摘要: The enthalpies of the mixture of (S)-2-amino-5-guanidinopentanoic acid and (2S)-pyrrolidine-2-carboxylic acid with 1,3-butanediol, 2,3-butanediol, and their respective enthalpies of dilution in aqueous solutions at 310.15 K were determined as a function of the mole fraction by flow microcalorimetric measurements. These experimental results have been analyzed to obtain the heterotactic enthalpic interaction coefficients (h) according to the McMillan?Mayer theory. It has been found that the h coef...更多; The enthalpies of the mixture of (S)-2-amino-5-guanidinopentanoic acid and (2S)-pyrrolidine-2-carboxylic acid with 1,3-butanediol, 2,3-butanediol, and their respective enthalpies of dilution in aqueous solutions at 310.15 K were determined as a function of the mole fraction by flow microcalorimetric measurements. These experimental results have been analyzed to obtain the heterotactic enthalpic interaction coefficients (h) according to the McMillan?Mayer theory. It has been found that the h coefficients between (S)-2-amino-5-guanidinopentanoic acid and (2S)-pyrrolidine-2-carboxylic acid with butanediol molecules in aqueous solutions at 310.15 K are all positive. The results are discussed in terms of solute?solute and solute?solvent interactions.收起
