Abstract
Methods and systems for the preparation of chlorohydrins are described herein. The methods and systems incorporate the novel use of a high shear device to promote dispersion and solubility of olefins into the chlorinating phase. The high shear device may allow for lower reaction temperatures and pressures and may also reduce chlorination time.
Claims10
A method of making a chlorohydrin comprising:
- a) contacting an olefin gas with a chlorinating agent in an aqueous phase to form a gas-liquid stream;
- and
- b) flowing the gas-liquid stream through a high shear device so as to form a dispersion with bubbles having an average diameter less than about 1 μm, and form a chlorohydrin.
