Abstract
The reaction of dibutyltin oxide with 5-sulfosalicylicacid gave a new dibutyltin(IV) sulfonate which can be used as the catalysts for the synthesis of methylparaben under microwave irradiation.The effect of the synthetic conditions on the esterification were investigated.The advantages of the present procedure are high yields and short reaction time,the yield of methylparaben reached 93%.
