Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Cyclohexylamine | HCID 7965 | — |
| Reactant | Methyl Isocyanate | HCID 12228 | — |
| Solvent | Diethyl Ether | HCID 3283 | — |
| Product | 1-Cyclohexyl-3-methylurea | HCID 308344 | 67.3% |
Reaction Steps
In 500 ml of ethyl ether is dissolved 57 g of methyl isocyanate and, then, 99 g of cyclohexylamine is added dropwise, whereupon crystals separate. The crystals are washed with ether. By the above procedure is obtained 105 g of N-methyl-N'-cyclohexylurea. melting point: 160°-161° C.
