Abstract: The present invention provides isothermal multitube reactors suitable for the production of chlorinated and/or fluorinated propene and higher alkenes from the reaction of chlorinated and/or fluorinated alkanes and chlorinated and/or fluorinated alkenes. The reactors utilize a feed mixture inlet temperature at least 20° C. different from a desired reaction temperature.

Abstract: Brominated polybutadiene polymers are recovered from a bromination reaction solution by forming the solution into droplets, thermally stripping the solvent from the droplets, and then washing the resulting particles. The washed particles are then recovered from the washing liquid. The droplets can be dispersed into a gaseous medium such as air and then transferred into a nonsolvent liquid for washing, or can be formed directly into the nonsolvent liquid. The process forms a particulate polymer material that is easily filterable and has low levels of volatile impurities and inorganic salts. Brominated polybutadiene polymers recovered in this manner are often very thermally stable.
