Synthesis, Characterization and Activity Test of Natural Zirconium Zeolite (Zr-ZA) Catalyst in The Esterification Reaction of Glycerol with Acetic Acid Anhydride

Synthesis of Zr-ZA catalyst used as for esterification reaction glycerol with acetic acid anhydrous has been done. Catalysts are characterized using an infrared spectrophotometer, X-ray diffraction, and measurement surface acidity, while products a gas chromatography-mass spectrometer. Effect time re-addition studied by conversion selectivity value triacetin were yielded. Infra-red spectrophotometer diffraction analysis the showed that synthesized was zirconium zeolite (Zr-ZA), spectrometer product.
