Procedure

To a 4-liter (L) flask was added 2370 grams (g) of hot water, 250 g of 50 percent by weight NaOH, 30 g of NaCl, and 350 g of wet 4-amino-3,5,6-trichloropyridine-2-carboxylic acid (80 percent). The solution was stirred for 30 minutes (min), filtered through a 1 micron polypropylene film, and transferred to a 5-L feed circulation tank. This solution weighed 3000 g and contained 9.3 percent 4-amino-3,5,6-trichloropyridine-2-carboxylic acid, 2.0 to 2.5 percent of excess NaOH, and 1.0 percent of NaCl.
