Abstract

310,055. Schering-Kahlbaum Akt.- Ges. April 21, 1928, [Convention date]. Ketones; alcohols. - Cyclic ketones are prepared by reacting with two molecular proportions of a cyclic alcohol on one molecular proportion of a phenol in the presence of a hydrogenation catalyst at about 200<0> C. In examples, (1) two molecular proportions of cyclohexanol are heated with one molecular proportion of phenol in the presence of a hydrogenating catalyst, cyclohexanone being obtained, (2) two molecular proportions of isoborneol are heated with one molecular proportion of phenol as above, the camphor being separated by centrifuging from cyclohexanone. The catalysts employed in the examples are nickel catalysts or mixed catalysts with nickel as a basis. The Specification as open to inspection under Sect. 91 (3) (a) describes the preparation of hydrogenated and dehydrogenated compounds by causing the interaction of a more or less completely hydrogenated compound with a compound capable of taking up hydrogen in the presence of a hydrogenation catalyst, and an example is given in which isoborneol is heated with carbon monoxide under pressure in the presence of a catalyst, giving methyl alcohol and camphor. This subject-matter does not appear in the Specification as accepted.
