Abstract
4,4,8,8,10-pentamethylbicyclo[4,4,0]-decene-(1,6)-one(2), is produced from the bottom product of the acetone condensation reaction collecting in the production of isophorone by fractionation. A ketone blend consisting essentially of C.sub.15 compounds where the main components are isomers [B] and [C] as shown in the general formulas: ##STR1## is isolated. This ketone blend is selectively hydrated in the presence of a noble metal catalyst at hydrogen pressures of 20 to 250 mbars and at temperatures between 25.degree. and 150.degree. C. The 4,4,8,8,10-pentamethylbicyclo[4,4,0]-decene-(1,6)-one(2) is obtained by rectifying the hydration output.
