NOVELTY - Synthesizing (M1) from unsaturated plant oils a class of molecules compounded with saturated plant oils to obtain a resulting compound that possesses the beneficial properties of both saturated and unsaturated plant oils.    USE - For synthesizing a class of molecules compounded with saturated plant oils from unsaturated plant oils useful as a base stock for a plant-oil based fuel, oil, or lubricant (claimed).    ADVANTAGE - The method utilizes a class of molecules compounded with saturated plant oils possessing low temperature behavior, viscosity and viscosity index; allows for the compounded material to be a base material for fuels, oils and lubricants with low temperature behavior similar to that of fuels, oils and lubricants comprised from pure oleic acid; exhibits superior biodegradability and low ecotoxicity at all stages; reduces the nation's dependence on crude oil by extending the low-temperature capabilities of biodiesel fuels, oils and lubricants making them suitable for year-round use in colder climates and allowing increased supply of feed stocks for these products by using the world's large agriculture supplies of saturated oil fractions of plant oils such as palm oil; produces a blended base material that reduces the cloud point and cold filter plug point of biodiesel made from palm, soybean and other plant-oil feed stocks to equal or exceed the cloud point and cold filter plug point of crude oil based diesel fuel; reduces the pollution load on the air and water; reduces the carbon footprint from the totality of the production and synthesizing cycle; enables the synthesis and blending of plant-oil feed stocks to produce fuel at a cost that is not so burden the price of biodiesel as to be noncompetitive with diesel fuel manufactured from crude oil; enables the production of a line of fuel, oil and lubrication products based on palm, soybean and other renewable, plant-based feed stocks, that have superior performance to that of crude oil and other synthetic oil based materials, enabling the former line of products to command a premium price in the low-temperature application markets.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a base stock (S1) for a plant-oil based fuel, oil, or lubricant comprising any of the set of the following four molecules, the first of which is synthesized from the methyl form of linoleic acid and the remaining three of which are synthesized from the methyl form of oleic acid, according to the method (M1), the set consisting of methyl 9,12-dihydroxyoctadecanoate 10,13-dibutyrate; methyl 10-hydroxyoctadecanoate 9-butyrate; methyl 10-hydroxyoctadecanoate 9-nonanoate; and methyl octadecanoate 9,10-dibutyrate.
