Process and apparatus for making ultra-pure dmso |
| abstract |
One aspect of this invention relates to processes for solidifying dimethylsulfoxide including a step of partially solid-ifying a liquid phase including dimethylsulfoxide and one or more impurities, to form a mixture comprising solid dimethylsulfoxide and a liquid residue. In certain embodiments of the processes of the invention, ultra-high purity DMSO that exceeds the purity spec-ifications for U.S.P. grade DMSO can be produced by employing solidification, fractional solidification and/or melt crystallization processes. |
