VERSATILE COMPOUND OFFERING INTERESTING POSSIBIUTIES AS A CHEMICAL INTERMEDIATE
fcEACTlOHS * SuÎDstitutions can be made in the imino and car-
borayl groups· Φ Fission of the ring is possible with mineral acids
ancl dilate alkali solutions. ·* Mono- and di-N-halogen derivatives are secured
by nalogenation. · • Reactions with formaldehyde yield a variety of
compounds, including methylol derivatives and a eerâes of resins varying from viscous, oily liquids to liard, brittle, transparent solids. These resins aret soluble in water, yielding low viscosity solutionis which dry to hard, glossy films·
