Butylparaben is derived from the esterification between p-hydroxybenzoic acid and butanol. Butanol and p-hydroxybenzoic acid are heated together for being dissolved, slowly added dropwise of sulfuric acid, continue the refluxing for 8h. After cooling, add 4% sodium carbonate solution, separate the water layer, steam out the butanol, let it cool, filter to obtain the crude product, and then carry out ethanol recrystallization (solubility in ethanol: 200g/100ml).
Take sulfuric acid as a catalyst; derive it from the reaction between p-hydroxybenzoic acid and butanol.


Butylparaben can be used for the antibacterial and anticorrosion of drugs, cosmetics and food.
