Abstract

Bentonite-Mo(HPO4)3 has synthesized by molybdenum phosphate variations and applied as a catalyst for ethanol conversion to diethyl ether. Natural bentonite is prepared until Na-bentonite was obtained. Na-bentonite has increase CEC from 92 mEq/100 g to 122,6 mEq/100 g. Bentonite-Mo(HPO4)3 was pilarization from ammonium heptamolybdate and diammonium hydrogen phosphate with 2, 4, 6, 8 and 10 mEq/g variations and then characterized using acidity analysis, XRD, FTIR, SEM-EDS and GSA. The results of the acidity analysis showed that the acidity catalyst increased from 2.40 mmol/g for Na-bentonite to 3.84 mmol/g, 6.25 mmol/g, 8.53 mmol/g, 6.03 mmol/g and 8.28 mmol/g for each variation of 2, 4, 6, 8 and 10 mEq/g. The results of the characterization bentonite-Mo(HPO4)3 6 mEq/g using XRD showed typical peaks of molybdenum at 2θ 26.473° and 30.61°. Absorption bands at wavenumbers 966, 2341, 874 dan 1048 cm-1 which were Mo-O, OH of HPO4 dan P-O vibrations from FTIR bentonite-Mo(HPO4)3 6 mEq/g. The morphology of bentonite-Mo(HPO4)3 6 mEq/g was seen from SEM had increased pore and Mo and P elements were seen from EDS results. Characterization of bentonite-Mo(HPO4)3 6 mEq/g using GSA showed an increase in specific surface area to 102 m2/g, pore volume to 0.1606 cm3/g and pore diameter to 62.98 Å. Ethanol conversion to diethyl ether measurements using GC-MS showed that bentonite-Mo(HPO4)3 6 mEq/g has greater ethanol conversion than other variations.
