Sunflower (Helianthus annuus L.) oil remains under-utilised albeit one of the major seed oils produced world-wide. Moreover, the high oleic sunflower varieties make the oil attractive for applications requiring high temperature processes and those targeting the C=C double bond functionality. Herein an overview of the recent developments in olefin metathesis of sunflower-based feedstocks is presented. The improved performance of olefin metathesis catalysts leading to high turnover numbers, high selectivity and catalyst recyclability, opens new opportunities for tailoring sunflower-based feedstocks into products required for possible new niche market applications. Promising results in biofuel, biopolymers, fragrances and fine chemicals applications have been reported.
向日葵（Helianthus annuus L.）油虽然是世界上主要的种子油之一，但仍未得到充分利用。此外，高油酸向日葵品种使这种油在需要高温处理的应用和针对 C=C 双键功能的应用中具有吸引力。本文综述了基于向日葵的原料中烯烃复分解的最新进展。烯烃复分解催化剂的性能得到了改善，从而实现了高转化数、高选择性和催化剂可回收性，为将基于向日葵的原料定制成可能的新利基市场应用所需的产品开辟了新的机会。在生物燃料、生物聚合物、香料和精细化学品应用中已经报道了有前景的结果。
