실험 절차

554 g of allo-ocimene (85% 4E, 6Z; 15% 4E, 6E) and 224 g of acrolein were placed in a stainless steel vessel which is equipped to withstand a high internal pressure at elevated temperatures. 1 gm of embanox, a polymerisation inhibitor, was added. The air in the vessel was displaced with nitrogen and the vessel was closed. The temperature was raised to 165°-170° C. and maintained in the range for 6 hours. The maximum pressure recorded was 150 psi. The reaction mixture was then distilled and a mixture of four isomeric aldehydes collected which represented a 70% yield of the desired product. The percentages of adducts were determined by GLC to be as follows: ##STR6##
