Refining method of fatty alcohol polyoxyalkylene ether

The invention relates to a method for refining fatty alcohol polyoxyalkylene ether, mainly solves the problem of high VOC (volatile organic compound) residual quantity in a fatty alcohol polyoxyalkylene ether product in the prior art, and adopts the technical scheme that the method for refining the fatty alcohol polyoxyalkylene ether comprises the following steps: (1) carrying out adsorption treatment on the high-VOC fatty alcohol polyoxyalkylene ether by using an adsorbent; and (2) carrying out solid-liquid separation to remove a solid phase so as to obtain low-VOC fatty alcohol polyoxyalkylene ether; wherein the adsorbent is a ZSM-5 molecular sieve or a ZSM-5 molecular sieve loaded with metal elements, the technical problem is well solved, and the method can be used for refining production of fatty alcohol polyoxyalkylene ether. 本发明涉及脂肪醇聚氧亚烷基醚的精制方法，主要解决现有技术中脂肪醇聚氧乙烯醚产品中VOC残留量高的问题，本发明通过采用脂肪醇聚氧亚烷基醚的精制方法，包括：(1)高VOC脂肪醇聚氧亚烷基醚用吸附剂吸附处理；(2)固液分离除去固相得低VOC脂肪醇聚氧亚烷基醚；其中所述的吸附剂为ZSM-5分子筛或负载金属元素的ZSM-5分子筛的技术方案，较好地解决了该技术问题，可用于
