摘  要：
桐油是一种重要用途的干性油脂,不同工艺会对油品质量产生重要影响。为了克服传统工艺在制油中的缺陷,本研究采用丁烷-亚临界法工艺进行桐油的制备,并基于Design-Expert软件进行响应面优化实验,获得最佳工艺参数:萃取温度40.64℃,萃取时间45.38 min,原料颗粒度39.71目,在此条件下桐油得油率达到66.12%。采用气质联用仪分析了桐油脂肪酸组成为α-桐酸74.93%,亚油酸8.62%,油酸7.12%,棕榈酸2.72%,硬脂酸3.85%,通过分析所得油样的5项指标,可知该工艺所得油品满足国标要求。

摘  要：
Tung oil is a kind of dry oil with important application,with different processes will have an important impact on the quality of oil products. In order to overcome the defects of traditional technology in tung oil production,the preparation of tung oil was carried out by butane subcritical process in this study,and the response surface methodology was used to optimize the experiment based on Design-Expert software. The optimum technological parameters were obtained:the extraction temperature was 40. 64℃,the extraction time was 45. 38 min,the particle size of raw material was 39. 71 mesh,and the oil yield rate was 66. 12% under this condition. The fatty acid composition of tung oil was analyzed by GC-MS showed that:the α-eleostearic acid was 74. 93%,the linoleic acid was 8. 62%,the oleinic acid was 7. 12%,the palmitic acid was 2. 72% and the octadecanoic acid was 3. 85%. Through the analysis of the five indicators of the oil samples,it is concluded that the oil obtained from the process meets the national standard requirements.
