prepared from dicyandiamde, a derivative of lime-nitrogen (calcium cyanamide), the essential raw materials for which are nitrogen of the air and limestone, the potential supply is unlimited. It is important scientifically, for from it aminoguanidine, hydrazine, dyronitiric acids, and other products, may be obtained from its reduction. As an example of the use of these compounds, aminoguanidine is being diazotized and hot-coupled with various intermediates to furnish a while new series of azo dyes which possess good dyeing properties on animal fibers.
