in synthesizing ethyl acetate by fischer esterification a Vernier Mini GC will be used. the GC uses a metal column with a nonpolar coating and atmospheric air as the mobile phase, in addition, the temperature of the GC can be varied. under these conditions, what component will show up first in your chromatogram? ethyl, acetic acid or ethyl acetate?
1. Is in refrence to a fischer esterification reaction using an alcohol and carboxylic acid to synthesis octyl acetate. https://i.sli.mg/W4ALMZ.png Thank you in advance!
This experiment involved the use of Fischer Esterification to create isopentyl acetate from reacting isopentyl alcohol with acetic acid and sufluric acid. 1. Provide a balanced equation to explain the evolution of gas during the sodium bicarbonate washing step. 2. The microscale synthesis of esters often uses a Dean-Stark trap. A Dean-Stark trap separates and collects water during a reaction. How would using a Dean-Stark trap during a Fisher-Esterification affect the synthesis? 3. Esters are often used in artificial flavorings....
