What is the structure of TfOH?
Triflic acid, the short name for trifluoromethanesulfonic acid, TFMS, TFSA, HOTf or TfOH, is a sulfonic acid with the chemical formula CF3SO3H. It is one of the strongest known acids. Triflic acid is mainly used in research as a catalyst for esterification.
What is TfOH?
TfOH or triflic acid (trifluoromethanesulfonic acid), is often used in organic synthesis as an acid catalyst. Having a pKa of about -15 it is considered a superacid and is among the strongest of acids.
How to purify triflic acid?
Abstract. The purification process for trifluoromethanesulfonic anhydride is studied. Most of trifluoromethanesulfonic acid (CF3SO3H) can be removed by adding a suitable amount of phosphorus pentoxide. Subsequently, batch vacuum distillation is used to further remove the impurities.
Is TfOH stronger than h2so4?
Trifluoromethanesulfonic acid, also known as triflic acid or TfOH, is a sulfonic acid with the chemical formula CF3SO3H . It is often regarded as one of the strongest acids, and is one of a number of so-called “superacids”. It is about 1000 times stronger than sulfuric acid.
What is the world’s strongest super acid?
Fluoroantimonic acid is the strongest superacid based on the measured value of its Hammett acidity function (H0), which has been determined for different ratios of HF:SbF5.
Which is the most strongest acid?
The world’s strongest superacid is fluoroantimonic acid. Fluoroantimonic acid is a mixture of hydrofluoric acid and antimony pentafluoride. The carbonane superacids are the strongest solo acids.
What is the strongest base in the world?
The title of strongest base in the world belongs to ortho-diethynylbenzene dianion. This superbase has the strongest proton affinity ever calculated (1843 kJ mol−1), beating out a long-standing contender known as lithium monoxide anion.
