Method for purifying hydroxyl silicone oil

The invention provides a method for purifying hydroxyl silicone oil. The method comprises: 1, diluting hydroxyl silicone oil with a solvent to obtain a mixed solution; 2, carrying out centrifugal separation on the mixed solution, and reserving supernatant; 3, introducing the supernatant into an adsorption column filled with an adsorption material, and carrying out adsorption column chromatographic separation to obtain a hydroxyl silicone oil solution; and 4, distilling the hydroxyl silicone oil solution to remove the solvent to obtain purified hydroxyl silicone oil. The method is simple in process and convenient to implement, greatly reduces the purification cost of the hydroxyl silicone oil, and is suitable for industrial production. 本发明提供一种羟基硅油的纯化方法，包括以下步骤：步骤一、将羟基硅油用溶剂进行稀释，得到混合溶液；步骤二、将混合溶液离心分离，留取上层液；步骤三、将上层液通入填装有吸附材料的吸附柱，进行吸附柱层析分离，得到羟基硅油溶液；步骤四、将羟基硅油溶液进行蒸馏以去除溶剂，得到纯化后的羟基硅油。本发明方法过程简单、实施方便，大大降低了羟基硅油提纯的成本，适用于工业化生产。
