Abstract
2, 6-Di-t-butylphenol-4-sulphonic acid is prepared by adding 2, 6-di-t-butylphenol to concentrated sulphuric acid and pouring into ice/water. After extraction with ether, barium carbonate is added, the barium sulphate filtered off, and the filtrate evaporated. The barium salt is dissolved in water and treated with sodium sulphate to give the sodium salt. 2, 6-Diphenyl-4-chlorophenol is prepared by diazotizing 2, 6-diphenyl-4-aminophenol with sodium nitrite in hydrochloric acid and treating the diazonium salt with cuprochloride in hydrochloric acid. Specifications 880,862, 975,928, 975,930 and 975,939 are referred to.
