実験手順

513 g of 2-n-pentyl-3-(1-carbethoxy-2-oxopropyl)-1-cyclopentanone were mixed in an autoclave with an equal weight of water. The autoclave was then purged of the air which it contained, closed and heated up to a temperature of 140°-150° C for 2 hours. After cooling, extraction, washing and distillation, there was obtained 332 g of 2-n-pentyl-3-(2-oxopropyl)-1-cyclopentanone (yield = 90.6%) having nD20 = 1.432 and d420 = 0.961.
