実験手順

A mixture of 1 g. of trans/cis methyl 3,7,11-trimethyldodeca-2,4,10-trienoate, 60 ml. of methanol, 0.5 g. of potassium hydroxide and 6 ml. of water is heated at reflux for about 8 hours. The mixture is then diluted with water, neutralized and extracted with ether. The organic phase is washed with water, dried over sodium sulfate and evaporated to yield trans/cis 3,7,11-trimethyldodeca-2,4,10-trienoic acid.
