Abstract: RECOVERY OF HIGH PURITY BUTADIENE BY LIQUID PHASE SLURRY COMPLEXING IS CONDUCTED WITH AN ACTIVE CUPROUS HALIDE SORBENT SLURRIED IN A PARAFFIN-CONTAINING ORGANIC DILUENT, COUPLED WITH SLURRY STRIPPING AND DESORPTION OF COMPLEXED BUTADIENE IN THE PRESENCE OF THE DILUENT. THE PRESSURES AND TEMPERATURES ARE CAREFULLY CONTROLLED DURING THE COMPLEXING STEP IN ORDER TO PROVIDE A HIGH DRIVING FORCE SO AS TO OBTAIN A HIGH RATE OF BUTADIENE COMPLEXING WITH THE CUPROUS HALIDE, AND TO ACHIEVE A HIGH LOADING OF THE SORBENT WITH COMPLEXED BUTADIENE. IN ADDITION, OTHER NOVEL AND IMPROVED TECHNIQUES FOR RECOVERING THE HIGH PURITY BUTADIENES ARE DISCLOSED.
