Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Formaldehyde | HCID 712 | — |
| Reactant | Urea | HCID 1176 | — |
| Reactant | Melamine | HCID 7955 | — |
| Product | Melamine urea | HCID 21896498 | 96% |
Reaction Steps
Melamine (63 parts), 180 parts of urea and 629 parts of 37.2% formalin were reacted at a pH of 10.3. The reaction mixture was dehydrated under reduced pressure to give about 640 parts (yield about 96%) of a melamine urea cocondensate resin having an involatile content of 70 %.
