Abstract: The equilibium constants of acid-base interaction between Mi(Octyl_dtp)_2 and alkylamine were determined by GLC method at several temperatures. Thermodynamic parameters △H and △S were evaluted as follows:
ethylamine: △H=-11.5kJ mol~(-1) △S=-22.7J K~(-1) mol~(-1)
diethylamine: △H=-18.1kJ mol~(-1) △S=-42.1J K~(-1) mol~(-1)
The variations of logK versus temperature fit following equations:
ethylamine: lgK=-1.19+598.9/T
diethylamine: lgK=-2.20+945.6/T
