A biodegradable two-cycle oil composition which comprises a C.sub.13 oxo alcohol adipate in admixture with a dispersant and a lubricity agent; it is especially useful for outboard marine engines.

Biodegradable two-cycle oil composition

The present invention provides functional fluid compositions containing a major portion of oil of lubricating viscosity and a novel and synergistic combination of an acylated nitrogen-containing compound having an oil soluble olefinic substituent averaging in carbon number from 8 to 20 and at least one ashless detergent/dispersant.

Synergistic combinations for use in functional fluid compositions

An improved rechargeable, high energy density electrochemical cell comprises an anode, an electrolyte of an ionic salt dissolved in an aprotic organic solvent and a composite cathode structure of a cathode-active material and a metal, the metal being reactive with the cathode-active material to form on the metal an impervious conductive film of a mixture of compounds of the cathode-active material and the metal, which film remains impervious during both charging and discharging. A specific example includes a rechargeable, high energy density battery consisting of a lithium anode, an electrolyte of lithium perchlorate dissolved in dioxolane, and a cathode of titanium disulfide and aluminum.
