By making use of potassium chloride by-product thatnis produced in large amounts in a production process ofn2,2,2-trifluoroethanol and its esters, potassium chloridensuitable for use as a fertilizer is produced. Accordingly,nthe present invention makes it possible not only toneffectively make use of the potassium chloride by-product,nbut also to reduce the cost in processing the wastenproducts and prevent environmental pollution. n The present invention provides a potassium chloridenby-product for use as a fertilizer, the potassium chloridenby-product produced in a process in which 1,1,1-trifluoro-2-chloroethanenis reacted with a potassium salt of annorganic carboxylic acid in the presence of polar aproticnsolvent to form 2,2,2-trifluoroethanol and/or 2,2,2-trifluoroethylnester of organic carboxylic acid, thenpotassium chloride by-product being characterized in thatnit contains organic materials in an amount of 3wt% or less. |
