天然生物质腰果壳液的分离研究进展

Progress in Separation of Natural Cashew Nut Shell Liquid

天然生物质腰果壳液中的主要组分腰果酚可替代石油酚,广泛应用于油田、涂料等领域;腰果酸和强心酚具有较高的反应活性,通过化学改性,可广泛应用于医药和材料领域,且各组分均具有很好的生物降解性。然而,各组分的精确分离成为腰果壳液广泛应用的关键。本文通过对国内外腰果壳液的分离方法的系统总结,综述了腰果酚、腰果酸、强心酚的精细分离方法以及其优缺点,并对各组分的应用前景进行了简单的介绍和展望,为这类来源广泛的生物质的应用提供理论支持。

Cardanol anacrdic acid and cardol are the major components of natural cashew nut shell liquid( CNSL) and possess good biological degradability. As substitute for petroleum phenol,cardanol has been widely employed in the oil field,coating field,and so on. Anacrdic acid and cardol exhibit high chemical activities,so they can be extensively used in the pharmaceutical and polymer industries through chemical modification. However,their separation and purification from CNSL is the key for their applications. In this paper,some present separation methods for CNSL are summarized,and their applications are prospected.
