来源：市场资讯 （来源：华经产业研究院） 需求端看，正丙醇下游66%是醋酸正丙酯、医药中间体、农药中间体、溶剂占比12%、10%、9%，其他 领域应用占比为3%。 近年来，在下游需求市场驱动下，我国部分企业开始投资新建正丙醇产能，行业整体生产能力呈现上升 态势，市场供应规模也日益增加。据统计，2024年我国正丙醇行业产能为31万吨，产量为20.08万吨， 需求量为22.54万吨。 由于国内产能不足，正丙醇长期依赖进口，自2020年7月17日起，中国商务部对原产于美国的进口正丙 醇实施了反倾销制裁，正丙醇进口量显著下降，据统计，2024年我国正丙醇进口量为3.86万吨，出口量 为1.4万吨。目前反倾销尚未结束，在此基础上，受对等关税政策影响，进口正丙醇价格或将进一步攀 升，从而带动国内正丙醇销售价格上行。 国内正丙醇生产企业较少，截至2024年全国产能在31万吨左右，其中三维化学产能10万吨，占比 32.26%，居于全国领先。鲁西化工产能8万吨，占比25.81%，巨化股份产能5万吨，占比16.13%，南京 荣欣产能4万吨，占比12.9%。 华经产业研究院研究团队使用桌面研究与定量调查、定性分析相结合的方式，全面 ...
