Abstract
Vapour-liquid equilibrium data for trimethyl borate-methanol-dimethyl sulfoxide and trimethyl borate-methanol-N-methyl-2-pyrrolidinone were measured at 101.3 kPa. The data were fitted to the frequently used models: non-random two-liquid, universal quasichemical and Wilson. Results proved that the vapour-liquid equilibrium data agreed well with the non-random two-liquid model. Addition of both solvents produced notable effect on the relative volatility of trimethyl borate to methanol. An interesting phenomenon is that the optimum solvent performance occurs at totally different concentration of trimethyl borate. This indicates an enhancing solvent effect could be brought about by combination of the two solvents.
