    Abstract: An aviation 100LL fuel additive formulation for lead scavenging which mitigates the detrimental effects of lead, cleans up the combustion chamber and also allows shipping and distribution by common carrier, such as UPS or FedEx. A fuel additive composition is described for aviation 100 octane Low Lead fuel, containing: (1) glycol ether 10 to 90% by volume; (2) tricresyl phosphate 5 to 10% by volume; and, (3) Polyetheramine 15 to 30% by volume. The described composition has a flash point above 141 degrees F. to enable safe shipping by common carrier. The described composition also contains polyetheramine to create a mixture which is shown to be effective in preventing plug fouling by lead and be effective in reducing combustion chamber deposits, thus providing a smooth running engine during ground operations.

    Abstract: A process for preparing a paraffin inhibitor formulation comprising (a) preparing a mixture comprising a waxy paraffin inhibitor component having a melting point of >0° C. and an emulsifier component, wherein the mixture is prepared at a first temperature range above the melting point of the waxy paraffin inhibitor; (b) adding water to the mixture to produce an o/w emulsion; and (c) cooling the o/w emulsion to a temperature in a second temperature range which is below the melting point of the waxy paraffin inhibitor. The mixture prepared in step (a) may further comprise water to produce a w/o emulsion, the water being present in a proportion by weight that is lower than the sum of the proportions by weight of the paraffin inhibitor and the emulsifier component. The process may further comprise (d) adding an at least partially water-miscible organic solvent in which the paraffin inhibitor is insoluble.
