【摘要】 摘 要 橙花醇、香叶醇、乙酸芳樟酯和乙酸香叶酯（指乙酸香叶酯和乙酸橙花酯的混合物）是β－蒎烯路线合成香料中的重要产品。本文以β－蒎烯路线生产的混合醇产品（香叶醇和橙花醇的混合物）以及生产过程中的中间产物乙酸酯类混合物（乙酸芳樟酯、乙酸香叶酯）为原料，创新性地进行了产品深度开发研究，得到了符合高标准质量及收率要求的香叶醇、橙花醇、乙酸芳樟酯和乙酸香叶酯四种产品，为工业化生产奠定了坚实的基础。 以β－蒎烯路线生产的香叶醇和橙花醇混合醇产品为原料，采用减压间歇精馏和闪蒸方法，通过添加络合剂提高产品的质量，实现了沸点差仅为 2℃的橙花醇和香叶醇的分离。确定了适宜的变回流比、络合剂用量等条件，获得了含量90%以上的单一产品，橙花醇产品的单程收率为 86%，香叶醇的收率为 60%。 以β－蒎烯路线生产过程的中间产物乙酸芳樟酯混合物、乙酸香叶酯混合物为原料，采用减压间歇精馏，通过添加络合剂，实现了两种热敏性物料的提纯。确定了适宜的变回流比、物料在瓷环填料和θ环金属丝网填料精馏塔中的热分解温度，获得了含量在 95%以上的乙酸芳樟酯产品、乙酸香叶酯产品，产品的单程收率分别为 80%和 68%。更多还原

【Abstract】 ABSTRACT Geraniol, nerol, linalyl acetate and neryl acetate (mixture of genaryl acetate andneryl acetate) are the main synthetic perfume produced from β-pinene. In this article,creative and advanced methods were developed to separate geraniol and nerol fromthe mixture of them. Recovery methods were also developed to obtain linalyl acetateand neryl acetate from different semifinished products respectively. Geraniol, nerol,linalyl acetate and neryl acetate of high quality were gained in high yield. Theexperiment results provide the fundamental data for perfume industry. The mixture produced fromβ-pinene mainly containing geraniol and nerol,whose difference in boiling-point is only 2 C. They were separated by using the omethod of vacuum batch distillation and flash distillation with additives. Suitablereflux ratio and quantities of additives were discussed and determined. Geraniolproduct was gained with purity above 90% and yield up to 86%, and nerol productwas gained with purity above 90% and yield up to 60%. Semifinished products fromβ-pinene contain linalyl acetate, neryl acetate, whichare both heat-sensitive materials. Their purification from different semifinishedproducts was carried out respectively, using the method of vacuum batch distillationwith additives. Suitable reflux ratio and the heat-sensitive temperature were discussedand determined. Linalyl acetate product was gained with purity above 95% and yieldup to 80%, and neryl acetate product was gained with purity above 95% and yield upto 68%.更多还原
