However, the bottleneck in many of these solid-phase reactions is the reaction rate. In all but 1 of the 24 examples reviewed above, microwave heating reduced the reaction time for solid-phase combinatorial synthesis from hours/days to minutes. These rate reductions are speculated to arise from...
Catalysis is the process of increasing the rate of a chemical reaction by adding a substance known as a catalyst. Catalysts remain ( ) after the reaction.() A. increased B. reduced C. unchanged D. unknown 相关知识点: 试题来源: 解析 C ...

Optimum emulsion reassociation rates are obtained by vigorous shaking of the emulsion. At high DNA concentrations the rate depends on the violence of shaking. The fragment size of the DNA used in the emulsion reaction does not greatly influence the rate of reassociation. DNAs from viruses, ...

The catalyst [10]NTf2 was fastest among the three new catalysts, but also this catalyst showed a rate of reaction that was slightly slower than [3]NTf2. The cyclization rate exhibited by [9]PF6 was the slowest although its analogue [9]NTf2 showed roughly a four-fold increase in the ...

? 2021 Elsevier B.V.Aiming at improving the activity of supported catalysts toward oxidative desulfurization (ODS) reaction, an increasing support utilization rate strategy is developed by introducing additional phosphotungstic acid (HPW) on V anchored zeolite SiBeta. Both the Keggin HPW on the surfac...
In recent years two cognitive models of schizophrenic dysfunction have been elaborated which involve the basic proposition that schizophrenic patients process information at a slower rate than non-schizophrenic controls (McGhie, 1965; Yates, 1966). Both models predict (1) that schizophrenic patients wil...
