合成聚异戊二烯胶乳制备中蒸馏操作工艺的优化
Optimization of Atmospheric Pressure Continuous Distillation Process of Isoprene Latex
摘要
Abstract
This study systematically investigated the solvent removal process from isoprene emulsion containing solvents,a critical step in synthetic polyisoprene latex production.The research focused on analyzing the effects of continuous distillation parameters,including distillation temperature,average residence time,solvent removal efficiency,and solid content,while comparing different distillation configurations.The results indicated that when the optimal distillation temperature in a single kettle ranged from 70～72℃and the average residence time was between 5.5～6.5 h,the solvent removal rate could reach 65%～75%,with an outlet solid content of approximately 9%and a gel content of less than 2%.By adopting a continuous distillation process that combined multi-stage series and parallel configurations(e.g.,three parallel kettles in series with a fourth kettle,with the temperature in all four kettles not exceeding 78℃),it was possible to effectively enhance the utilization rate of distillation equipment and the processing capacity of latex while maintaining stable process parameters.This study provides technical references for optimizing solvent removal processes in industrial production.关键词
