Triflic acid belongs to the class of superacids, it is the strongest Bronstedt acid available at industrial scale. It is used as an acidic catalyst in many organic synthesis reactions(alkylation, esterification, etherification, acylation, isomerization, ethoxylation, cyclization, cationic rearrangement, etc .) and in cationic polymerization. The triflate anion is widely used as intermediate in organic synthesis, since it is an excellent leaving group (up to 30,000 times more effective than tosylate). Due to its unique properties, the triflate anion is also an excellent anion for ionic liquids.
Triflic acid is used:
– as an acidic catalyst in many reactions in organic synthesis and in cationic polymerization
– for electronic applications like liquid crystals and batteries
– as synthesis intermediates for chemical and pharmaceutical applications
