<p>The potassium chloride which generates in a large amount as a by-product of the production of 2,2,2-trifluoroethanol and esters thereof is made suitable for use as a fertilizer. Thus, the by-product potassium chloride is effectively utilizable as a fertilizer to thereby attain a reduction in discard cost and prevention of environmental pollution. The potassium chloride for use as a fertilizer is characterized in that it is the potassium chloride generated as a by-product in a process for producing 2,2,2-trifluoroethanol and/or the 2,2,2-trifluoroethyl ester of an organic carboxylic acid by reacting 1,1,1-trifluoro-2-chloroethane with the potassium salt of the organic carboxylic acid in the presence of an aprotic polar solvent, and in that the content of organic compounds therein is 3 wt.% or lower.</p> |
