摘要: The subject matter of the present invention is a process for the purification of a virtually anhydrous organic liquid other than DMSO alone, in order to decrease its content of alkali and alkaline-earth metal and metal cations, characterized in that it consists essentially in placing this organic liquid in contact with one or more cation exchange resins and in then separating from the resin(s) the purified organic liquid, said resin or at least one of said resins being a sulphonic resin in --SO.sub.3 H or --SO.sub.3 NH.sub.4 form based on a polystyrene-divinylbenzene copolymer having a divinylbenzene content of from 50 to 60% by weight, without taking the sulphonic groups into account.

摘要: To purify a dimethyl sulfoxide (DMSO), this DMSO is placed in contact with an ion exchange resin of sulfonic type in --SO.sub.3 NH.sub.4 form, and the DMSO is then separated from the resin. The DMSO thus obtained has an iron cation content lower than 1 ppb and a sodium cation content lower than 2 ppb.

摘要: This process consists in placing liquid DMSO with a low water content in contact with an ion exchange resin in --SO.sub.3 H form, and then in separating the liquid from the resin.The DMSO thus obtained has a content of iron cation tracer element of less than or equal to 1 ppb and a content of Na cation tracer element of less than or equal to 2 ppb.
