ABSTRACT:
Sulphur-containing substances are derived from mono- or polyethylenic hydrocarbons by sulphurization using elemental sulphur in the presence of at least one alkali or alkaline-earth metal hydroxide and at least one glycol or polyglycol, or glycol or polyglycol monoether and/or water. Sulphur-containing substances, which may contain 20% to 70% by weight of sulphur, are generally soluble in lubricants to improve antiwear and extreme pressure properties. They can also be used as sulphurization agents, in particular for preparing catalysts for refining petroleum products.
