ABSTRACT:
Use of a high shear mechanical device incorporated into a process for the production of sulfolene as a reactor device is capable of decreasing mass transfer limitations, thereby enhancing the sulfolene production process. A system for the production of sulfolene from butadiene and sulfur dioxide, the system comprising a reactor and an external high shear mixer the outlet of which is fluidly connected to the inlet of the reactor; the high shear mixer capable of providing a dispersion of sulfur dioxide gas bubbles within a liquid, the bubbles having an average bubble diameter of less than about 100 μm.
