摘要
采用溶剂法提取橡胶籽油,在单因素试验的基础上,用正交试验优化橡胶籽油的提取工艺。结果表明,橡胶籽油的最佳提取工艺为:提取溶剂为石油醚(60～90℃),原料粒度0.90 mm的橡胶籽20 g,液料比7∶1(mL∶g),提取温度75℃,提取时间8 h,此时橡胶籽油的得率为35.17%。
In order to study the process optimization for extraction of rubber seed oil,the solvent extraction method was used.The petroleum ether was used as extracting solvent.According to the single factor test the effects of liquid-solid ratio,extraction time,and extraction temperature on the extraction ratio of rubber seed oil were investigated through orthogonal design.The optimum extraction conditions were as follows： petroleum ether as extracting solvent,the sample particle 0.90 mm,rubber seed 20 g,liquid-solid ratio of 7 ∶ 1（mL ∶ g）,the extraction temperature 75 ℃,and the extraction time 8 h.Under the optimum condition,the extraction ratio of rubber seed oil was 35.17 %.
