Abstract
A method for dissolving a deposit of elemental sulfur by contacting the deposit with dialkyl disulfides catalyzed with an aliphatic amine in which a small amount of sulfur is added to the disulfide amine mixture before it is used as a sulfur solvent. The small percentage of sulfur added increases the rate at which the disulfide dissolves such sulfur deposit.
