5-Sodiosulfoisophthalic acid Use and Manufacturing
NaSIPA in Acetic Acid Water [0058] To a 2000 ml, round-bottom flask is added 691 , 5 grams of acetic acid, 83.5 g of DI water, 72.91 g of sodium hydroxide (50percent in water) and 250 g of HSIPA (94.4percent Assay; 4.4 percent Water; and 0.85percent Strong Acid as HThe process according to the invention was used to make the sodium salt of 5 sulfoisophthalic acid (NaSIPA). [0067] To a 1000 mL round-bottom flask is added 450 grams of an aqueous HSIPA solution (approximately 29.12percent HSIPA and 29.9percent sulfuric acid). Caustic (NaOH, 50percent, 42.6 grams) was added slowly and the mixture was heated to reflux at about 100 to 120° C. The resulting slurry was cooled to 85° C. Four drops of 35percent hydrogen peroxide were added and the batch was cooled to 25° C., filtered on a sintered glass funnel and washed twice with glacial acetic acid (70 grams for each wash). The product was dried in a 100° C. vacuum oven to give 140.9 grams of white solid. The product assayed as follows:
