Versuchsvorschrift

44.7 g of ethyl 3,5-dimethyl-cyclohexylacetate are treated with 300 ml of methanol and 15 g of potassium hydroxide, dissolved in 140 ml of water, and saponified by heating to reflux temperature for 3 hours. The working-up yields 35.6 g of a solid crude product which is used directly. A sample is distilled for the purpose of analysis.
