Abstract
The pinacol which results from the reduction of 4-hydroxy-propiophenone by any method which may be used to produce pinacols from ketones is isolated from the reaction mixture by a process which comprises acylation with an aromatic acylating agent followed by separating the acylated product and hydrolysing. The pinacol which is thus formed is g : d -bis - (4 - hydroxyphenylhexane) - g : d - diol. Suitabl acylating agents are benzoyl chloride and toluene-p-sulphonchloride. In examples: (1) 4-hydroxypropiophenone is reduced by sodium amalgam in aqueous alkaline solution and the product acylated with benzoyl chloride. The dibenzoate is separated, purified and hydrolysed; (2) as in example (1), but using as the aromatic acylating agent, toluene-p-sulphonchloride. Specifications 523,515 and 566,723 are referred to.
