More Information
Summary:The invention provides a method for preparing a piperidine nitrogen oxygen-derived free radical polymerization inhibitor, which has the advantages that: firstly, the reaction time is short, the reaction condition is mild, and the operation is simpler; secondly, a catalyst has cheaper price and low cost, is convenient to separate, and can be reused; thirdly, the yield is higher; and fourthly, water is taken as a solvent, and the method for direct drying by distillation cannot generate waste solution and wastewater, does not pollute the environment, and realizes zero release in industrial production in a real sense. Therefore, the method is a method for preparing piperidine nitrogen oxygen-derived free radicals, and provides convenience for industrial production.
