1nteractions of Threonine in aqueous Dilnethylformanlide solutions at different temperatures.

Abstract

Densities p and viscosities q of Threonine (Thr) in 5,10 and l5%(w/w) Dirnethyliormamide (DMF) - water lrixtures have been measured ati9t.iS , 303.1-5 ancl 308.15K . Fronr these expcrituental data, apparent nrolalvolurne /, , limiting partial nrolal voluure /," , the slope .S, , transfbr volltme0," , Jones-Dole coefficients B ald D were calcglated. The results shgu's astrclng solute- solvent and weak solute- solttte interactions and also intiicatethat Thr acts as structure- breaker in aqueotts DMF solvent'
