摘要
对利用超临界ＣＯ２ 从豆油脱臭馏出物中萃取、浓缩生育酚的工业化生产的可行性进行了试验研究，提出了初步的工艺框架，研究了压力、ＣＯ２ 流量及温度场分布对精馏柱萃取效果的影响－ 研究结果表明，为了保证α生育酚的浓缩效果，适宜的萃取压力为１３－５ ＭＰａ 、ＣＯ２流量为３ ～５ Ｌ／ｍｉｎ ，精馏柱温度分布为６０／５０／４０／３５ ℃（ 顶／ 上中／ 下中／ 底）－
An experimental study was carried out on the feasibility of industrialization of extraction and concentration of α tocopherol from soybean deodorized sludge by using supercritical carbon dioxide.A preliminary frame of this technology has been established.The effects of the pressure,temperature and CO 2 volume of flow on the extraction and concentration are studied.The experimental result shows that,to raise concentration of α tocopherol,suitable extraction pressure is 13.5MPa,CO 2 volume of flow is 3～5l/min,and temperature gradient along distillation column is 60/50/40/35℃(top/high middle/low middle/bottom).Methods for further improvement are put forward.
