WebIn this lab, you will nitrate your benzoic acid to 3-nitrobenzoic acid via electrophilic aromatic substitution. The Beach House, Thus, the theoretical amount of Toluene should have been 4,66g (about 5,4mL). If you wish to keep yours, add it to a flask with water. (LogOut/ All Stripes hll internationell bowlingturnering. r 2006 vergick freningen frn att vara en ishockeyfrening till en idrottsfrening fr att kunna omfatta flera sporter, och har sedan dess vuxit till att bli en av Sveriges strsta hbtqi idrottsfreningar och den strsta som erbjuder flera sporter. Having excess Toluene increases the contact area during reflux, decreasing reflux time. The desired conversion requires oxidation of toluene that can be achieved by any of the following means, as illustrated by the images. Meanwhile, set up an apparatus for Vacuum Filtration. Having excess Toluene prevents this because Toluene is oxidized much more easily. Your complete report for this experiment should include the data page, answers to the following questions, and a conclusion (1 page maximum. WebBenzoic Acid.
