Epichlorohydrin → 1-(2,3-Epoxypropoxy)-4-(2-hydroxyethoxy)benzene
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Epichlorohydrin | HCID 7835 | — |
| Reactant | Potassium Carbonate | HCID 11430 | — |
| Reactant | 4-(2-Hydroxyethoxy)phenol | HCID 9834014 | — |
| Product | 1-(2,3-Epoxypropoxy)-4-(2-hydroxyethoxy)benzene | HCID 20151309 | — |
Reaction Steps
With stirring, 13 g of crude 4-(2-hydroxyethoxy)phenol, 35 m of epichlorohydrin and 23.5 g of potassium carbonate are heated for 11/2 hours to reflux temperature. The reaction mixture is filtered and the filtrate is concentrated by evaporation under reduced pressure. The residual oil gradually congeals to a crystalline solid, which is recrystallised from isopropanol, affording 1-(2,3-epoxypropoxy)-4-(2-hydroxyethoxy)benzene with a melting point of 65°-67° C. Working up of the mother liquor yields further crystalline product.
