Title:
AEROBIC OXIDATION SYSTEM CONTAINING SULFINIC ACID, SULFONIC ACID OR DERIVATIVES THEREOF AND PHOTOCATALYTIC OXIDATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/155595
Kind Code:
A1
Abstract:
Disclosed are an aerobic oxidation system and a photocatalytic aerobic oxidation method therefor. The aerobic oxidation system comprises: 1) at least one of the following substances 1a) -1d): 1a) sulfinic acid or a derivative thereof; 1b) sulfonic acid or a derivative thereof; 1c) a compound or mixture that can produce sulfinic acid or a derivative thereof by means of a reaction; 1d) a compound or mixture that can produce sulfonic acid or a derivative thereof by means of a reaction; and 2) a component containing molecular oxygen, including oxygen, an oxygen-containing gas and at least one raw material for a reaction system that can generate oxygen molecules in situ. When the aerobic oxidation system is used for an oxidation method, a series of compounds can be aerobically oxidized at room temperature to obtain corresponding oxidation products without adding a photosensitizing reagent under illuminated conditions, thereby reducing production costs; in addition, the method can greatly reduce the energy consumption, and completely solves the problem of environmental pollution caused by waste discharge of heavy metals and acidic solvents, and the problem of metal residues in products.
