Abstract
Phenols of formula <FORM:0787135/IV (b)/1> wherein X and Y are tertiary alkyl groups and R is an alkyl or substituted alkyl (e.g. benzyl) group are prepared by reacting a 3 : 5-di-tertiary-alkyl-4-hydroxy-benzaldehyde with hydrogen peroxide in the presence of an aqueous alkali metal hydroxide solution, but in the absence of air, to give the alkali metal derivative of a 2 : 6-di - tertiary - alkyl - hydroquinone and subsequently alkylating this alkali metal derivative or the corresponding free hydroquinone. Specified alkylating agents are alkyl halides and dialkyl sulphates. In the example, equimolar amounts of hydrogen peroxide and 3 : 5-di-tertiary - butyl - 4 - hydroxy - benzaldehyde were reacted in aqueous sodium hydroxide solution, in an atmosphere of nitrogen, to give 2 : 6-di-tertiary-butyl-hydroquinone on acidification with hydrochloric acid and the hydroquinone was reacted with dimethyl sulphate to give 2 : 6-di-tertiary-butyl-4-methoxy-phenol.
