Abstract

The field of temperatures and conversions in the catalytic process of bulk polymerization of isoprene in apparatuses with a fixed bed of the reaction mixture (polymerization forms) has been studied theoretically and experimentally. It is shown that in an apparatus with a thin layer (3 mm high) the process temperature regime is close to isothermal. In an apparatuses with a higher layer (6 mm high), the approach to isothermal conditions and a corresponding rise in the apparatus productivity is achieved by a stepwise increase in the wall temperature at the time of the drop in the temperature curve of the polymerization. A computational and experimental method is proposed for determining the current conversion of the monomer from the measured values of the current temperature of the reaction mixture.

异戊二烯本体聚合设备效率的提高

摘要

在具有固定反应混合物床（聚合形式）的设备中，异戊二烯本体聚合催化过程中的温度和转化率领域已得到理论和实验研究。结果表明，在具有薄层（3毫米高）的设备中，过程温度范围接近等温状态。在具有较高层（高6mm）的设备中，通过在聚合温度曲线下降时壁温逐步升高，达到等温条件和相应提高设备生产率的方法。提出了一种计算和实验方法，用于根据反应混合物当前温度的测量值确定单体的电流转化率。
