【目的】高碳α-烯烃(LAO)是当前化工产品实现高端化转型的关键基础原料之一。因末端双键的高反应活性与碳链长度的可调控性，LAO可以作为共聚单体用于制备聚烯烃弹性体、茂金属聚乙烯等高端聚烯烃，也可作为原料制备油品添加剂、表面活性剂等精细化学品。【方法】本文分类总结了LAO下游产品的制备工艺、技术及产业进展，并对其发展前景进行分析与展望。【结果】近年来，随着高效高选择性LAO制备工艺的逐渐成熟，国内规划/在建LAO产能爆发式增长。【结论】结合产业链合理进行LAO下游产品规划，避免同质化竞争至关重要。
Abstract：【Objective】 Linear alpha olefins(LAO) containing six and more carbon atoms are one of the critical basic raw materials for achieving the high-end transformation of current chemical products. Due to the high reactivity of the terminal double bonds and various lengths of carbon chains, LAO are used as co-monomers to produce high-performance polyolefins including polyolefin elastomers and metallocene polyethylene and as raw materials to synthesize fine chemicals such as lubricant additives and surfactants. 【Methods】This paper categorically summarizes the preparation processes, technologies and industrial progress of LAO-derived downstream products, and analyzes and forecasts their potential development in future. 【Results】In recent years, with the progressive maturation of efficient and highly selective LAO preparation technologies, domestic planned and under-construction LAO production capacity have undergone explosive growth. 【Conclusion】This makes it crucial to rational planning of LAO downstream products in alignment with the industrial chain to mitigate homogeneous competition.
