Method for synthesizing 4, 4 '-dichlorodiphenyl sulfone by using sulfoxide oxidation method

H Kasano, T Koshiba, H Kasatani

, Journal of the Physical Society of Japan

The structural phase transition in a 4,4′-dichlorodiphenyl sulfone single crystal was investigated by means of X-ray diffraction. It has been found that the crystal shows the normal-incommensurate phase transition at 150 K with the modulation wavevector q=a*±(1⁄5+δ)b*, where a* and b* represent the reciprocal lattice vectors in the normal phase and δ represents the small misfit parameter in the incommensurate phase. No lock-in phase transition was confirmed within the temperature range 20–150 K.

Characterization of 4,4'-dichlorodiphenyl sulfone impurities by gas chromatography and mass spectrometry

, Anal. Chem. 1974, 46, 7, 815–820

4,4'-dichlorodiphenyl sulfone, one of the starting materials in the production of polysulfone, was characterized and analyzed by gas chromatography and mass spectrometry. A gas chromatography method capable of separating six dichlorodiphenyl sulfone isomers was established, and the separation was achieved using a cyanosilicone oil (0V-225) column. The contents of the main impurities 3,4' and 2,4' isomers in monomer-grade 4,4'-dichlorodiphenyl sulfone were detected at 0.02% and 0.03%, respectively.
