高纯度天然大茴香脑生产技术研究

Study on the Production Process for High Purity Natural Anethole

以八角茴香油为原料,采用静态冷冻工艺冷冻、离心制备得到粗产品,再采用网波不锈钢填料分馏塔对粗产品进行精馏分离得到高纯度大茴香脑(纯度>99%)。产品按国家标准GB23489—2009的要求进行检验。此工艺路线简单、实用,产品品质优良,是生产高纯度天然大茴香脑的新型实用方法。

The high purity natural anethole （〉99%） was obtained by using natural star anise oil as raw material via static freezing, centrifugation and rectification employing fractionation tower filled with stainless steel wave filler. The quality of product was assessed following the standard of GB 23489-2009. The results showed that this process was simple and practi- cal, which could be used as a novel method for producing high purity natural anethole.
