A STUDY OF HYDROGEN-BONDED SPECIES OF ACETIC ACID IN WATER
SALAG DHABANANDANA AND VITHAYA W. RUANGPORNVISUTIABSTRACT: Hydrogen-bonded species in aqueous solutions of acetic acid have been quantitatively studied in the concentration range of 0 to 85 % w/w Their presence has been indirectly determined from equilibrium. constants by a non-linear least squares treatment of proton chemical shifts. The results suggest that monomers and dimers predominantly exist within the range of 1.6 X 10-3 to 8.0 X 10-3 % w/w and 6.0 to 20.0 % w/w respectively, whereas cyclic dimers and linear dimers coexist within the range of 10.0 to 25.0 % w/w and oligomeric species are formed above 50.0 % w/w.
