创新植物油多元醇结构及制造工艺 中化新网讯 近日，南京工业大学生物与制药工程学院郭凯教授团队的发明专利"一种植物油多元醇及其 制备方法与应用"获第二十五届中国专利奖金奖。该项目创新植物油多元醇结构，开发了高效制备植物 油多元醇制造工艺，生产出生物基聚氨酯新材料，并实现万吨级规模产业化。 聚氨酯由多元醇和异氰酸酯聚合而得，其原料对石化资源依赖重，部分高端产品进口依存度高，被国外 企业把持，产品价格居高不下。"开发生物基聚氨酯及单体料多元醇可对石化产品形成补充，且高效固 碳。"郭凯介绍道。然而，生物基聚氨酯全产业链面临着严重挑战，尤其是高性能单体料植物油多元醇 产品存在空白，市场现有的多元醇产品难以满足高端应用需求且成本高。与此同时，高效制造植物油多 元醇的技术及装备匮乏，传统的釜式反应难以实现高效生产。 为此，郭凯团队以植物油为原料，经官能团衍生活化开发植物油多元醇系列产品。团队成员、该校生物 与制药工程学院副院长方正教授介绍说，在此过程中，团队采用微化工及过程放大技术，在温和条件及 较短反应时间内即能完成相关反应过程，且反应选择性显著提高，使设计的结构能够精准构建，而传统 釜式反应则无法精确完成此反应过程。 ...
