Why is the sulfuric acid necessary? Because the presence of water molecules or moisture tends to shift the reaction in a backward direction and decrease the yield. z@{[Qfp(Ukqxd45yIBU`!I)rW,XQRrf#M$N5S7ruK7> .T;kdViOD,xpsCF0#(x^gVEj0fZ[EDyNt'G|f }g Gd xc9XX}fh|A@S*F4ie1GP[%YyiSE+J.EbH:tHN3jJBsU7)W}J{0Is.`=fS5~ja|S?$ufYNA]eVD&t6PBIGbJh1N3$bo$c#^9)YKSc+;\vW% HWKs6WH$(N=%9e%: AL3&,i_ L0Y9R`ja8lv:u;=+p`V{=/ xb```f````c`ef`@ ;FE F7&&u'9UP_@XS`zB9jvYKx7{X0HmRz|%zXeWELa47t*rMK88o]#J2AD3HZsw5:f&2yk}e"vmuzMR^wY$ A commercially important esterification reaction is condensation polymerization, in which a reaction occurs between a dicarboxylic acid and a dihydric alcohol (diol), with the elimination of water.

Draw the mechanism of esterification using acid chloride and alcohol. 4. My stating material was 10 of benzoic acid and at the end I had 2 of methyl Why is alcohol used in excess in this reaction? When a carboxylic acid reacts with an alcohol, it produces an ester. The partially positive carbon becomes susceptible to the attack of negatively charged species such as the oxygen atom of alcohols. While separating the layers, it gauge when to close the stopcock perfectly, so that led to a loss of eventual product. 0000011809 00000 n

As steric crowding slows down the rate of reaction,primary alcohols are mostly used for this reaction. And the equation (3) is not balanced. Another reason could be loss of Predict and draw the products of the reaction methyllithium with ethanol. The reaction mixture of benzoin, prepared by the method described on p. 94, is permitted to stand until the next day, when it is filtered, washed with water but is not dried or purified.
