Although heterogeneous catalyst-based methods are known toyield FOL from dilute solutions of FAL, they mainly operate at high temperatures and/or high pressures ofhydrogen and in the presence of organic solvents. In this work, we employ bimetallic PtCo/C catalysts withvarying metal concentrations to achieve the maximum possible FOL yield (100%) at 35 °C under 0.1 MPa H2in water. With concentrated FAL (40 wt%) at 50 °C and under 1 MPa H2pressure, 86% yield of FOL wasobserved. Moreover, eﬃcient catalyst recycling was observed over at least four runs with marginal loss inactivity due to handling error and isolation of FOL in pure form conﬁrmed by NMR and HPLC.Characterization of catalysts with several physico-chemical techniques (XRD, TEM, XPS, ICP, TPR) revealsthe presence of electron-rich Pt and ionic Co species in proximity with each other and these worksynergistically to facilitate maximum possible yield of FOL under ambient conditions and in water medium</p>1 aDohade, Manisha1 aDhepe, Paresh, Laxmikant  uhttps://library.ncl.res.in/content/efficient-hydrogenation-concentrated-aqueous-furfural-solutions-furfuryl-alcohol-under01364nas a2200157   4500008004100000022001500041245014900056210006900205260000800274300001400282490000600296520074000302100002001042700002201062856012201084       2018                        eng d  a 2044-475300a Efficient method for cyclopentanone synthesis from furfural: understanding the role of solvents and solubility in a bimetallic catalytic system0 aEfficient method for cyclopentanone synthesis from furfural unde  cOCT  a5259-52690 v83 aThe platform chemical, furfural (FAL), is obtained from C5 stream of biomass, and effective conversion into various chemicals including cyclopentanone (CPO) would find many industrial applications. It is desirable to convert FAL to CPO under low H-2 pressure with high selectivity. In the current work, bimetallic catalysts with Pt as the base metal supported on carbon are evaluated in the synthesis of CPO using a biphasic solvent system. By tuning the solvent ratio, with toluene/water (3:4 v/v), 75% yield of CPO is achieved under 1 MPa H-2 at 180 degrees C. The difference in solubility of the substrate, intermediates and products, along with the optimum ratio of Pt and Co metals plays a crucial role in achieving better yields.1 aDohade, Manisha1 aDhepe, Paresh, L.  uhttps://library.ncl.res.in/content/efficient-method-cyclopentanone-synthesis-furfural-understanding-role-solvents-and
