General description
丙酮是极性有机溶剂。 在混合 TiO 2 -稀土氧化物存在下可发生光催化氧化。
Application
丙酮在 Mg-Al 层状双氢氧化物 (LDH) 作为催化剂，Cl - 和/或 CO 3 2- 作为补偿阴离子的存在下发生醛化反应，得到二丙酮醇和异亚丙基丙酮作为主要产物。在二肽催化剂存在下，其与各种靛红的对映选择性羟醛缩合形成 1-烷基 3-（2-氧丙基）-3-羟基吲哚-2-酮。丙酮水溶液可用作高锰酸钾氧化炔烃为 1,2-二酮的介质。
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。

[reaction: see text] The aldol condensation of acetone with several isatins is described. The desired compound was obtained in quantitative yield and with good enantioselectivities up to 77%. The best results were obtained with 10 mol % H-D-Pro-L-beta3-hPhg-OBn as a
Aldol condensation of acetone over layered double hydroxides of the meixnerite type.
