| Research on the Preparation Technology of ω-Bromide-p-hy-droxyacetophenone |
| LIU Can-ming. （College of Science; Hunan Agricultural Univresity; Changsha; 410128; China） |
| Abstract：A new approach to preparing ω-bromide-p-hydroxyace-tophenone was introduced through the reaction of p-hydroxyace-tophenone and liquid bromine using hydrobromicacid as catalyst and alcohol as solvent. In addition,The technological conditions as reaction temperature, reaction time, etc were explored, thus the cost of producton was brought down and technological operation was simplified. |
| Key words：Bromide-p-hydroxyacetophenone; preparation; catalyst |
