process for the continuous production of halogenated butyl rubber and apparatus for producing butyl rubber cement

摘要

Process for the continuous production of halogenated butyl rubber and apparatus for producing a butyl rubber cement The present invention relates to a process for producing halogenated butyl rubber and an apparatus for producing rubber cement for use in the production of halogenated butyl rubber. The process and apparatus allow 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 a closed container comprising at least one dissolution zone and at least one separating zone. The process and apparatus advantageously employ the recycling of rubber cement to disintegrate an interface layer formed between water and rubber cement to thereby improve the continuous operation of the process.
