Chemical Market Reporter published a full page article on Phase-Transfer Catalysis in the March 15 issue (Fine Chemicals Focus Report page FR8) skillfully written by Clay Boswell. If you are a subscriber with a password, you can read it on the CMR website. This is a good independent article to convince corporate executives who read CMR that PTC programs should be initiated to achieve cost savings to cope with today's competitive market.

Catalyst of the Month - Cetyl
Trimethyl Ammonium Bromide
Inexpensive. Works well when interfacial tension needs to be reduced. Can be introduced as an aqueous solution.
Forms emulsions which may be very difficult to break which can make workup a nightmare.
Reactivity Parameters (Contact PTC Organics for explanation)
Organophilicity C# = 19; Accessibility q-value = 3.06 (forms tight ion pairs)
