Product name: NMT
Chemical name: Nkcyclopentadienyl manganese tricarbonyl(CMT); methyl cyclopentadienyl manganese tricarbonyl(MMT)
Chemical molecular formula :C₅H₅Mn(CO)₃       C₆H₇Mn(CO)₃

Mechanism of action
Similar to the tetraethyl lead, that is, the product can be decomposed into small particles of active manganese oxides under combustion conditions, owing to its surface action, these small particles effectively destroy those superoxides that already existed in the engine, reduces the concentration of the superoxides during the preflame reaction, meanwhile cuts a part of chain reactions selectively, thus hinder the autogenous ignition, slowed down the energy release speed, thereby improve the fuel's antidetonating quality.

Performances & Characteristics
(1) Increase the ON of gasoline
Add one ten-thousandth of NMT/MMT to the gasoline,with manganese content less than 18mg/l,the ON of gasoline can be increased to 2 to 3 units.
(2) Increase vehicle dynamic quality,decrease its oil consumption
Through the evaluation of engine bed by the Motor Transport Industry Energy Utilization Monitor Center of Ministry of Communications,we drew out the conclusion that: unleaded 90# gasoline with NMT/MMT additives can increase engine dynamic behavior and decrease its oil consumption compared with 90# gasoline without NMT/MMT additives
(3) Favorable soluble abilities with MTBE and ethanol and so on oxygen bearing constituents
At the aspect of improving the octane number, NMT can be used well together with MTBE and ethanol, this character provides a convenient way for producing high grade gasoline. It not only can increase the ON, but also can avoid decreasing the vehicle dynamic quality by using too much MTBE,then help to meet the National Standards of "less than 2.7% oxygen content"
(4) Reduce automobile exhaust pollutant discharges
The CO in the engine tail gas of the unleaded 90# gasoline with NMT/MMT additives can drop to 17.7% and the HC can drop to 18.2% compared with 90# gasoline without NMT/MMT additives.
(5) Has the improvement function to the automobile emission catalytic converter
The phosphorus is the recognized catalyst machine toxin, when the NMT is burning, can eliminate the phosphorus and reduce the deposit on the catalyst, therefore uses NMT/MMT fuel can lengthen the catalyst life, make the catalyst to maintain the high conversion rate, thus effectively transform the noxious gas, reduce the pollutant discharge.
(6) Improve oil refining operation
● Reduce the reforming plant operation's severity level
● Reduce the aromatic content in the gasoline
● Reduce the olefin content in the gasoline
● Reduce the crude oil's required volume
(7) Strengthen product blending's flexibility
(8) Has better light stability
Under normal temperature, the NMT is yellow crystal, has good light stability, this brings enormously convenience to the the storage and transportation. When use this product, should compound into the solution, enhance its stability by using the unique formula.

Packaging
For liquid product: packed in 200L galvanized iron drum, net weight 170Kg /drum; For the solid products: packed in 60L thick wall plastic drum, net weight 50kg ; or packed in 20L iron drum, net weight 17Kg /drum; or adopt other packing forms according to customer's actual demand.

Storage
Stores up in cool, dry, well ventilated place, far away the fire hazard, if does not use should close the vessel tightly.
For those gasoline sample and file sample containing NMT/MMT should use the chocolate brown bottle.
