Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Formaldehyde | HCID 712 | — |
| Reactant | Resorcinol | HCID 5054 | — |
| Reactant | Sodium Sulfate | HCID 24436 | — |
| Solvent | Water | HCID 962 | — |
| Product | Resorcinol-formaldehyde resin | HCID 159980 | — |
Reaction Steps
Resorcinol, excess formaldehyde, and sodium sulphate were dissolved in water and heated with stirring on a water bath. As soon as the solution became cloudy, the reaction was terminated by the addition of a large volume of cold water. The precipitate was filtered off, washed with water, and dried at room temperature.
