Incompatibility gasoline

These compounds have been incorporated in the gasolines of the entire world since 1922. Their use will disappear with the general acceptance of catalytic converters with which they are totally incompatible. 

Already these early results have shown the incompatibility of heavily leaded gasolines with catalysts designed to achieve a rather moderate goal of automotive emission control. The added stringent requirements of the... 

Note Nonpolar hydrocarbon solvent mild, gasoline-like odor soluble in hydrocarbons, alcohols, organic halides, acetone, benzene flammable moderately toxic by inhalation, ingestion, or skin absorption, may be narcotic at high concentrations reacts with oxygen (air) at elevated temperatures decomposes upon heating incompatible with strong oxidants. Synonyms benzene hexahydride, hexameth-ylene, hexanaphthene, hexahydrobenzene. 

The relative contribution of mobile source emissions to atmospheric lead levels over the next decade is expected to decrease slightly for two reasons (1) the Federal government s imposition of a phasedown of lead content in gasoline, as called for in regulations promulgated in September 1976 (43) and (2) the incompatibility of leaded gasoline and the catalytic converter introduced in late 1974 for control of regulated (HC, CO, NO,) pollutants (44,45). 

Additives are chemical compounds intended to improve some specific properties of gasoline or other petroleum products and can be monofunctional or multifunctional (Table 5.4 ASTM D-2669). Different additives, even when added for identical purposes, may be incompatible with each other and may, for example, react and form new compounds. Consequently, a blend of two or more gasolines, containing different additives, may form a system in which the additives react with each other and so deprive the blend of their beneficial effect. 

Furthermore, the higher aromatics content and the possible presence of oxygenates in motor gasoline can induce solvent characteristics that are unsuitable for seals, gaskets, fuel lines, and some fuel tank materials in aircraft. Motor gasoline may also contain additives that could be incompatible with certain in-service aviation turbine fuel (ASTM D-4054, ASTM D-4307). For example, alcohols or other oxygenates can increase the tendency for the fuel to hold water, either in solution or in suspension. 

CASING HEAD GASOLINE (8006-61-9) Forms explosive mixture with air (flash point <0°F/<-18°C). Violent reaction with oxidizers, fluorine. Incompatible with nitric acid. Flow or agitation of substance may generate electrostatic charges due to low conductivity. 

Unmatched systems are two or more entirely incompatible systems put together, for example a diesel fuel system installed in a car with a gasoline internal combustion engine.

In some areas, methanol lacks a characteristic required of a fuel For example, as previously discussed, methanol bums with a virtually nonluminous flame, constituting a hazard that may need to be addressed with an additive. In other areas, methanol suffers drawbacks because of its incompatibility with gasoline.
