  1. DPPC is one of the important raw materials for the production of photoinitiator TPO. Its synthesis is obtained by the Friedel-Crafts reaction of benzene and phosphorus trichloride under the catalysis of aluminum trichloride.
  2. Aluminum trichloride will form a complex with the product, so it is necessary to add the decomplexing agent sodium chloride to free the product CChemicalbookDPP, which will produce a large amount of sodium tetrachloroaluminate solid waste. This part of the solid slag contains very little The odor of CDPP caused by CDPP is relatively large, and about 3 tons of solid slag is produced for every 1 ton of CDPP produced.
  3. Therefore, how to deal with the solid waste reasonably is an urgent problem for CDPP manufacturers.
