實驗室小型精餾塔分餾松節油中蒎烯

【摘要】通過添加乙二醇為共沸劑,探索添加乙二醇減壓共沸精館分離松節油中a-蒎烯β-蒎烯,并與減壓精餾進行比較,考察前者分餾效果

【關鍵詞】減壓精餾裝置;共沸精餾裝置;乙二醇;松節油

2.1材料和設備

濕地松松節油:(α-50.53%,β-旅烯38.53%)

乙二醇:國藥試劑

旋片真空泵:2X2-4型,上海真空泵廠;

從濕地松松節油中主要成分為a-蒎烯與β-蒎烯,約占總量的87%~91,α-旅烯:β-蒸烯=2.1-1.5:1,此外還有獲烯、月桂烯、雙戊烯、β-水芹烯等其他森烯組分。彼此沸點相距很接近,通過精餾分離濃度較大。國外采用100理論塔板數的精餾塔分餾,a-萊烯和β-藻烯的純度達到98%以上。國內基本采用60~70理論塔板數的精餾塔分餾a-蒸烯和β-藻烯的純度達到95%以上和90%以上,與國外產品有比較大的差距。
