APPLICATION
1. Medicine: Used to prepare enzyme-lowering drugs for the treatment of hepatitis; drugs for the treatment of acute and chronic dermatomycosis; microemulsion composition for oral administration of biphthalate; substances containing biphenylcyclo-octene structure in the treatment of Alzheimer's disease drugs; a transparent and invisible topical pharmaceutical preparation containing biphenylbenzazole; a biphenylcyclo-octadiene lignin is used to treat antitumor drugs.
2. Pesticides: Used for the preparation of permethrin, high-efficiency, low-toxicity and low-residue green pesticides; used for the preparation of 4-biphenylsubstituted 4-substituted pyrazolidine-3,5-dione insecticides, fungicides or herbicides, biphenyls derivatives or salts thereof, and pesticides containing them as active ingredients.
3. Brightener: It can be used in the production of biphenyldichlorobenzyl, which is the raw material for the production of brightener OB-1, etc.
4. Engineering materials: used for the preparation of biphenyldianhydride to produce high-temperature and high-strength materials required for aerospace; used for the preparation of biphenylimide ultra-high temperature engineering plastics special materials; used for the preparation of carbon fiber reinforced heterophenylbiphenylpolyetherketone or heterophenylbiphenylpolyethersulfone composite materials.
5. Functional materials: additives used in the electrolyte of new energy electric vehicle batteries to effectively improve the power storage capacity, increase battery power storage, and promote the process of popularization of new energy electric vehicles.Used for the preparation of biphenyls derivatives and organic electroluminescent devices using them; used for the preparation of liquid crystal media containing monofluorotriphenyls.
6. Resin products: Used in the preparation of biphenylated diglycidyl wake-up epoxy resin; 5, 5,-tetramethylbiphenol diglycidyl ether resin.
7. Heat carrier: The preparation of biphenylbiphenylether thermal oil can be used as a heat carrier required by various chemical industries such as photothermal.
