Process for the purification of dimethylsulphoxide (DMSO) |
| abstract |
To purify a dimethyl sulfoxide (DMSO), this DMSO is brought into contact with an ion-exchange resin of sulfonic type in the form -SO 3 NH 4 , then the DMSO is separated from the resin.n n n The DMSO thus obtained has an iron cation content of less than 1 ppb and ansodium cation content less than 2 ppb. |
