一般描述

丙酮是一种酮。据报道,在700℃或650℃下煅烧的TiO2 (P25) 与稀土氧化物(La2O3 or Y2O3)的混合物可有效地光催化丙酮的氧化。已有研究描述了在碱(Li,Na,K和Cs)或碱土(Ca,Sr和Ba)金属离子促进的MgO催化下,丙酮在气相中的醛醇缩合反应。在使用Mg-Al层状双氢氧化物(LDH)作为催化剂并使用Cl- 和/或CO32- 作为补偿阴离子时,丙酮可通过醇醛缩合反应,生成二丙酮醇和甲基异丁烯甲酮。已有研究描述了在二肽(催化剂)存在下,丙酮与各种靛红的对映选择性醇醛缩合。

应用

丙酮可用于以下研究:
  • 生物样品(血液)中葡萄糖代谢的NMR光谱评估。
  • 制备13wt%无定形聚乳酸(PLA)溶液,这是制备静电纺聚乳酸膜所必需的。
  • 作为在磺化氧化石墨烯-Pd/堇青石催化剂存在下合成甲基异丁基酮(MIBK)的前体。
  • 使用超临界流体(SCF)技术合成(4-羟甲基-2,2-二甲基-1,3-二氧环戊烷),一种甘油缩酮。
可用于合成以下丙酮腙:
  • 1-异亚丙基-2-甲基肼
  • 1-异亚丙基-2-羟乙基肼
  • 1-异亚丙基-2-甲酰肼
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。
适用于HPLC、分光光度法、环境测试
