ABSTRACT:
This invention relates to methods and devices of preparing acids, such as adipic acid for example, by oxidizing a hydrocarbon, such as cyclohexane for example, with a gas containing an oxidant, preferably oxygen. A respective hydrocarbon is reacted, preferably at a steady state, with a gaseous oxidant to form an acid in a liquid mixture which preferably contains a solvent, a catalyst, water, and an initiator. The ratio of solvent to hydrocarbon may be controlled in a manner to maintain in the reaction zone maximum reaction rate and/or reactivity, or reaction rate and/or reactivity within a desired range, or reaction rate and/or reactivity directed toward a desired range. In addition, the ratio of solvent to hydrocarbon is controlled in a manner to maintain in the reaction zone substantially maximum selectivity and/or yield, or selectivity and/or yield within a desired range, or selectivity and/or yield directed toward a desired range.
