Abstract: In the processing of textile fibers, liquid silahydrocarbons, such as methyltri(decyl)silane, are utilized as textile lubricants. Such lubricants have good high temperature stability.

Abstract: Dispersancy, wear and corrosion properties of lubricating oil are improved by addition of a product made by mixing at about 50.degree.-300.degree. C about 1-20 parts of sulfur with about 100 parts of the condensation product made by reacting a high molecular weight alkylphenol, formaldehyde and a reactive amine. Excess sulfur is preferably removed.

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.
