DSBP (4,4-Distyryl Biphenyl Derivative) Production from biphenyl
The manufacturing process of DSBP (4,4-Distyryl Biphenyl Derivative) starts with the reaction of biphenyl with hydrogen chloride and formaldehyde to produce 4,4’-bis(chloromethyl)biphenyl as an intermediate.

This report provides an extensive cost evaluation of DSBP (4,4-Distyryl Biphenyl Derivative) production from biphenyl. The manufacturing process of DSBP (4,4-Distyryl Biphenyl Derivative) starts with the reaction of biphenyl with hydrogen chloride and formaldehyde to produce 4,4’-bis(chloromethyl)biphenyl as an intermediate. In the next step, the intermediate is reacted with trimethylphosphite to give 4,4’-bis(dimethoxyphosphonomethyl)biphenyl. Finally, the biphenylphosphonate is reacted with two molecules of benzaldehyde-2-sulphonic acid to produce DSBP as the final product.
