| 中文摘要: |
| 采用工业油酸甲酯为原料，以塔顶操作压力和回流比为主要考察因素，探讨高真空间歇精馏工艺条件对C18脂肪酸甲酯分离提纯的影响。最后用Aspen软件模拟高真空间歇精馏过程。结果表明：一次精馏可以富集得到油酸甲酯与亚油酸甲酯总含量超过98%的产品，其中油酸甲酯最高含量为89.1%；在一次精馏的基础上进行二次精馏，塔顶可获得含量高达94.7%的油酸甲酯产品；Aspen软件模拟结果与实验数据吻合良好。 |
| 英文摘要: |
| With industrial methyl oleate as raw material, reflux ratio and operation pressure in the top of tower as the main factors, the effect of high vacuum batch distillation process conditions on the separation and purification of C18 fatty acid esters were studied，then Aspen was used to simulate the high vacuum batch distillation. The results showed that in the first distillation, total content of methyl oleate and methyl linoleate in the product was above 98%, in which the content of methyl oleate was 89.1%. Based on the first distillation, the second distillation was carried out and the content of methyl oleate increased to 94.7% in the top of tower. The simulation results of Aspen agreed well with the experimental results. |
