响应面优化红花籽油碱异构化法制备共轭亚油酸的研究
以新疆优质红花籽油为原料,通过碱异构化法制备共轭亚油酸(CLA)。采用单因素试验研究了异构化过程中反应温度、反应时间、PEG-400用量、Fe(OH)3用量对CLA转化率的影响,同时采用响应面法对制备工艺进行优化。结果表明:在红花籽油质量为20g前提下,红花籽油碱异构化法制备共轭亚油酸的最佳工艺条件为以PEG-400为溶剂、Fe(OH)3为催化剂、反应温度178℃、反应时间2.7h、PEG-400用量265mL、Fe(OH)3用量6g,在此条件下,CLA转化率为96.54%。...

Bibliography: | safflower seed oil; conjugated linoleic acid; alkali isomerization method; response surface methodology With Xinjiang high quality safflower seed oil as raw material, conjugated linoleic acid (CLA) was prepared by alkali isomerization method. The effects of reaction temperature, reaction time, dosage of PEG -400 and dosage of Fe(OH) 3 on the conversion rate of CLA were studied by single factor experi- ment, at the same time the response surface methodology was used to optimize the preparation process. The results showed that when the mass of safflower seed oil was 20 g, the optimal preparation conditions of CLA from safflower seed oil by alkali isomerization were obtained as follows: using PEG -400 as solvent and Fe(OH) 3as catalyst, reaction temperature 178 ℃, reaction time 2.7 h, dosage of PEG - 400 265 mL and dosage of Fe(OH)3 6 g. Under these conditions, the conversion rate of CLA was 96.54 61-1099/TS ZHANG Hongyu1, WANG Shuping2, JIN Tianyou1 , XU Ruonan1 , ZHANG Xin1 GU Panpan1, WANG Fangmei1, WANG Liang1, |
