tetraethyl lead

Later authors credit both methods of preparation with producing tetraethyl lead.

Additionally, tetraethyl lead was used as a gasoline additive until the 1990s.

Tetraethyl lead was once widely used to improve the combustion properties of gasoline.

Other alternatives to tetraethyl lead tend to cost more for the same octane enhancement.

This fuel is essentially 100LL with the tetraethyl lead omitted during the production process.

In the 1960s, only two grades of gasoline were for sale, a premium and a regular type, both containing tetraethyl lead.

Regardless, tetraethyl lead remained commercially unused for many years.

In some cases, organometallic forms, such as methylmercury and tetraethyl lead, can be extremely toxic.

Tetraethyl lead and the "looney gas building"

Tetraethyl lead works as a buffer against microwelds forming between the hot exhaust valves and their seats.

At G.M., he developed tetraethyl lead, which increases octane in motor fuel.

Meanwhile, every other major producer has stopped making the additives, known as tetraethyl lead, or TEL.

He was among the first to describe the dangers of tetraethyl lead, which was used for several decades as an anti-knock additive in petrol.

Tetraethyl lead was long used to lubricate and cushion an engine's valves, at the same time that it satisfied the need for higher octane.

Now Dr. Cunningham and his associates have planted a small plot in the defunct tetraethyl lead plant.

Not tetraethyl lead; not carbon monoxide; not nitrogen oxides - just water.

It is added for three reasons: to increase octane enhancement, to replace banned tetraethyl lead, and to raise the oxygen content in gasoline.

For example, because lead itself deactivates free radicals in the gasoline-air mixture, tetraethyl lead was once commonly added to gasoline.

Replies: First of all, the English name for "tetra etilo de plomo" is "tetraethyl lead."

Gasoline obtained from coal by the Karrick process combined with cracking and refining is equal in quality to tetraethyl lead gasolines.

Another "marker" used to determine approximately when a leak occurred are additives like tetraethyl lead - the "lead" in leaded gasoline.

Replies: "Way back when", (before about 1960), tetraethyl lead was formulated into gasoline to cushion engine valves, thereby extending engine life.

As visionary of the company, it was Pew who was behind the effort to develop gasoline without tetraethyl lead, creating Blue Sunoco.

As a consequence, gasoline often contained several percent benzene before the 1950s, when tetraethyl lead replaced it as the most widely used antiknock additive.
