BDNPA/F增塑剂的合成及其发展

Review on Synthesis of BDNPA/F Plasticizer and its Development

介绍了BDNPA/F的合成方法及进展。美国早期开发出氧化硝化法和氯化硝化法两种制备BDNPA/F的方法,其中氯化硝化法适于大规模生产时使用。随着环保意识的提高,美国聚硫公司最近开发出了环境友好的BDNPA/F的合成工艺。针对BDNPA/F中BDNPA的热和化学稳定性比较差的问题,人们已提出了几种改进方案,其中一定组成的BDNPF/DNBPF/BDNBF增塑剂的能量与BDNPA/F相当,但热和化学稳定性比BDNPA/F好,具有良好的开发应用前景。

The synthetic methods and progress of bis （ 2,2-dinitropropy] ） acetal/bis （ 2,2-dinitropropy] ） formal （ BDNPA/BDNPF, BDNPA/F） plasticizer were introduced. The oxidative-nitration route and the chlorination-nitration route were developod by USA. The chlorination-nitration route is suitable for larse scale production. More environmental friendly synthetic technology for BDNPA/F was recently developed by Thiokol corporation. Thermal and chemical stabilities of BDNPA were worse than that of BDNPF,several improved compositions were proposed, Energy of DNBPF/BDNBF composite plasticizer is equal to that of the BDNPA/F mixture, but its chemical stability is better, therefore it has great potential application.
