Abstract: Fluorocarbon additives are provided which may be introduced into fibrous articles to provide improved anti-soiling, anti-stain, water repellency and/or oil repellency properties which resist abrasion and laundering. The additives may be introduced into the fibrous article by incorporation into the melt prior to extrusion of the fiber, or alternatively absorbed into a previously formed fibrous article by contacting the article with a liquid medium containing the additive, optionally followed by annealing the treated article to further improve the article's surface properties.

Abstract: Cl process for removing phosphate ion from an aq. soln. contg. fluoride and phosphate ion comprises adding to the soln. at a pH >=8.5 a water-soluble Ba cpd. in an amt. at least stoichiometrically equiv. to the phosphate ion, and sepg. the resulting Ba phosphate ppte. The main use of the process is in the purificn. of solns. contg. inter alia, H2SiF6, obtained by the absorption of den. gases produced in the mfre. of phosphoric acid; pptd. silica may be ioncomitantly removed. Aq. ammonia is pref. used to achieve the required pH, desirably 9.0.
