Dehydration of 1 2propanediol to propanal and propanone using HZSM5 and HMOR catalysts by ONIOM method
Abstract:
The reaction on HZSM5, HMOR and HTON catalysts are individually composed of three steps for 1,2propanediol conversion to propanal and four steps for conversion to propanone. The reaction mechanisms for dehydration of 1,2propanediol to propanal and propanone over HZSM5, HMOR and HTON cata-lysts were studied using ONIOM (B3LYP/631+ G(d):AM1) method. Thermody-namic properties, reaction energies, rate and equilibrium constants of 1,2propanediol to propanal and propanone over HZSM5, HMOR and HTON catalysts reactions were determined at 298.15 K. The rate constants for 1,2propanediol conversion to propanal and 1,2propanediol conversion to propanone over HZSM5, HMOR and HTON catalysts are in decreasing orders: HTON > HZSM5 > HMOR, and HZSM5 > HMOR > HTON, respectively.
