4,4''-Ditolyl Sulfone is used in preparation method of OLED material for improving luminous efficiency.
Общее описание
Di-p-tolyl sulfone is a di-p-substituted diaryl sulfone. Its synthesis by the sulfonylation of toluene with p-toluenesulfonic acid (TsOH) in the presence of polystyrene supported aluminium triflate (Ps-Al(OTf)3) catalyst has been reported along with its NMR and IR spectra. The gas-phase heats of formation of di-p-tolyl sulfone has been studied. The kinetics and thermodynamics of sulphuric acid assisted cleavage of di-p-tolyl sulfone has been invesitigated.
Методы очистки
Crystallise the sulfone repeatedly from Et2O or EtOH. It has been purified by zone melting. [Beilstein 6 H 419, 6 II 395, 6 III 1405, 6 IV 2174.]
