Abstract: Disclosed is a continuous industrial production method of high-purity bisphenol A-bis(diphenyl phosphate). The method includes: dividing bisphenol A into two parts, mixing a part of the bisphenol A with phosphorus oxychloride and a Lewis acid catalyst, adding the mixture into a continuous multistage crosslinked reactor, removing excessive phosphorus oxychloride through distillation, adding an organic base acid binding agent and the rest of the bisphenol A to react for 1.5 to 3 h at a temperature of 115° C. to 120° C.

Abstract: The present invention discloses a preparation method of a cardanol-modified polyamine curing agent with high corrosion resistance. The method includes the following steps: subjecting cardanol, paraformaldehyde and an amine compound to Mannich reaction, after the Mannich reaction, adding a water-soluble initiator for polymerization reaction, then evaporating water and excessive amine compound under reduced pressure after the polymerization reaction, thus obtaining a cardanol-modified polyamine curing agent. The coating obtained by curing the curing agent with an epoxy resin has greatly improved chemical resistance and corrosion resistance, indicating that the use of the water-soluble initiator in this present invention enables olefins to be polymerized very well, and molecules are reinforced obviously after polymerization, thereby greatly improving the chemical resistance and corrosion resistance.
