摘要：
The association between alcohols and N,N-dimethylacetamide in carbon tetrachloride was investigated using FTIR spectroscopy at 298 K. The formation constants for 1:1 and 1:2 complexes were calculated using the method of Whetsel and Kagarise. The observed 1:1 complex values were also verified using the method of Nash. ne rate of change in C=O bond moment on complexing with alcohols increased with increasing acidity of alcohols. ne formation constant and values of free energy change increased with the increase in carbon chain length of alcohols, which suggested that the degree of complex formation varied with the length of the carbon chain of alcohols.
