Methylcyclopentadiene manganese tricarbonyl (MMT) (CAS: 12108-13-3)

Added quantitiy in gasoline

Chemical molecular formula: C6H7Mn(CO)3Chemical name: Methylcyclopentadiene manganese tricarbonyl

Molecular Weight: 218 

Existent state: Room temperature for liquid 

MMT-cyclopentadienyl manganese tricarbonyl & MMT—methylcyclopentadienyl manganese tricarbonyl have many advantages such as they can increase the gasoline octane number, reduce the auto tail gas discharge effectively, has high efficiency and low use-cost and so on. They have reached the international similar products level and have succeeded in filling the domestic blank for producing unleaded gasoline antidetonator. 

Hydrocarbons’ receptivity towards MMT:
· Paraffins>Olefins>Aromatics
· Low octane number fuel oil>High octane number fuel oil
· Research method>Motor method
· The antiknocking efficiency is twice as tetraethyl lead 
· The gasoline ON improvement effect of adding 18mg/l MMT is equivalent to the ON improvement effect of blending MTBE of 8%-10% with gasoline.

Performances & Characteristics:
(1) Can improve gasoline’s octane number
(2) Can improve vehicle dynamic quality and reduce oil consumption
(3) Favorable compatibleness with MTBE, ethanol and so on oxygen bearing constituents
(4) Reduce the pollutant discharges in the automobile end gas
(5) Has the improvement function to the vehicle exhaust catalytic converter
(6) Improve oil refining operation
● Reduce the reforming plant’s operational severity level
● Reduce the aromatic content in the gasoline
● Reduce the olefins content in the gasoline
● Reduce the crude oil’s demand quantity

(7) Strengthen oil product blending’s flexibility

Packaging:
200L galvanized iron drum, 180kg net weight/drum; Or can adopt other packing forms according to customer’s actual demand.

Storage:
The use of 103 steel cans weighing 10 -12t; 200L galvanized iron weighing 200kg; customers may also need other practical packaging.

Methylcyclopentadienyl manganese tricarbonyl (MMT or MCMT) is anorganomanganese compound with the formula (CH3C5H4)Mn(CO)3. Marketed as a supplement to the gasoline additive tetraethyllead to increase a fuel’s octane rating, MMT was later used in unleaded gasoline. Following the implementation of the Clean Air Act (United States) (CAA) in 1970, MMT continued to be used alongside TEL in the US during the phase-out of leaded gasoline (prior to TEL being finally banned from US gasoline in 1995) and was also used in unleaded gasoline until 1977. Ethyl Corporation obtained a waiver from EPA in 1995. The waiver allows the use of MMT in US unleaded gasoline (not including reformulated gasoline) at a treat rate equivalent to 8.3 mg Mn/l.

MMT has been used in Canadian gasoline since 1976 at a concentration up to 18 mg Mn/l (though the importation and interprovincial trade of gasoline containing MMT was restricted briefly during the period 1997-1998) and was introduced intoAustralia in 2000. It is sold under the tradename HiTEC® 3000. It was also marketed as Ecotane by T2 Labs.
