The isomeric transformation of urea into ammonium cyanate in aqueous solutions

Abstract

Walker & Hambly (1895) showed that the isomeric transformation of ammonium cyanate into urea (Wohler, 1828) was spontaneously reversible in aqueous solutions. At equilibrium at 1000, a 0-lM- solution of urea was said to contain approximately 95 % urea and 5% ammonium cyanate. Werner
