The kinetics of the alkylation of 2-alkylindan-1,3-diones by benzyl bromide has been studied in microemulsions and polar organic solvents. In microemulsions the reaction proceeds at the microscopic water/oil interface. The solvent properties of this interfacial environment are assumed to be similar to those of methanol. In order to describe the kinetics of reactions occurring in microemulsions stabilized by non-ionic amphiphiles, the volume of the microemulsion is divided into three regions: water-rich, oil-rich and interfacial regions. The interfacial region is treated as a two-dimensional interface or as an interfacial volume.
在微乳液和极性有机溶剂中研究了苄基溴对 2-烷基茚满-1,3-二酮的烷基化动力学。在微乳液中,反应在微观的水/油界面上进行。这种界面环境的溶剂特性被假定为与甲醇相似。为了描述由非离子两性化合物稳定的微乳液中发生的反应动力学,微乳液的体积被分为三个区域:富水区、富油区和界面区。界面区被视为二维界面或界面体积。
