Catalytic hydrogenolysis/hydrogenation of bioglycerol leads to 1,2 and 1,3-propanediols, which can befurther valorized to industrially important products through a variety of reactions such as etherification, esterification and cyclization through acetalization. In the current work, selective mono-etherification of 1,3-propanediol (PDO) with isopropanol to 3-isopropyl-1-propanaol was systematically studied, using 20% w/w Cs2.5H0.5PW12O40/K-10 catalyst in an autoclave at 170°C. In a typical reaction, using 1:6 molratio of 1,3-PDO to isopropanol at 0.03 g/cm3 catalyst loading and 1000 rpm, 60% conversion wasachieved with 100% selectivity to the product. The catalyst was prepared by incipient wetness tech-nique and characterized by various techniques such as X-ray diffraction, surface area measurement byN2 adsorption-desorption, FTIR, and SEM. Effect of various reaction parameters on conversion and selectivity was studied to establish kinetics and mechanism. The catalyst is robust and reusable. The overallprocess is green and clean.
