- Abstract
- The condensation of methyl N-phenylcarbamate with HCHO to methylene diphenyl diurethane has been studied in a batch reactor in the presence of cation exchanged resins. Unlike conventional H2SO4 catalyst, fresh resin catalysts did not form a byproduct N-benzyl compound. However, accumulation of water from repeated uses of the catalyst caused a decreased activity and the formation of the byproduct. The deactivated catalyst could be completely regenerated by drying in vacuo. Ethylacetate and toluene were found to be efficient solvents with the resin catalysts. © 1991
