Process for polymerizing vinyl chloride using a reflux condenser
Abstract
Abstract FFIG-01 THIS INVENTION PROVIDE AN IMPROVED PROCESS FOR POLYMERIZING VINYL CHLORIDE IN AN AQUEOUS MEDIUM USING A REFLUX CONDENSER. THE IMPROVEMENT COMPRISES (1) DURING THE CONDENSATION PERIOD SPRAYING A COATING OF WATER ON THE INNER SURFACES OF THE COMDENSER TO INHIBIT THE FORMATION THEREON OF POLYMERIZED VINYL CHLORIDE PARTICLES, AND (2) SPRAYING WATER IN THE PATHOF AND IN A DIRECTION COUNTER-CURRENT TO THE FLOW OF VINYL CHLORIDE VAPORR AS IT PROGRESSES FROM THE REACTOR TO WITHIN THE CONDENSER THEREBY TO ASSIST IN CONDENSING THE VINYL CHLORIDE FOR RETURN TO THE REACTOR. THE SPRAY MAY INCLUDE A DEFOAMER TO REDUCER THE TENDENCY OF CARRYOVER OF POLYMER INTO THE CONDENSER TUBES.
