生物质衍生的丁烯内酯作为丙烯酸酯的绿色替代品,在涂料中具有可调性能。近世纪来,基于石油化工的单体如丙烯酸酯已被广泛用作涂料、树脂和油漆的基础。开发可持续的替代品,将绿色化学的原理整合到起始材料、合成过程和产品功能中,为科学和社会带来了巨大的挑战。在这里,我们报告烷氧基丁烯内酯作为丙烯酸酯的生物基替代品和高性能涂料的形成。从生物质衍生的糠醛开始,在流动反应器中使用可见光和氧气进行环境友好的光化学转化,提供烷氧基丁烯二醇单体。随后进行自由基(共)聚合,从而产生具有可调性能的涂层,用于玻璃或塑料等不同表面。其性能可与目前的石化衍生工业涂料相媲美。
Biomass-derived butenolides are presented as green alternatives for acrylates in coatings with tunable properties. For almost a century, petrochemical-based monomers like acrylates have been widely used as the basis for coatings, resins, and paints. The development of sustainable alternatives, integrating the principles of green chemistry in starting material, synthesis process, and product function, offers tremendous challenges for science and society. Here, we report on alkoxybutenolides as a bio-based alternative for acrylates and the formation of high-performance coatings. Starting from biomass-derived furfural and an environmentally benign photochemical conversion using visible light and oxygen in a flow reactor provides the alkoxybutenolide monomers. This is followed by radical (co)polymerization, which results in coatings with tunable properties for applications on distinct surfaces like glass or plastic. The performance is comparable to current petrochemical-derived industrial coatings.
