摘要：	The heats of protonation of N-(para-substituted phenyl) glycines (R—C_6H_4—NHCH_2COOH, R=CH_3O, CH_3, H, C1) and the heats of formation of these amino acids with copper(Ⅱ) have been determined calorimetrically at 25℃ in 30% (v/v) ethanol in the presence of 0.1M sodium perchlorate. The data obtained conform nicely to the equation △H_(ML)-Q-β△H_(HL) where △H_(ML) denotes the heats of formation of complex compounds, △H_(HL) denotes the heats of protonation of the ligands, and Q and β are constants.
