Abstract
A composition comprising a base and an alkoxylated compound selected from an alkoxylated alcohol and alkoxylated mercaptan is disclosed. The composition can be used to catalyze the reaction of a mercaptan and an elemental sulfur to produce a polysulfide compound. The polysulfide compound can be further treated with an alkylene oxide to reduce the mercaptan sulfur content of the polysulfide compound.
