O.N. of gasoline & CMTCMT has the merits of low freeing point,high boiling point,low volatilization, etc.       CMT dissolves in gasoline but not water at room temperature. It enhances the efficiency of explosive resistance of the gasoline without increasing its toxicity. Its level of O.N. is twice as high as that of tetraethyl lead by metal weight. With the wider application of unleaded gasoline,CMT will be a better alternative to tetraethyl lead.Sensibilities of hydrocarbon towards CMT: ·paraffins>olefins>aromatics ·   lower O.N. fuels>higher O.N. fuels ·   RON>MON(research octane number>motor octane number) ·The explosive resistant efficiency of CMT is about twice as that of tetraethyl lead·   The O.N. boosting result of adding 18mg/l(manganese concentration) CMT to gasoline is almost the same as blending MTBE at 8%~10%(volume) with gasoline.Packaging &StorageLiquid CMT20 is packed in metal plating pail (175kg/pail),or in special storage tanks (10 or 5). Crystal CMT is packed in pail (25kg/pail) CMT20 can be stored under ordinary temperature, without exposure to the sun or rain,far away from fire. Be sure to close the container when it is not being used.CMT is sensitive to light,a brown bottle or metal pail should be used to obtain samples of gasoline added with CMT for testing. The sample should be kept in an opaque container and stored in a dark and cool place.Usage of CMTCMT20 can be addded into gasoline in proper proportion. Dosage of CMT

What can we profit from CMT?    Add one ten-thousandth of CMT (volume) to the gasoline, with manganese concentration of 18mg Mn/L, the O.N. level of gasoline can be boosted by 2 to 3 units, The O.N. boosting result of adding 18mg Mn/L(manganese content) CMT to gasoline is almost the same as blending MTBE at 10%(volume) with gasoline, but the cost of using CMT is 50% less than that of using MTBE.
