Certain partial esters of phthalic acid provide effective rust inhibition for greases and other solid lubricants.

Anti-rust compositions

Certain partial esters and amides provide effective rust inhibition for greases and other solid lubricants.

Borates of certain etherdiamines are provided. These compounds give excellent results when tested in lubricants as friction reducing antioxidants or antirust additives.

Etherdiamine borates and lubricants containing same

Partially borated etherdiamine-acyl sarcosines have been found to be effective multifunctional additives when added to lubricants or liquid fuels. Some of its properties include antirust, antioxidant and friction reducing activities.

Lubricant composition containing a boron reaction product

Nitrogen- and boron-containing products, and their use in lubricants, are disclosed. Particularly, selected diamines are reacted with boron compounds and sarcosines to give partially borated, partial sarcosine salts of the diamine.

Products of reaction of organic diamines, boron compounds and acyl

The cloud point of a hydrodewaxed base stock is reduced by direct sulfurization of the base stock, or by direct sulfurization of the base stock in the presence of a magnesium, calcium or barium compound.

Reducing the cloud point of hydrodewaxed base stocks

The cloud point of a hydrodewaxed base stock is reduced by direct sulfurization of the base stock, or by direct sulfurization of the base stock in the presence of a magnesium compound.

Organic acid esters and oils of lubricating viscosity which have been oxidized and phosphosulfurized in the presence of lime or zinc oxide provide excellent antiwear/EP characteristics to metal forming lubricants containing same.

Metal forming lubricants

Phosphorus- and sulfur-containing metal salts are prepared by reacting a mixture comprising a metal oxide and a hydrocarbon in the presence of an oxidizing gas and then reacting this product with a phosphorus sulfide. The invention provides lubricant compositions containing the product.
