Newly discovered organic reactions
WebThe newly formed extra-framework aluminum was found to be responsible for the high catalytic activity. BET analyses showed that the surface area drops at higher calcination temperatures. This leads to a lower catalytic activity for most known reactions. However, for this study, no decrease in activity has been observed. WebChlorinated ethenes are ubiquitous groundwater contaminants posing a threat to one of our main drinking water sources. Despite their spill history dating back to more than 40 years ago, these contaminants are still found in groundwater in numerous industrially developed countries due to their persistence, difficult characterisation in the subsurface and …

WebHe found two basic forms: in one, the rate of the reaction depended on the concentration of both the nucleophile and the organic molecule it was attacking. In the other, however, increasing the concentration of the nucleophile made no difference to the reaction rate, which only depended on the concentration of organic substrate.
