Preparation method of free radical initiator and application of free radical initiator in oxidation reaction

The invention discloses a preparation method of a free radical initiator, the preparation method comprises the following steps: feeding a hydroxylamine raw material, inorganic base and water according to a ratio, and carrying out acid-base neutralization reaction at 0-25 DEG C to dissociate hydroxylamine; adding tetrachlorophthalic anhydride, stirring at room temperature to react for 0.5-2 hours, reacting at 60-95 DEG C for 4-12 hours, washing with water, and drying at 60-80 DEG C for 10-24 hours to obtain an N-hydroxyl tetrachlorophthalimide crude product; and recrystallizing the N-hydroxyl tetrachlorophthalimide crude product in a mixed solvent of toluene and ethanol, filtering, and drying at 60-80 DEG C to obtain the N-hydroxyl tetrachlorophthalimide free radical initiator. According to the method, the adopted raw materials are simple, the conditions are easy to control, the preparation technology is green and environmentally friendly, the preparation repeatability is good, the free radical initiator is used in the oxidation reaction, a high-purity and high-yield product can be obtained, and the product obtained after repeated use still has high separation yield and purity.

The Cu(I)- and HNO3-catalyzed oxidation of substituted toluenes to the benzoic acid based on NOx recycling

Based on the recycling of NOx, the Cu(I)- and HNO3-catalyzed oxidation of 2-chloro-4-(methylsulfonyl)toluene to 2-chloro-4-(methylsulfonyl)benzoic acid has been developed with an excellent yield of 84.2% and a purity of 99.7%. The optimized reaction conditions (160?°C, oxygen pressure 1.5?MPa, HNO3 concentration 25?wt%, HNO3: substrate 0.5:1) use 1.0?mol% CuI as catalyst. The dosage of HNO3 in the new process is only 25% of the stoichiometric amount and 12.5% of the amount of the traditional process. The NOx emission is 5% amount of the traditional process. The oxidation of several additional toluene derivatives with comparable yields demonstrates the generality to these reaction conditions.
