overview	2,2, 2-triphenylacetophenone can be used as an intermediate in pharmaceutical synthesis. If 2,2, 2-triphenylacetophenone is inhaled, please move the patient to fresh air. If skin is in contact, remove contaminated clothes, rinse the skin thoroughly with soapy water and clear water, and see a doctor if you feel uncomfortable.
production method	1. preparation method: add 1g iodine, 500mL glacial acetic acid, phenyl pinacol (2)100g(0.27mol) to a 1L round bottom flask equipped with reflux condenser. Under shaking, slowly heat to boiling, about 5min the solid dissolves, forming a red solution. Immediately transfer the reaction solution to a 1L beaker, cool, precipitate solid, filter, glacial acetic acid wash 2-3 times, until colorless, dry, almost pure compound (1), weight 90-91g, yield 95%-96%,mp178 -179 ℃. Dissolve it in 450mL of hot benzene, filter, add 250mL of petroleum ether (90~100 ℃), cool, filter and dry to obtain pure product (1)82~83g,mp179~180 ℃ [1]
