実験手順
A mixture of 1 g. of trans/cis methyl 3,7,11-trimethyldodeca-2,4-dienoate, 60 ml. of methanol, 0.5 g. of sodium hydroxide and 6 ml. of water is stirred at about 30° for about 56 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-dienoic acid.
