実験手順

A solution of 232 g. of 7-(cyclohexan-1-on-2-yl)heptanoic acid in 2500 ml. of ethanol is refluxed for 4.5 hours with 3.8 g. of p-toluenesulfonic acid monohydrate. The solution is diluted with 200 ml. of benzene, and boiling is continued for 2 hours as 200 ml. of distillate is removed. The volume of the solution is concentrated to 500 ml. After dilution with 500 ml. of ether the solution is extracted with a solution prepared from 50 ml. of saturated sodium bicarbonate, 50 ml. of saturated sodium chloride, and 100 ml. of water. The extract is washed with saturated sodium chloride, dried, and evaporated. The product is purified by distillation to give a liquid, IR 1740 cm-1 (ester carbonyl) and 1715 cm-1 (ketone carbonyl).
