실험 절차

A mixture of 22.8 g. of methyl angelate, 10.0 g. of 3-methyl-4-pentenol, 100 ml. of toluene and 0.9 g. of dioctyltin laurate was reacted under the same conditions as in Example 1. The resulting mixture was subjected to single distillation to give 16.91 g. of a distillate boiling at 109° C. (21 mmHg). The distillate was further subjected to rectification to give 12.54 g. of a distillate boiling at 109° C. (21 mmHg). Analysis of the compound by gaschromatography done under the same conditions as in Example 12 indicated a purity of 99.653% in terms of the area ratio. Refractive index was 1.443.
