摘要
研究了一种高浓度氧气含量的分析方法。采用QF1904型奥氏气体分析仪器,利用气体被化学试剂选择性吸收的性质,根据吸收前后混合气体体积变化,测定出氧气含量。该方法简便、快速。
On polypropylene production unit,the main factors affecting the polymerization of propyl-ene were analyzed.Increasing the efficiency of the polymerization reaction of raw materials by reducing the impurity content,selecting suitable catalyst,modifiers,and the added ratio of triethylaluminum as well as selecting a suitable reaction temperature,reaction pressure and other measures etc was proposed.The meth-od is simple and fast.
