摘要
介绍了以叔丁基过氧化氢(TBHP)和新癸酰氯(NDCL)为原料,利用微反应器的高效混合和强换热能力,安全、高收率生产高纯度过氧化新癸酸叔丁酯的工艺,探究了碱浓度、反应温度、停留时间对反应过程的影响.结果表明:最佳试验条件为 KOH∶TBHP∶NDCL=1.35∶1.2∶1(摩尔比),碱质量分数为 20%,反应温度为 70℃,停留时间为 1 min,收率为 91.78%.
Abstract
The process was introduced of safely producing high purity tert butyl peroxydecanoate at high yield using tert butyl hydroperoxide and neodecanoyl chloride as raw materials,utilizing the efficient mixing and strong heat exchange capacity of microreactors.The effects of alkali concentration,reaction temperature,and residence time on the reaction process were investigated.The results showed that the optimal experimental conditions were KOH∶TBHP∶NDCL=1.35∶1.2∶1(molar ratio),alkali mass fraction of 20%,reaction temperature of 70℃,residence time of 1 min,and the yield was 91.78%.
