Abstract:	超臨界流體因具有低黏滯性、低表面張性、高擴散性、高參透性、易改變的萃取選擇性及無毒性(若選用二氧化碳為操作流體)，且應用於脆取分離程序時較其他分離方法省能源，同時常壓下極易去除，沒有溶劑殘留問題。據此，超臨界二氧化碳萃取已逐漸受到重視，成為應用於特用化學品、食品工業、醫藥工業、石油工業等的新分離技術。本研究使用超臨界二氧化碳萃取紫蘇子中的紫蘇子油。為了得到最佳的萃取操作條件，文中探討了在操作壓力範圍200bar~350bar、溫度範圍313.15K~333.12K等變數對紫蘇子油萃取效率的影響。 Since supercritical fluid id low viscosity, low surface tension, high diffusibility, ease of solvent regeneration, energy saving, sensitivity to all process variables and non-toxicity (for carbon dioxide), it has received much attention as one of the new separation technologies in the specialty-chemicals, food processing, pharmaceutical and petroleum industries. The supercritical carbon dioxide is utilized to extract perilla seed oil. In order to find the best operation conditions, the extraction efficiency of perilla seed oil was investigated at pressure from 200bar to 350bar, and temperature from 313.15K to 313.15K.
