γ - Undecalactone was synthesized from n-octanol and methyl acrylate using di-dert-butyl peroxide as catalyst .

以过氧化二特丁基为催化剂，通过丙烯酸甲酯和正辛醇反应合成γ 十一 内酯。

The improvement on synthetic technology of γ - undecalactone was studied . The catalyst of a mixed acid made up of perchloric acid and concentrated sulphuric acid had been adopted and the result showed that the reaction time was shortened greatly .

采用以高氯酸和浓硫酸组成的混合酸作催化剂，改进了由 ω － 十一 烯酸合成γ － 十一 内酯的反应条件，使反应时间大大缩短。
