Abstract：Diacetone alcohol (DA) was synthesized by means of alcohol condensation reaction in a continuous fixed bed reaction vessel designed by authors. The refractive index and IR of the product were determined and characterized. The reaction temperature, catalysts, catalyst lifetime and its filling patterns were discussed. The results showed that the continuous fixed bed reaction vessel could be applied effectively to the synthesis of DA, and the reaction temperature, the catalyst varieties and theirs filling patt...
