摘　　要：介绍了生物质基1,4-丁二异氰酸酯(BDI)合成路线的技术进展。着重介绍了以生物发酵的形式从生物质中获得1,4-丁二酸,再将1,4-丁二酸与氨进行催化、氨化和加氢获得1,4-丁二胺,然后经气相光气化反应获得了BDI的合成方法,并阐述了BDI在医用聚氨酯材料中的应用。The technical progress of biomass 1,4-diisocyanatobutane （BDI） synthetic method was introduced. The synthetic route of BDI began with production of 1,4-succinic acid from biomass by a microbe fermentation process. Then 1,4-butanediamine was formed by catalytic amination of 1,4-succinic acid and following hydrogena- tion. In the next procedure, 1,4-diisocyanatobutane （BDI） was synthesized by vapor phase phosgenation of butane- diamine. The application in medical polyurethane material of BDI was summarized.
