PURPOSE: A dibasic acid forming method and device are provided by oxidizing a hydrocarbon. CONSTITUTION: A single phase at the operating temperature is attained and maintained by adjusting one or more of gaseous oxidant flow rate, pressure in the reaction zone, temperature in the reaction zone, feed rate of hydrocarbon, feed rate of solvent, feed rate of water if water is being fed, feed rate of the catalyst and other parameters. A hydrocarbon is reacted at a steady state with a gaseous oxidant to form an acid in a liquid mixture. The amount of water is maintained between a maximum level of water, over which maximum level the substantially single liquid phase is transformed to two liquid phases, and a minimum level under which catalyst precipitates. At least part of the formed acid is then removed. The preferred hydrocarbon is cyclohexane, the preferred acid is adipic acid, and the preferred solvent is acetic acid.
