摘　　要：为了解决聚丙烯腈在预氧化过程中反应时间长、效率低、生产成本高的不足,提出了一种新的叔丁基过氧化氢(TBHP)反应处理方案,利用其在高温下分解产生的氧气来引发并加速聚丙烯腈的环化反应,进而减少聚丙烯腈在预氧化反应的时间。根据实际应用表明,新方案能够将环化度提升18.4%,将热失重率降低了20.5%,极大的提升了预氧化质量。In order to address the shortcomings of long reaction time,low efficiency,and high production cost in the pre oxidation process of polyacrylonitrile,a new tert butyl hydrogen peroxide(TBHP)reaction treatment scheme was proposed,which utilizes the oxygen generated by its decomposition at high temperature to initiate and accelerate the cyclization reaction of polyacrylonitrile,thereby reducing the time of polyacrylonitrile in the pre oxidation reaction.According to practical applications,the new scheme can increase the degree of cyclization by 18.4%,reduce the thermal weight loss rate by 20.5%,and greatly improve the quality of pre oxidation.
