升华提纯技术应用和发展趋势

Types and Antioxidative Mechanism of Antioxidants in Petroleum Base Aviation Lubricating Oil

利用升华技术对固体物质进行分离和纯化,可得到传统的方法无法达到的高纯度,且无需溶剂加入,不产生三废,符合绿色化学要求。本文综述了升华提纯技术应用领域、升华提纯研究对象及升华设备的设计,详细总结了升华技术在有机小分子方面的应用及升华机理;并预测了升华提纯技术的发展趋势。

The sublimation technology has been widely applied for separation and purification of the solid materials, by which the high purity can be achieved. Recently much attention has been paid on novel sublimation technolo- gy without solvent and three wastes, which can comply with the requirement of green chemistry. The applications of sublimation purification technology, sublimation purification products and sublimation equipment were described. The application and sublimation mechanism of sublimation technology for organic small molecules were also summarized in detail, and the development trend of sublimation purification technology was also predicted.
