반응 단계
A mixture of 25 parts of 4-methyl-2,2-diacetoxy-3-pentene, 10 parts of 3-methyl-2-buten-1-ol (prenol) and 0.3 part of propionic acid is heated for 3 hours at about 200°C in a vibratory autoclave at a pressure 30 atmospheres. After cooling, the reaction product is distilled off to give 9.4 parts of 4,8-dimethyl-3,7-nonadien-2-one having a boiling point of 60°-62°C/0.2 mm. The yield is 81% of theory at a conversion of 60% based on the prenol introduced.
