| abstract | Isophorone and homoisophorones are made by a process which comprises subjecting a saturated ketone of 3-5 carbon atoms and an aqueous alkali metal hydroxide solution, of such a concentration that the ketone is at least partially soluble therein, but which does not exceed 15 per cent by weight with respect to the hydroxide, to a temperature within the range between 150 DEG C. and the critical temperature of the ketone, whilst maintaining sufficient pressure in the reaction zone to maintain the contents in said zone substantially in the liquid phase. The mixture of ketone and aqueous alkali hydroxide solution may be one- or two-phase according to proportions and concentration. For a continuous process, a single-phase mixture is preferred. Examples describe the reaction of acetone and sodium hydroxide solution. Specification 583,863 is referred to. |
