VERFAHREN ZUR HERSTELLUNG VON 4,4'-DIHYDROXY-DIPHENYLSULFONEN

A phenol is reacted with sulphur trioxide in the presence of liquid hydrogen fluoride to form a 4,4'-dihydroxydiphenylsulphone. A molar excess of hydrogen fluoride and stoichiometric proportions of sulphur trioxide and phenol or a slight excess of sulphur trioxide over phenol are preferred.
