| titleOfInvention | Preparation method of 2-chloropyridine n-oxides |
| abstract | The invention discloses a preparation method of 2-chloropyridine n-oxides. According to the preparation method, 2-chloropyridine and catalytic agents are mixed according to a mass ratio of 1 : (0.05-0.5), the 2-chloropyridine and the catalytic agents are stirred at the temperature between 40 DEG C and 90 DEG C, and hydrogen peroxide is added for reaction; the temperature is kept unchanged, the mixture is stirred for performing reaction for 3-10 hours, then the temperature is lowered to a normal temperature, and after the reaction, the mixture is filtered to obtain a 2-chloropyridine n-oxide water solution; the molar ratio between the hydrogen peroxide and the 2-chloropyridine is (0.8-3.5) : 1; and the catalytic agents use mesoporous molecular sieves (MCM-41) as carriers. Under the actions of the high-activity and high-selectivity catalytic agents, the 2-chloropyridine is reacted with the hydrogen peroxide to obtain the 2-chloropyridine n-oxides, the reaction conversion ratio of the 2-chloropyridine reaches 100%, and the yield of the 2-chloropyridine n-oxides reaches above 98%. |
