摘要： The present invention relates to a process for the production of halogenated butyl rubber and an apparatus for the production of rubber cement for use in the production of halogenated butyl rubber. The process and apparatus permit direct mixing of aqueous rubber slurry with a non-halogenated organic solvent to make a rubber cement solution. The water layer is then separated from the partially dissolved rubber cement and the cement phase is sent for halogenation. The apparatus is an enclosed vessel comprised of at least one dissolving zone and at least one separator zone. The process and apparatus advantageously employ recycle of rubber cement in order to disrupt an interface layer that forms between the water and rubber cement, to thereby improve continuously operation of the process.

摘要翻译： 本发明涉及生产卤化丁基橡胶的方法和用于生产用于生产卤化丁基橡胶的橡胶水泥的设备。 该方法和设备允许水性橡胶浆料与非卤化有机溶剂的直接混合以制备橡胶水泥溶液。 然后将水层与部分溶解的橡胶粘合剂分离，并将水泥相送入卤化。 该装置是由至少一个溶解区和至少一个分离区构成的封闭容器。 该方法和装置有利地使用橡胶粘结剂的再循环，以便破坏在水和橡胶水泥之间形成的界面层，从而改进该方法的连续操作。
