Oxidation of hydrocarbons

摘要

A process for oxidizing a first hydrocarbon to a corresponding first oxygenate by feeding a first feedstock comprising the first hydrocarbon into an oxidation reactor, contacting the reaction medium with a gas stream comprising O2 in the oxidation reactor, and supplying a hydroperoxide additive to the oxidation reactor. By including the hydroperoxide additive in the reaction medium, foaming at and/or close to the beginning of the oxidation reaction can be significantly reduced.

1. A process for oxidizing a first hydrocarbon, the process comprising:
(S-I) feeding a first feedstock comprising the first hydrocarbon into an oxidation reactor to obtain a reaction medium; (S-II) contacting the reaction medium with a gas stream comprising 02 in the oxidation reactor; (S-III) supplying a hydroperoxide additive to the oxidation reactor such that the total concentration of hydroperoxide compound(s) in the reaction medium is in a range from 3.1 wt % to 20.0 wt %, based on the total weight of the reaction medium in the oxidation reactor; (S-IV) measuring a first pressure inside the oxidation reactor at a first location in proximity to and above a projected level of the top surface of the reaction medium; (S-V) measuring a second pressure inside the oxidation reactor at a second location in proximity to and below the projected level of the top surface of the reaction medium; and (S-VI) controlling at least one reaction condition parameter inside the oxidation reactor based on the first pressure measured in step (S-IV) and the second pressure measured in step (S-V).
