Dimethyl isophthalate synthesis

9synthesis methods
Dimethyl isophthalate is synthesized by esterifying isophthalic acid with methanol: Isophthalic acid (1.66gm, 0.1mmol) in super dry methanol (60mL) containing 2-3 drops of concentrated H2SO4 (AR) was refluxed till it dissolved. Then, the reaction mixture was poured onto ice cold water, immediately a solid started separating from the clear solution. To this a solution of sodium bicarbonate was added till the effervescence seized. The ester thus obtained was filtered and washed with water for several times (M.P: 64-67°C).
