Hydrogen Peroxide → 3,3',5,5'-Tetrakis(1,1-dimethylethyl)(1,1'-biphenyl)-2,2'-diol

Participants

Reaction Steps

40 g (1 mole) of sodium hydroxide are dissolved in 170 ml of water which contains 1 g of sodium lauryl sulfate. With stirring, the solution is heated to 80° and then 103 g (0.5 mole) of 2,4-di-tert-butylphenol are added. Then 31 ml of a 30% solution of hydrogen peroxide are added dropwise in the course of 2 hours. After the reaction mixture has cooled, the product is isolated by filtration and washed with water and dried, affording 100.5 g (98% of theory) of 2,2'-dihydroxy-3,3',5,5'-tetra-tert-butyl-biphenyl with a melting point of 190°-195° C.
