    Abstract: A composition is disclosed for dissolving sulfur and preventing or removing sulfur plugs from sour gas and oil wells or other conduits through which sulfur bearing liquids flow which comprises a major proportion of a liquid or gaseous mercaptan, a minor proportion of a catalyst which is a substantially water-insoluble amine, and minor amount of an activator which is a compound of the formula:

    where R is hydrogen, alkyl, aryl or alkaryl and the alkyl moieties have from 1 to 24 carbon atoms, and x and y are independent values between 0 and 24 provided that x or y is at least 1; a method is also disclosed wherein said composition in an effective amount is injected into a conduit to prevent or remove sulfur plugging, and the composition containing dissolved sulfur is optionally recovered.
