Studies On Extraction Of Octacosanol By Using Supercritical Carbon Dioxide

A study on the extraction of octacosanol in bagasse was carried out. On the basis of correlative technics, constrasting with the tradition solvent method, we used the supercritical Carbon dioxide(SCCO2)techniques and mixed solvent method. The study of the paper provide a industrializational route for a deeper utilization of octacosanol. And the study provided a correlation data for mid-experiment.Combining with the principle and character of SCCO2 and recrystal, system study and experiment work were studied by distilling and retorting octacosanol. Material extraction rate is index and extraction pressure , temperature , carbon dioxide flow quantity and accumulative density ect are experiment parameter, we acquired the best technics condition of supercritical carbon dioxide extraction and studied the influence of pressure , temperature , carbon dioxide flow quantity and accumulative density in detail. In order to retort octacosanol, we used mixed solvent method and found out the best technics route. In the recrystal process, we choosed the optimum solvent and the optimum solvent ratio. GC and GG-MS analysed the octacosanol content of primary and recrystal produce by qualitative and semi-quantitative analyse. GC determined the purity of material and produce .IR and melting point apparatus determined recrystal produce .And we verified the dynamic model of extraction in terms of experiments data.We also predesigned and economically computed the industrial flow chart, prompted the technological and economical questions of industrial production that we must think so we concluded that octacosanol was a kind of prospective nature resources and was waiting for developing.The study is not only provide a good fruit for octacosanol in SEF, but also provide a reference for the other senior alkyl mellow in SEF.
