Claims
- 1. A process for preparing 1,3-(dihydroxy)-4-(acetylor propionyl)benzene, which comprises combining resorcinol with a) acetic acid or propionic acid, respectively, and b) hydrobromic acid at a temperature between about the boiling point of the reaction mixture to about 75.degree. C. for between about one hour to about five days.
- 2. A process of claim 1, wherein 1,3-dihydroxy-4-acetylbenzene is prepared by combining resorcinol with acetic acid and hydrobromic acid at a temperature between about the boiling point of the reaction mixture to about 75.degree. C. for between about one hour to about five days.
- 3. A process of claim 2, wherein the temperature is from between about 80.degree. C. and about 90.degree. C.
- 4. A process of claim 3, wherein the reaction mixture contains hydrogen bromide gas that has been dissolved in the glacial acetic acid.
