Description |
The separation of benzene from its mixture with heptane can be achieved by emulsifying
the feed mixture to form an oil-in-water emulsion and then dispersing this emulsion
in kerosene. At high agitation intensity a gel-like structure develops which prevents phase
separation and thereby interferes with the overall mass transfer process. These gel-like
structures have very high viscosities, and show rheopectic behaviour; polarising microscopic
examination of these gel-like structures revealed the existence of liquid crystalline structures
on the surface of the emulsion globules dispersed in kerosene. A possible mode of
development of such liquid crystalline structures is presented. 1-Pentanol added to
kerosene prevents gel formation and assists phase separation. Its action is explained on
the basis of Winsor's theory of solubilization. Typical results for selectivity and benzene
yield are presented.
