Abstract: The present invention provides a method to effectively inhibit the oxidization of VO(acac)2 in solution for months. It is believed that VO(acac)2 forms a ?-complex with as many as three allylic alcohols which precludes reaction with any oxygen in the system. Although saturated and homo-allylic alcohols were also tested, this effect appears only in the allylic-alcohol based solutions. This ability to inhibit oxidation of VO(acac)2 allows these solutions to be used for making thermochromic VO2 film much more easily and economically as it avoids the requirement of operating under low oxygen level conditions. Thus the present invention provides a method of stabilizing vanadium oxyacetylacetonate (VO(acac)2) in solution against oxidation for extended periods of time, comprising the steps of mixing the oxyacetylacetonate precursor in an allylic alcohol prior to spin-coating for VO2 film formation. The allylic alcohol may be ?-methallyl alcohol.

Abstract: A process for making trans-isocarveol, an intermediate useful in the manufacture of perillyl alcohol, is disclosed. The process comprises isomerizing a mixture comprising cis-limonene oxide (cis-LMO) and trans-limonene oxide (trans-LMO) in the presence of a phenolic modifier and a chromium catalyst. The process is performed at a temperature less than 220° C. to convert more than 50% of the cis-LMO to trans-isocarveol and less than 50% of the trans-LMO to cis-isocarveol.

Abstract: A process for making perillyl alcohol is disclosed. The process comprises isomerizing a starting material comprising trans-isocarveol at a temperature within the range of 100° C. to 220° C. in the presence of a Group 5 metal catalyst to produce perillyl alcohol. We surprisingly found that trans-isocarveol, which can be selectively produced from a commercially available mixture of cis- and trans-LMO, can be isomerized directly to perillyl alcohol. Yields of perillyl alcohol are improved when the isomerization is performed under an inert atmosphere and/or in the presence of a phenolic antioxidant. Performing the isomerization in the presence of a high-boiling alcohol and/or distilling the perillyl alcohol product from the reaction mixture in the presence of a high-boiling alcohol, enhances yields and maximizes catalyst use. The resulting distillation residue, which contains recovered Group 5 metal catalyst, is valuable for catalyzing additional trans-isocarveol isomerizations.
