Methylcyclopentadienylmanganese tricarbonyl (MMT) is an excellent unleaded gas oline additive that can replace tetrae thyl lead. After reacting with carbon mon oxide, it can generate **solid cyclopentadienyl manganese tricarbonyl [(eta5-C5H5)Mn(CO)3] with stable chemical properties. 

Oil plants optimize the allocation of resources, which saves crude  oil. The use of MMT can reduce the crude  oil requirement by about 1-2%, depending on the concentration of MMT added. In the United States, it is estimated that 82,000 barrels/day of crude  oil will be saved if all gaso line is treated with MMT. It is estimated that more than 5 million tons of gaso line have been imported into MMT in China last year. If MMT is not used, but the same octane number is achieved by technological methods, 200,000 tons of crude  oil will be consumed.

1. 1.Gas oline anti-riot agent: Practice has proven that the anti-riot efficiency of MMT is about twice higher than that of general anti-riot agents. Since 1976, Canada, the United States and other countries have been using MMT as a gas oline anti-riot agent to increase the octane number.
2. 2.Gas oline standard increaser: MMT can increase the octane number of gas oline, thereby achieving the effect of increasing it.
3. 3.Unleaded gas oline antiknock agent: As an additive for unleaded gas oline, MMT can replace tetrae thyl lead, reduce the lead content in gas oline, and meet environmental protection requirements.
4. 4.Gas oline octane improver: MMT can improve the octane number of gas oline and make it more high-quality.
5. 5.Octane additive: MMT can increase the octane number of gas oline, thereby improving the quality of gas oline.
6. 6.Chemical Reagent: Bis(tetramethylcyclopentadienyl)manganese(II) is a chemical substance used as a chemical reagent.
7. 7.In short, 2-methylcyclopentadienyl manganese tricarbonyl, as an unleaded gas oline additive, has excellent anti-riot properties and the ability to increase the octane number of gas oline. It has broad application prospects in my country.
