Abstract
  • Excess molar enthalpies, HmE, of binary mixts. of anisole+glycols and polyglycols were measured by a flow microcalorimeter at 308.15 K and at atm. pressure over the whole compn. range. Binary mixts. contained anisole+diethylene glycol, anisole+triethylene glycol, anisole+tetraethylene glycol, anisole+poly(ethylene glycol)-200, anisole+poly(ethylene glycol)-300, anisole+poly(ethylene glycol)-400, anisole+poly(ethylene glycol)-600. Effects of the mol. wt. distribution (MWD), of the polymer were investigated too, by prepg. three addnl. samples of poly(ethylene glycol) (PEG) with the same no. av. mol. wt. (Mn»300), but different MWD. Values of HmE of the corresponding binary mixts. with anisole were measured. For all mixts., results were fitted to the Redlich-Kister polynomial. HmE curves are asym., showing pos. deviations for mixts. contg. glycols and poly(ethylene glycol)-200, neg. deviations for poly(ethylene glycol)-600, and an inversion of sign in the other cases. Values of HmE vary from a max. of 440 J mol-1 (anisole+triethylene (literal)
