Hydroquinone → 4-Methoxyphenol
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Hydroquinone | HCID 785 | — |
| Reactant | Triphenylphosphine | HCID 11776 | — |
| Reactant | Dimethyl Carbonate | HCID 12021 | — |
| Product | 4-Methoxyphenol | HCID 9015 | 97% |
Reaction Steps
22 parts of hydroquinone, 18 parts of dimethyl carbonate and one part of triphenylphosphine are kept for 15 hours at 190° C. Working up takes place as described in Example 23. 3 parts (97% of theory, based on converted hydroquinone) of hydroquinone monomethyl ether of boiling point 57° C. are obtained. The conversion is 12 percent.
