The cause for automatic explosion in butadiene systems, that is the formation of butadiene polyperoxide due to the entry of oxygen into the system, is verified through experiments. 用实验分析验证了丁二烯系统自动爆炸的原因,即氧气进入系统形成了丁二烯聚过氧化物。
The yield of benzoic acid could be improved by increasing operational temperature and catalyst dosage which could accelerate cleavage of polyperoxide to form benzoic acid. 提高反应温度和增加催化剂浓度都能改变口-甲基苯乙烯的聚过氧化物的稳定性,使其开裂并最终转化为苯甲酸。
Cases of butadiene polyperoxide formation and distribution of oxygen in the system in the factory have been investigated. 考查了本厂丁二烯过氧化自聚物的生成情况及系统中氧的分布情况。
Experiment results proved that formation of polyperoxide and polymerization of butadiene were concerned with oxygen and active seeds. They were also influenced by presence of styrene and acrylonitrile. 实验证实:丁二烯过氧化自聚物的生成及丁二烯的聚合反应与氧及活性种子有关,也受苯乙烯与丙烯腈存在的影响;
