Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Diethyl Ether | HCID 3283 | — |
| Reactant | Acetic Anhydride | HCID 7918 | — |
| Reactant | Cyanamide, (methylenedi-4,1-phenylene)bis- | HCID 169119 | — |
| Product | HCID 20153940 | HCID 20153940 | — |
Reaction Steps
124.1 g (0.5 mol) of 4,4'-methylene-bis-(phenylcyanamide) and 510.5 g (1.0 mol+400% excess) of acetic anhydride are reacted at 73°-83° C. for 4 hours and 10 minutes, 465 ml of diethyl ether are then added and the mixture is cooled. The suspension is filtered with suction and the residue is dried at 50° C. in vacuo to give 139.6 g (84.0% of theory) of a crystalline product which, after recrystallisation from toluene, has a melting point of 134°-136° C.
