Procedure

200 Grams of 2,6-di-(2-ethylhexyl)-cyclohexanol were hydrogenated for 13 hours at 250° C. and 20 bar of hydrogen pressure with 10 gm of a nickel catalyst containing about 22% nickel bonded on kieselguhr in a hard fat (Pricat 9904 of Unichema). After filtration of the catalyst, 171 gm of 1,3-di-(2-ethylhexyl)-cyclohexane were obtained after distillation at 0.01 mbar between 118° and 123° C.
