Abstract

Using nanodiamonds of the UDD-STP brand 1 wt % palladium-containing nanodiamonds are obtained and tested as catalysts of tetrachloromethane hydrodechlorination under mild conditions (solvents, ethanol and methanol; Т = 298–318 K; \({{P}_{{{{{\text{H}}}_{2}}}}}\) = 0.1 MPa). The catalytic properties of the obtained material and a palladium-containing analog based on activated carbon are compared. It is shown that the hydrodechlorination reaction occurs in a stepwise manner via two pathways: to form products with a smaller content of chlorine, for example, chloroform, and to yield oxygen-containing products, for example, diethyl carbonate. The qualitative and quantitative compositions of reaction products are determined by gas chromatography/mass spectrometry.

含钯纳米金刚石上的四氯甲烷加氢脱氯

摘要

使用UDD-STP品牌的纳米金刚石，获得了1 wt％的含钯纳米金刚石，并在温和条件下（溶剂，乙醇和甲醇；Т = 298-318 K；Т = 298–318 K；\（{{P} _ {{ {{{\ text {H}}} _ {2}}}}} \） = 0.1 MPa）。比较了所获得的材料和基于活性炭的含钯类似物的催化性能。已表明加氢脱氯反应是通过两个途径逐步进行的：形成氯含量较低的产物，例如氯仿，以及生成含氧产物，例如碳酸二乙酯。通过气相色谱/质谱法确定反应产物的定性和定量组成。
