Process: the internationally leading ozone oxidation process of maleic anhydride is adopted. After the reaction of ozone as oxidant, there is no secondary pollution, solid products can be directly obtained, and there is no discharge of three wastes.
Quality: high purity, low impurity content, better product quality, less impact on subsequent production. It can greatly improve the yield of downstream reaction, reduce the occurrence of side reactions and improve the quality of downstream products. It is widely used in perfume, cosmetics, medicine and other high-end fields.
