Acetylation of different hexanediols as a complex reaction has been in
vestigated by calorimetry. The calorimetric curves demonstrate that th
e reaction rate depends on the molecular structure. in case of 1,6- an
d 2,5-hexanediols, the activation parameters have been obtained by non
linear evaluation procedures with the program TA-kin v3.3. The kinetic
results show, that the formation of the diester is characterized by h
igher activation energies than that of the monoester. (C) 1998 Elsevie
