the use of ion-exchange resin in the reaction (synthesis of ethyl acetate by fischer esterification)
Hello! Could you please draw the generic mechanism for Fischer esterification for the synthesis of benzocaine from p-aminobenzoic acid and ethanol catalysed by conc. H2SO4 and if it is possible explain steps Thank you so much!
Describe the relative advantages and disadvantages of convergent vs divergent dendrimer synthesis.
Fischer esterification lab question, Please help. Thank you in advance 1) In the synthesis of isopentyl ethanoate, whose reaction is shown below a) what is the purpose of the sodium bicarbonate solution in the isolation step? b) what is the purpose of adding molecular sieves to the reaction? c) what is the purpose adding sulfuric acid to the reaction? d) why is acidic acid added in excess? e) what is the purpose of conducting a semi-micro distillation in the second...

Ester Synthesis In today's lab, you will perform small scale Fischer esterifications to make a variety of esters. H2SO4 R OH + R'OH = ROR' Combinatorial chemistry is a term used to describe small scale reactions, where in a large number of different molecules can be made using the same reaction conditions, by varying the reactants. In the case of Fischer esterifications, one can vary the carboxylic acid and keep the alcohol constant or keep the carboxylic acid constant and...
