Processes for converting a hydrocarbon reactant into an alcohol compound and/or a carbonyl compound are disclosed in which the hydrocarbon reactant and either a supported chromium (VI) catalyst or a supported chromium (II) catalyst are contacted, optionally with UV-visible light irradiation, followed by exposure to an oxidizing atmosphere and then hydrolysis to form a reaction product containing the alcohol compound and/or the carbonyl compound. The presence of oxygen significant increases the amount of alcohol/carbonyl product formed, as well as the formation of oxygenated dimers and trimers of certain hydrocarbon reactants.

The present invention discloses a terpinenol compound as well as its preparation method and application. The structure of such terpinenol compound is as shown in Formula (I) or (II). In Formula (I), R is independently selected from C.sub.12-C.sub.16 alkyl, NR.sup.1R.sup.2, SR.sup.3 or OR.sup.4; R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are independently selected from C.sub.1-C.sub.6 alkyl or NO.sub.2; the C.sub.1-C.sub.6 alkyl can be substituted by OH; Alternatively, the R.sup.1 and R.sup.2 form a five-member ring or six-member ring in together with N used to link up them; the five-member or six-member ring may contain one O or CO. As indicated by results of activity test, such terpinenol compound has satisfactory effect in prevention of asthma, inflammation and pulmonary artery hypertension, which also has high pharmaceutical significance.
