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.
Claims14
A method for producing sulfolene, the method comprising
- contacting butadiene with sulfur dioxide wherein sulfur dioxide gas is provided as gas bubbles having a mean diameter less than about 5 μm, at a pressure less than about 500 psig and a temperature less than about 150° C.
A system for the production of sulfolene from butadiene, the system comprising;
- an external high shear mixer which produces a dispersion of sulfur dioxide in liquid medium, the dispersion having an average bubble diameter of less than about 100 nm;
- and
- a reactor wherein sulfolene is produced from the reaction of sulfur dioxide with butadiene;
- the reactor fluidly connected to the outlet of the external high shear mixer.
In a system for production of sulfolene from hydrogen sulfide and butadiene, including a reactor operating at conditions suitable for the cycloaddition reaction of butadiene with sulfur dioxide to yield sulfolene, the improvement comprising:
- inserting a high shear mixer upstream of said reactor, said high shear mixer comprising a liquid inlet and a sulfur dioxide gas inlet, and producing a high shear feed stream to said reactor unit wherein said feed stream comprises gas bubbles of no more than about 100 nm in diameter.
