So42- /ZrO2 Solid Super-Strong Acid Esterification Catalyst Prepared by Supersonic Wave Technique

Abstract:

Article Preview

SO42-/ZrO2 solid super-strong acid catalyst was prepared by supersonic immersion method and the catalysts were characterized respectively by IR, BET, XRD, Element Analysis and SEM methods. The results showed that the catalyst prepared by supersonic immersion method had the larger specific surface area, the smaller grain size, the looser crystal structure, the higher surface roughness and the more border location and edge locations, which were helpful to increase the number of catalyst activity centers and was used for the esterification of polyethylene glycol oleic acid produced by oleic acid and polyethylene glycol. It also had the higher catalytic activity and longer service life.
