Strong anion exchange resins with QN+OH-, have the
\r\npotential to be developed and employed as heterogeneous catalyst for
\r\ntransesterification, as they are chemically stable to leaching of the
\r\nfunctional group. Nine different SIERs (SIER1-9) with QN+OH-were
\r\nprepared by suspension polymerization of vinylbenzyl chloridedivinylbenzene
\r\n(VBC-DVB) copolymers in the presence of n-heptane
\r\n(pore-forming agent). The amine group was successfully grafted into
\r\nthe polymeric resin beads through functionalization with
\r\ntrimethylamine. These SIERs are then used as a catalyst for the
\r\ntransesterification of triacetin with methanol. A set of differential
\r\nequations that represents the Langmuir-Hinshelwood-Hougen-
\r\nWatson (LHHW) and Eley-Rideal (ER) models for the
\r\ntransesterification reaction were developed. These kinetic models of
\r\nLHHW and ER were fitted to the experimental data. Overall, the
\r\nsynthesized ion exchange resin-catalyzed reaction were welldescribed
\r\nby the Eley-Rideal model compared to LHHW models,
\r\nwith sum of square error (SSE) of 0.742 and 0.996, respectively.<\/p>\r\n","references":"[1]\tY. Liu, E. Lotero, J. G. Goodwin Jr., & C.
