Synthesis of Terpene-dimethyl Maleate Adduct under Atmospheric and Pressurized Conditions
摘要
Abstract
Terpene-dimethyl maleate adduct was prepared under atmospheric and pressurized conditions from industrial dipentene and dimethyl maleate as a dienophile. Under atmospheric condition, the yield of terpene-dimethyl maleate adduct was 55% after reflux at 185 ℃ for 10 h. In the hermetic autoclave, the yield of terpene-dimethyl maleate adduct achieved at 78.6 % after 2 h at 240 ℃ and 1. 5 MPa. The adduct was characterized by GC-MS, 1H NMR and FT-IR. GC-MS indicated that there were 20 geometric isomers. The mass charge ratio of those molecular ion peaks was 280. 1 in the purified adduct and the purity was 95.2%. The content of the Diels-Alder adduct was about 35% of the purified adduct which was calculated from 1H NMR.关键词
