The solvent is heated and introduced at a point within the production string at which the sulfur would normally begin to precipitate from the produced gas stream. Xylene is used in some glue. It was named after xylong, the Greek word for wood, because it was found in crude wood spirit. Because xylene is so efficient at removing fats, any contact with the skin will have the same effect. This can lead to drying and cracking of the skin and dermatitis. Fluid Phase Equilibria 2011, 312 , 31-36. Increasing the solubilization time from 3 hours to 24 hours did not improve the sludge solubilization process. Of the solvents mentioned in your question, sulfur (S) only dissolves well in carbon disulfide (CS2) and only very little to little from more polar organic solvents, like alcohol or acetone to nonpolar solvents, such as benzene or toluene. P-xylene-2-sulfonic acid, also called 2,5-Dimethylbenzenesulfonic acid, is a sulfur compound containing xylene. The principal mechanism of detoxification is oxidation to methylbenzoic acid and hydroxylation to hydroxylene.
