Chemical reactions on the surface or throughout a thermoplastic fiber present an interesting and challenging reaction engineering problem. This paper presents the design and implementation of a modular multiphase continuous stirred tank reactor for the sulfonation of polyethylene fibers. Polyethylene fiber tows, composed of 1000–6000 filaments, are sulfonated in a series of stirred tank reactors. Fundamental reaction engineering principles are applied to address common batch-to-continuous reactor challenges, such as heat and mass transfer, material balances, and reaction kinetics. The introduction of polymer fibers to a continuous process also requires the solution of practical problems associated with fiber processing. Additional considerations are introduced for designing a reactor system for continuous processing of fiber using liquid with a batch reactor or CSTR contacting pattern in each vessel and containing the effluent gaseous reaction byproducts in a controlled vent stream. The overall sulfonation reaction stoichiometry was determined such that ≈1 mol of SO3 reacts per mol of CH2 fed. Additionally, carbon sulfonation selectivity was determined to be 95–99%, depending on the sulfonation conditions.

用于化学加工聚合物纤维的新型连续多相反应器
表面或整个热塑性纤维上的化学反应提出了一个有趣且具有挑战性的反应工程问题。本文介绍了用于聚乙烯纤维磺化的模块化多相连续搅拌釜反应器的设计和实现。在一系列搅拌釜反应器中，将由1000–6000根长丝组成的聚乙烯纤维丝束磺化。基本反应工程原理适用于解决常见的批间连续反应器难题，例如传热和传质，物料平衡和反应动力学。将聚合物纤维引入连续过程还需要解决与纤维加工相关的实际问题。为设计反应器系统引入了其他考虑因素，该系统用于在每个容器中使用具有间歇反应器或CSTR接触模式的液体，使用液体连续处理纤维，并在受控的排放流中包含流出的气态反应副产物。确定总的磺化反应化学计量，以使≈1摩尔的SO每摩尔CH 2进料反应3。此外，根据磺化条件的不同，碳磺化的选择性被确定为95–99％。
