<p>The invention provides a process for the preparation of 2,2,2-trifluoroethanol by reacting a Ϝ-hydroxybutyric acid salt with 1,1,1-trifluoro-2-chloroethane which brings about an increase in the yield of 2,2,2-trifluoroethanol and enables easy separation of by-product salts and recovery and recycling of an aprotic polar solvent. The invention relates to a process for the preparation of 2,2,2-trifluoroethanol by reacting a Ϝ-hydroxybutyric acid salt with 1,1,1-trifluoro-2-chloroethane in an aprotic polar solvent, characterized by using a Ϝ-hydroxybutyric acid salt having a 4,4’-oxydibutyric acid content of 6 wt% or below.</p> |
