| biological activity | Paroxypropione is an artificial, non-steroidal estrogen that is used medically as an anti-gonadotropin. |
| Application | used as liquid crystal raw materials and intermediates |
| production method | add anhydrous aluminum trichloride to carbon disulfide, stir, add phenyl propionate Dropwise, the reaction takes place immediately and releases hydrogen chloride, the carbon disulfide was refluxed due to the exotherm of the reaction. Upon completion of the dropwise addition, the reaction mixture was heated at reflux for 2H until hydrogen chloride did not escape. In addition to steam carbon disulfide, heating to 140-150 deg C for 3H, and the release of hydrogen chloride. The resulting resin-like substance was cooled, and hydrochloric acid and water were slowly added to decompose the double salt of aluminum. It was placed in a refrigerator overnight, filtered, and the filter cake was recrystallized from methanol to give P-hydroxyphenylacetone in 34-39% yield. |
