Abstract

p-phenol-sulphonic acid is prepd from phenol and 6U-90 pref 70-80% sulphuric acid at constant ratio of 1:1.0-1.1 phenol to sulphuric acid at 90-110 pref 95-100 deg.C temp, in less than 8, pref 2-5 hrs. To counteract dilution by water produced, steam is continuously removed by stream of inert gas; raised reaction temp above 100 deg.C pref 120 deg.C; or reduced pressure. - (1pp)
