Antiknock agents organolead

W.L. Richardson et al, Ibid, 1023-33 (Organolead antiknock agents - their performance and mode of action) 5) A.D. Walsh, Ibid, 1046-55 (The knock rating of fuels) 6) S. Curry,... 

As indicated above, the largest commercial application of organolead compounds is as antiknock agents. The discovery of the antiknock effect by Midgeley and Boyd 223> led to the present worldwide business in antiknock compounds. Tetraethyllead was sold as early as 1923, but... 

Lead.84 There is an extensive organolead chemistry, but the most important compounds are (CH3)4Pb and (C2H5)4Pb which are made in vast quantities for use as antiknock agents in gasoline. Although lead alkyls and aryls can be made by alkylation of Pb1 compounds,-the two-tetraalkyls are -made otherwise. 

Organolead compounds have been extensively used for many years as antiknock agents in gasoline. Although this use has been banned in developed countries, they are still in use in many developing countries. As a result, enormous amounts of these compounds have been, and still are, discharged into the atmosphere. Therefore, there is a significant... 

Organic derivatives of Group IV find applications in diverse areas. Especially important are the silicone polymers, organotin compounds as stabilizers for plastics and as biocides and organolead antiknock agents for petrol. 

Organolead compounds such as (CH2 = CH)4Pb, Et3Pbl, and organometallic compounds of thallium, selenium and tellurium have been reported as the other antiknock agents [9,27], Now, catalytic converters are attaehed for exhausted gas. These uses are more difficult because deterioration of catalyst of the eonverter inereases.
