Research on the Supercritical Extraction of Seed Oil from Rubber Tree and Its Composition Analysis
摘要
Abstract
[Objective] The reference for the study on the bio-diesel from rubber tree was provided through the test of supercritical extraction process of seed oil and its composition of fatty acid.[Method] The effect of the extraction temperature, pressure, time and the amount of co-solvent on seed oil was studied with the orthogonal experimental design and the analysis of the composition of fatty acid was conducted.[Results] The best condition of the extraction of rubber seed oil with CO2 supercritical fluid was as follows: the extraction temperature, 45 ℃; the extraction pressure, 40 MPa; the extraction time, 2.5 hours; the amount of ethanol co-solvent, 15% and under these conditions, the extraction rate of rubber tree seed oil was 19.60% and with the color of clear oil.The calculative value of HPLC area normalization was as follows: the myristic acid, 0.13%; the palmitic acid, 9.34%; the palm oil acid, 0.30%; the stearic acid, 8.07%; the oleic acid, 25.90%; the linoleic acid, 39.79%; the linolenic acid, 15.75%; the arachidic acid, 0.34%; the peanut-acid, 0.38% and the unsaturated fatty acid, 82.12% with gas chromatography-mass spectrometry, which was conducive to the preparation of bio-diesel.[Conclusion] The supercritical CO2 fluid extraction of rubber seed oil can be used as the potential preparation of bio-diesel resource.关键词
