ABSTRACT:
Organic material is stabilized by addition of a sulfurized product made by heating a mixture of (a) sulfur and (b) a reaction product formed by reacting in the presence of an alkali metal hydroxide catalyst (i) a mixture of at least two different alkylphenols, each having an unsubstituted ortho and/or para position, and (ii) formaldehyde. Preferably, the reaction product is formed in the presence of a small amount of primary lower alkanol such as methanol. When added to lubricating oil the sulfurized products also impart wear and corrosion inhibiting properties.
