Abstract
Monoalkylated phenoxathins are high-temperature stable lubricant fluids having extreme pressure and antiwear properties, additive solubility and inherent EP/antiwear properties. These novel phenoxathin fluids may also be used as additives in other lubricant fluids and are prepared by alkyating a phenoxathin in the presence of an acidic zeolite catalyst.
