Abstract:
Sulfur containing phosphate esters of thio ethers of phenols and alkoxylated phenols are described, together with method for their preparation and their use as lubricants. The sulfur containing phosphate esters described are represented by the general formula:
WHEREIN: R is an alkyl group of one to 20 carbon atoms, phenyl or aralkyl X IS AN INTEGER OF FROM 1 TO 3 INCLUSIVE N IS AN INTEGER OF FROM 0 TO 50 INCLUSIVE (PREFERABLY 1-20) M IS AN INTEGER OF 1 TO 3 INCLUSIVE Y is hydrogen, methyl or ethyl Z is hydrogen or alkyl, of one to 20 carbons atoms and M is a cation, e.g., H, alkali metal, alkaline earth metal, heavy metal, ammonium or amino. These sulfur containing phosphate esters have valuable lubricating properties and exhibit good anti-wear extreme pressure properties both alone or in water or as additives to other lubricants, such as mineral oils, especially for use as cutting oils or other metal working applications, gear lubricants, etc.

H, ALKALI METAL, ALKALINE EARTH METAL, HEAVY METAL, AMMONIUM OR AMINO. THESE SULFUR CONTAINING PHOSPHATE ESTERS HAVE VALUABLE LUBRICATING PROPERTIES AND EXHIBIT GOOD ANTI-WEAR EXTREME PRESSURE PROPERTIED BOTH ALONE OR IN WATER OR AS ADDITIVES TO OTHER LUBRICANTS, SUCH AS MINERAL OILS, EXPECIALLY FOR USE AS CUTTING OILS OR OTHER METAL WORKING APPLICATIONS, GEAR LUBRICANTS, ECT.
