Abstract: Provided are purification methods, comprising: (a) providing an organic solvent and a phenolic peroxide formation inhibitor, wherein the organic solvent has a first boiling point at standard atmospheric pressure (bp1) and the phenolic peroxide formation inhibitor has a second boiling point at standard atmospheric pressure (bp2) that satisfy the following inequality (I): bp2≤(1.10)(bp1)  (I); and (b) heating the organic solvent and the phenolic peroxide formation inhibitor to a temperature causing the organic solvent and phenolic peroxide formation inhibitor to vaporize, and (ii) condensing the vaporized organic solvent and peroxide formation inhibitor to provide a purified mixture of the organic solvent and peroxide formation inhibitor. The methods find particular use in the purification of solvents that are useful in process chemicals for the manufacture of semiconductor devices.

Abstract: An ion exchange resin comprises a crosslinked resin and a salt covalently bonded to a carbon of the resin, wherein the salt comprises a first non-metallic cation and a first counteranion, wherein the first counteranion comprises a second non-metallic cation and a thiosulfate counteranion, and wherein the ion exchange resin is essentially free of metals. The ion exchange resin finds particular use in the removal of impurities from solutions that are useful in the manufacture of semiconductor devices.

Abstract: Provided are containers comprising: an enclosure member; and optionally an article at least partially within the enclosure member. The enclosure member and/or the article comprise an activated polymeric surface, wherein the enclosure member and/or the article comprise an activated polymeric surface, wherein the activated polymeric surface is formed by a method comprising treatment of a sulfonated polymeric surface with a composition comprising a protic acid. Also provided are methods of forming containers. The containers and their methods of formation find particular use in the storage of high purity chemicals useful in the electronics industry, and in the water, pharmaceutical and food and beverage industries.
