Antiknock agent is a gasoline
additive that works to reduce the engine knocking tendency while trying to
accelerate the octane rating of the fuel. Mixture of gas and air in a
conventional car engine has a problem with igniting too early and when this
happens, it creates a knocking noise.
Commonly used antiknock agents are
tetraethyl lead, ferrocene, toluene, iron pentacarbonyl, isooctane and
methylcyclopentadienyl manganese tricarbonyl. Lead compounds have been used as
an antiknock agent for many years. The most commonly used is tetraethyl lead, a
transparent and highly toxic dense liquid. It easily dissolves in ethyl,
acetone, gasoline and in some other solvents. It boils at around 250°С.

Another commonly used lead antiknock
agent is the tetramethyl lead. It is a liquid with pungent smell and boils at
around 120°С. Due to the relatively low boiling temperature, this substance
spreads more evenly in gasoline fractions. Tetramethyl lead is more stable than
tetraethyl lead at around 700°С. This ensures higher and better efficiency of
the tetramethyl lead as compared to tetraethyl lead in high pressure ratio
internal combustion engine vehicles.
Commonly found drawback of both the compounds
is the high toxicity of the agents, with high impact on the environment and
negative influence on the exhaust gas after treatment devices. Hence, for these
reasons the use of tetramethyl lead and tetraethyl lead is decreasing and
intensive research is carried out for more efficient antiknock agents is in the
pipeline.
Some of the antiknock agents which
have already been tested and used at various times are cyclopentadienyl
manganese tricarbonyl (CMT), methylcyclopentadienyl manganese tricarbonyl (MMT)
and dicyclopentadienyl iron. In terms of higher and better efficiency,
manganese compounds are analogous and iron compounds are inferior to lead. CMT
is a highly volatile crystalline compound of yellow color. It is stable in air
and is easily soluble in organic solvents and is completely insoluble in water.
MMT is a low viscosity liquid of light amber color with a grassy smell and has
a boiling point of 250°С. Ferrocene is a solid crystalline substance and has a
melting temperature of 180°С. Iron pentacarbonyl is a straw color liquid with
boiling temperature of 105°С and freezing temperature of -2°С.
Ferrocenyl dimethyl carbinol is a
crystal powder with melting temperature of 70°С. Organometallic agents create
sedimentation of metals on the walls of combustion chamber. Therefore,
organometallic anti-knock additives are typically used in combination with
materials which convert churly metal oxides into volatile compounds. Due to
high toxicity of lead type anti-knock agents, significant disadvantages and
high cost associated with it, the research for a special material, which does
not comprise any toxic substance, is in the pipeline. Such anti-knock agents
are organic amines containing, xylidine methylaniline and extralyne.
Stringent environmental norms and
increasing investments are some of the key drivers of the antiknock agents
market. However, high cost in the manufacturing of antiknock agents can hamper
the growth of the market. Advancements in new technology bring huge
opportunities for the anti knocks agents market.
