Title:
SYSTEM AND PROCESS FOR ENHANCING TOLUENE OXIDATION
Document Type and Number:
WIPO Patent Application WO/2021/047052
Kind Code:
A1
Abstract:
A system and process for enhancing toluene oxidation, belonging to the technical field of preparing benzoic acid. A traditional bubble reactor is replaced with a tubular reactor (3) to improve the controllability of the oxidation reaction process; a micro-interface generator (4) is provided in the tubular reactor (3) to increase the gas-liquid phase interface area of oxygen and toluene, so as to improve the reaction efficiency; a casing pipe having a two-layer structure of an inner tube (11) and an outer tube (12) is provided to achieve the effect of using excessive heat of a reaction product for preheating the toluene, so as to reduce the loss of energy; compared with the traditional technology for preparing benzoic acid, the tubular reactor (3) is replaced and the micro-interface generator (4) and a separation unit (5) are added into the reactor (3), so as to improve the yield of the product.
