<p>A liquid lubricant comprising a blend from about 50 percent to about 90 percent by weight of an ester of a monohydric alcohol having from about 10 to about 18 carbon atoms and a monocarboxylic acid having 12 to 24 carbon atoms, and from about 10 percent to about 50 percent by weight of a fat liquid at room temperatures, such as fish oil. One or more of the monohydric alcohol, monocarboxylic acid, and liquid fat have sufficient carbon-to-carbon unsaturation to impart to the blend an iodine number up to about 140. The lubricant has a balance of properties adapting it to be used as a substitute for sperm oil, for example, a pour point below 50.degree.F. and a S.U.S. viscosity at 100.degree.F. within the range of about 60 to about 120. The blend may be used as such or chemically combined with sulfur, chlorine or other halogens, phosphorous, and the like.</p> |
