ABSTRACT:
A solvent for sulfur consisting of a dialkyl disulfide which is free of any basic substance. It is obtained from a commercial dialkyl disulfide by treatment with a reagent capable of eliminating or blocking the basic substances, particularly amines, which are customarily present in such a product. This reagent may be an acid.
The use of the product, after treatment in this manner, for dissolving sulfur which has deposited in the casings of natural gas wells permits the reuse several times of the dialkyl disulfide employed.
