Interactions of Threonine in aqueous Dimethylformamide solutions at different temperatures

Densities p and viscosities Tl of Threonine (Thr) in 5, I 0 and 15% (w/w) Dimethylformamide (DMF) - water mi xtures haYe been measured at 7.98. 1) , 303. 15 and 308.1 SK . From these experi mental data, apparent rn olal volume ¢ .. , limiting parti al mol al vol ume ¢.° , the slope S, , transfer volume ¢.°, , Jones-Dole coefficients B and D were ca lcu lated. The res ults shows a strong solute- solvent and weak solu te- so lute interactions and also indicate that Thr acts as structu re-breaker in aqi.1eous D1VIF sol ve nt
