Properties and stability

None yet

Storage method

None yet

Synthesis method

Obtained from the esterification of trifluoroacetic acid and methanol. Mix methanol and trifluoroacetic acid, add concentrated sulfuric acid, reflux for 5 hours, then perform efficient fractionation, and collect the fractions before 50°C. Fractionate again and collect the 40-43°C fraction which is methyl trifluoroacetate. The yield is 80%.

Purpose

Used in organic synthesis.
