The reaction of cyclohexylamine with urea under solvent-free condition is discussed. The one-step and one-pot synthesis via transamination for industrial production is studied where, cyclohexylamine is heated with urea to give desired product dicyclohexylurea (DCU) in molar yield. In the experiment, the researchers used many compounds, for example, 1,3-Dicyclohexylurea (cas: 2387-23-7Product Details of 2387-23-7).
1,3-Dicyclohexylurea (cas: 2387-23-7) belongs to amides. Amides are pervasive in nature and technology. Proteins and important plastics like Nylons, Aramid, Twaron, and Kevlar are polymers whose units are connected by amide groups (polyamides); these linkages are easily formed, confer structural rigidity, and resist hydrolysis. Amides are not in general accessible by the direct condensation of amines with carboxylic acids for two reasons: first, both components are readily deactivated by a transfer of a proton from the acid to the amine and second, the hydroxy unit on the carbonyl of the acid is a relatively poor leaving group. Nevertheless, the formation of five- and six-membered rings is often surprisingly simple provided that other factors can be brought into play to assist in the condensation.Product Details of 2387-23-7
