The See also:tertiary See also:glycols are known as pinacones and are formed on the reduction of See also:ketones with See also:sodium See also:amalgam. The glycols are somewhat thick liquids, of high boiling point, the pinacones only being crystalline solids; they are readily soluble in See also:water and See also:alcohol, but are insoluble in See also:ether. By the See also:action of dehydrating agents they are converted into See also:aldehydes or ketones. In their See also:general behaviour towards oxidizing agents the See also:primary glycols behave very similarly to . the See also:ordinary primary See also:alcohols (q.v.), but the secondary and tertiary glycols break down, yielding compounds with a smaller See also:carbon content.
