What does PTC stand for?

In comparison to metal-catalyzed reactions, phase transfer catalysis has several advantages, including its water-tolerable properties with operational simplicity by using environmentally-benign catalysts, and the easy separation of products due to its biphasic nature.

In addition to these more familiar applications, ionic liquids have been reported as highly versatile media for use as electrolytes in various electrochemical devices such as solar cells (13, 14) and lithium batteries (11), as electrochemical capacitors (15), matrices for MALDI mass spectrometry (16, 17), surfactants (18), electropolishing agents (13), phase transfer catalysis (19), and as highly resilient media in radiation intensive environments (20).
