FREQUENCY SHIFT MEASUREMENT AND ENTHALPYCHANGE CALCULATIONⅠ.FOR ADDUCTS OF PHENOLS WITH NITROGEN AND OXYGEN CONTAINING DONORS
Abstract:
Using FTIR the OH frequency shift △vOH for a series of tertiary butyl phenols (C6H5OH, 4-t-(CH3)3CC6H4OH, 2-t-(CH3)3CC6H4OH, 3,5-Di-t-[(CH3)C]2C6H3OH, 2,6-Di-t-[(CH3)3C]2C6H3OH] in reaction with several nitrogen and oxygen Lewis bases have been measured. The accuracy and reliability of the △vOH are pretty good. According to the relationship between △vOH and the helat of adduct formation △H, the latter is predicted. The calculated △H values were shown to be in reasonable agreement with experimental data.
