Heteropoly acid, H3PW12O40 is highly soluble strong acidic catalyst with well-defined structure. This study reports the modification of soluble heteropoly acid to insoluble and reusable heteropolyacid (HxZr3-xPW12O40 ) by exchanging with Zr and investigation of its catalytic performance in selective transformation of renewable fructose to 5-HMF in Dimethyl sulfoxide (DMSO) system. The physico-chemical properties of H(x)Zr(3-x)PW(12)O(40)were derived from Powder-XRD, NH3-TPAD and FT-IR technique. The characterization of HxZr3-xPW12O40 revealed that the Keggin structure of HPA remained intact as proton replaced by Zr. The partial exchange of Zr in H2Zr1PW12O40 catalyst resulted in an increase in acidity, however further increase of Zr above 1, acidity was found to be decreased. At optimized reaction condition, 5-HMF yield of 85% with 100% selectivity was achieved with H1Zr2 PW12O40 catalyst at much lower reaction time of 10 min than reported. The catalyst was observed to be recoverable, reusable as compared to parent H3PW12O40.</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue><work-type><style face="normal" font="default" size="100%">Article</style></work-type><custom3><style face="normal" font="default" size="100%">Foreign</style></custom3><custom4><style face="normal" font="default" size="100%">Not Available</style></custom4></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Mulik, Nagesh L.</style></author><author><style face="normal" font="default" size="100%">Niphadkar, Prashant S.</style></author><author><style face="normal" font="default" size="100%">Bokade, Vijay V.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Synthesis of ethyl furfuryl ether (potential biofuel) by etherification of furfuryl alcohol with ethanol over heterogenized reusable H1Cs2PW12O40 catalyst</style></title><secondary-title><style face="normal" font="default" size="100%">Research on Chemical Intermediates</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">B</style></keyword><keyword><style  face="normal" font="default" size="100%">etherification</style></keyword><keyword><style  face="normal" font="default" size="100%">Ethyl furfuryl ether</style></keyword><keyword><style  face="normal" font="default" size="100%">Furfuryl alcohol</style></keyword><keyword><style  face="normal" font="default" size="100%">H3-xCsxPW12O40</style></keyword><keyword><style  face="normal" font="default" size="100%">Heterogenized heteropoly acid</style></keyword><keyword><style  face="normal" font="default" size="100%">L ration</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2020</style></year><pub-dates><date><style  face="normal" font="default" size="100%">APR</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">46</style></volume><pages><style face="normal" font="default" size="100%">2309-2325</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;{Ethyl furfuryl ether (EFE) considered as potential biofuel can replace petroleum diesel up to 100%.
