The rate of thermal isomerization of ocimene in the liquid phase has been investigated in the range 90-150°C. The rate constant for the disappearance of ocimene may be expressed by k=1.3×1010e -11994.2/T(min-1), from which we can infer that the activation energy is 99.7kJmol-1 and the pre-exponential factor is 1.3×1010min-1. The half-life for the disappearance of ocimene may be expressed by t1/2=5.2×10-11e 11994.2/T(min). The conclusion has been supported by the study results that the ocimene is safe when temperature is below 100°C. A discussion of the mechanism concerning the conversion is included. Copyright

The photostationary state compositions and quantum yields of the benzophenone-sensitized geometric isomerization of alloocimene, a model triene, have been studied in detail.The results arte discussed in terms of two reaction schemes for four isomer systems (one for steady-state concentrations of isomers and one for partially eequilibrated isomeric triplets).A triplet torsional potential surface of the triene is also presented which was constructed to reflect the photochemical properties of the triene.From quenching data, the average lifetime of an alloocimene triplet at room temperature was determined to be 2E-7 s.
