General description
据报道，TiO2 (P25) 与稀土氧化物的混合物对丙酮的氧化反应具有光催化活性。已经研究了碱金属（Li、Na、K和Cs）或碱土金属（Ca、Sr和Ba）离子在MgO上促进丙酮的气相醇醛缩合反应。在存在催化剂Mg-Al层状双氢氧化物（LDH）并且以Cl-和/或CO32-作为补偿阴离子的条件下，丙酮发生醇醛缩合反应，生成双丙酮醇和亚异丙基丙酮。已有研究描述了丙酮与几种靛红的对映选择性醇醛缩合反应。
Application
丙酮是用于紫外光谱的合适试剂。它可用于以下研究：
- 作为一种有机溶剂，用于研究TiO2和Al2O3 粉末的Zeta电位。
- 用于合成聚原酸酯（POE），一种可生物降解的载体，适用于药物递送装置。
- 用于对脂质中的酯基进行分光光度法测定。
丙酮的发光强度取决于溶液组分。丙酮吸收UV光，导致丙酮光分解和放射性产物。
