А queous solutions of propylen glycol methyl ether containing 40-50 % vol. (42-52 % wt.) of water were investigated as extraction agent of sulfoxides. Extent of extraction of sulfoxide makes 89,2-93,17 %, the content of sulfoxide sulfur in concentrate is 8,1-9,0 % wt., indicating a high extraction capacity of propylene glycol methyl ether.
