Cellulosic particles, for example wood particles, stored in a pile are preserved by contacting the particles with a thiocarbonate composition.

Preservation of wood chips

Encapsulating particles of solid thiocarbonate salts, esters and complexes with air- and water-impermiable coatings produces compositions having long-term stability.

Stabilized solid thiocarbonate compositions and methods for making same

Additives comprising an adduct of a calcium salt of a thiocarbonic acid and calcium hydroxide are useful in lubricants to enhance both the extreme pressure/anti-wear and anti-oxidation capabilities thereof. The lubricants are preferably oils of lubricating viscosity, which may be thickened to a grease-like consistency with one or more oil thickeners and contain from about 0.1 to about 20 weight percent of said adduct.

Lubricating compositions

Additives containing a salt or complex of trithiocarbonic acid are useful in lubricants to enhance the extreme pressure/anti-wear and anti-oxidation capabilities thereof. The lubricants are preferably oils of lubricating viscosity, which may be thickened to a grease-like consistency with one or more oil thickeners, and contains from about 0.1 to about 20 weight percent of said additives.

Extreme pressure lubricating compositions and method of using same

Additives comprising a salt or complex of tetrathiocarbonic acid are useful in lubricants to enhance both the extreme pressure/anti-wear and anti-oxidant capabilities thereof. The lubricants preferably are oils of lubricating viscosity, which may be thickened to grease-like consistency with one or more oil thickeners, and contain from about 0.1 to about 20 weight percent of said additives.
