2-Chloro-2-phenylacetophenone for synthesis - Reference Information
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| uses | organic intermediates. |
| production method | dissolve benzoin in hot pyridine, then cool and solidify, slowly add sulfoxide chloride after crushing, stir vigorously, and keep cool. A large amount of sulfur dioxide and hydrogen chloride escape during the reaction. The reaction product is washed with water, filtered and dried, and recrystallized with ethanol to obtain diphenylchloroethyl ketone. |
