DIMETHYL HYDANTOIN

A VERSATILE COMPOUND OFFERING INTERESTING POSSIBILITIES AS A CHEMICAL INTERMEDIATE

FACTIONS ® Substitutions can be made in the imino and car-

bonyl groups. ® Fission of the ring is possible with mineral acids

and dilute alkali solutions. ® Mono- and di-N-halogen derivatives are secured

by halogenation. • Reactions with formaldehyde yield a variety of

compounds, including methylol derivatives and a series of resins varying from viscous, oily liquids to hard, brittle, transparent solids. These resins are soluble in water, yielding low viscosity solu­tions which dry to hard, glossy films.
