说明

General description

TiO ₂ (P25) 与稀土氧化物（La₂O₃ or Y₂O₃）的混合物在 700°C 或 650°C 煅烧可有效地引起丙酮的氧化。研究了碱金属 (Li、Na、K、Cs) 或碱土金属 (Ca、Sr、Ba) 促进的 MgO 在气相中的羟醛缩合反应。在 Mg-Al 层状双氢氧化物 (LDH) 作为催化剂，Cl ^- 和/或 CO₃^2- 作为补偿阴离子的存在下发生羟醛缩合反应，生成二丙酮醇和异亚丙基丙酮。研究了二肽（催化剂）存在下丙酮与各种靛红的对映选择性羟醛缩合反应。

Application

丙酮已被用于制备 13wt% 无定形聚乳酸 (PLA) 溶液，这是制备电纺 PLA 膜所需的。

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。

Screening for Estrogen Active Nonylphenols in Water by Planar Solid Phase Extraction – Planar Yeast Estrogen Screen

Nonylphenols (NP) are ubiquitous substances that have been detected in highly diverse foodstuff. As breakdown products of nonylphenol ethoxylates, NP could end up in the aquatic environment. This article presents a rapid method for NP detection in surface water by planar solid phase extraction – planar yeast estrogen screen (pSPE-pYES).
