phase transfer catalysis

[′fāz ¦trans‚fər kə′tal·ə·səs]
(organic chemistry)
Enhancement of the reaction rate of a two-phase organic-water system by addition of a catalyst which alters the rate of transfer of water-soluble reactant across the interface to the organic phase.

Rather than that, the hydrophilic-hydrophobic character of Fe/Ti[O.sub.2] facilitate dibenzothiophene oxidation as a phase transfer catalyst. The coordination of acetic acid and peroxyacetic acid with [Fe.sup.3+] and [Ti.sup.4+] present at the Fe/Ti[O.sub.2] surface which in turn perform a superoxides its surface [208] (Figure 7).
One of the most important strategies to overcome this limitation of water is using phase transfer catalysts (PTC).
He also includes ways of conducting reactions that are less harmful, such as making them in aqueous phase, using phase transfer catalysts, using sonication and microwave technologies, and performing reactions enzymatically and photochemically.
These organic chemicals are mainly used as phase transfer catalysts in chemical reactions as they are soluble in both water and non-polar liquids.
