Synthesis of Butylparaben by Microwave

GAO Zhong-feng,HOU Guang-qiang,CUI Wei,ZHANG Xin-zhi,SUN Xue-jun(College of Chemistry and Chemical Engineering;Key Laboratory of Bioorganic Analysis,Qufu Normal University,273165,Qufu,Shandong,PRC)  
Butylparaben was synthesized with sodium hydrogen sulfate as catalyst by microwave catalysis echnology in this paper.And the influences of the amount of catalyst,acid ratio,microwave radiation time and microwave power on the product catalyst yield were discussed.The results showed the optimal reaction conditions.The molar ratio of p-hydroxybenzoic acid:butanol:sodium bisulfate was 1:2:0.036,the microwave power was 700 W,the radiation refluxing time was 25 min,After post-processing,the white crystals of butylparaben was obtained and analyzed.The yield was up to 89.70%.
