Table 2. Kinetic Equations of the Three Resin Acids.
resin acids | a | b | kinetic equation | activation energy (kJ/mol) | correlation coefficient R2 |
---|---|---|---|---|---|
levopimaric acid | 0.001625 | 0.003800 | ln[(0.001625 – x)/(0.003800 – x)] = –459.8kt – 0.8495 | 42.90 | 0.995 |
neoabietic acid | 0.001620 | 0.003783 | ln[(0.001620 – x)/(0.003783 – x)] = –462.3kt – 0.8481 | 58.05 | 0.976 |
dehydroabietic acid | 0.001795 | 0.003433 | ln[(0.001795 – x)/(0.003433 – x)] = –610.5kt – 0.6484 | 46.60 | 0.989 |
