use | mainly used as various metal derivatives, special binders, flame retardants, etc. For example, methyl cyclopentadienyl manganese tricarbonyl (MMT) prepared by MCPD is a gasoline antiknock agent, which has the characteristics of energy saving and pollution reduction; another example is used to prepare epoxy resin curing agent methyl naditic anhydride (MNA), due to the presence of methyl in its molecule, its chemical products have more superior properties and uses than cyclopentadiene in some properties. The product is mainly used to make epoxy resin curing agent methyl nadidicic anhydride (MNA) and gasoline antiknock agent methyl cyclopentadienyl manganese tricarbonyl (MMT) raw materials, but also used to make polyolefin catalysts, medicine, high-energy fuels, dye additives and other new products. |
