2'-히드록시-4'-메틸-5'-아세틸아세토페논 화학적 특성, 용도, 생산

• 제조 방법

  Preparation by cyclization of 1,1,3,3-tetraacetylpropene (formerly so called methenylbisacetylacetone) (SM) (m.p. 117–118°)
  , ? by adding a solution of SM (1 mol) in benzene to a sodium methoxide (4 mol)
  or magnesium methoxide (4 mol) solution in methanol and set aside for 24 h (quantitative yields)
  ; ? on heating of its potassium salt in alcoholic solution for 6–8 h at reflux. SM was prepared by treatment of ethoxymethyleneacetylacetone (m.p. 140–142°) with the potassium salt of acetylacetone in ethanol
