Versuchsvorschrift

309.5 g (1.5 Mol) of 2,6-di-tert-butylphenol and 266.5 g (1.8 mol) of 50% aqueous glyoxylic acid are dissolved in 1400 ml of glacial acetic acid. Then, 200 g (5.5 mol) of gazeous hydrogen chloride are introduced into this solution over a period of 2.5 hours under stirring and cooling in an ice bath to keep the temperature in the 10°-25° C. range. The mixture is then stirred at room temperature overnight, cooled to 10° C., the solid is isolated by filtration on a Buechner funnel and washed with 1000 ml water. The slightly yellow and still wet cake of the intermediate product weighs about 565 g.
