Methylcyclopentadienyl manganese tricarbonyl diluent and preparation method thereof

Abstract

The invention discloses a gasoline additive, in particular methylcyclopentadienyl manganese tricarbonyl diluent. The diluent is characterized by comprising the following materials in percentage by weight: 60 to 65 percent of methylcyclopentadienyl manganese tricarbonyl, 15 to 23 percent of solvent, 0.5 to 5 percent of antioxidant, 1 to 10 percent of light stabilizer, 1 to 5 percent of dispersing agent and 0.5 to 2 percent of metallic corrosion inhibitor, wherein the solvent is at least one of toluene and xylene; the antioxidant is 4,4'-thiobi(2-methyl-6-t-butyl phenol) or 1,1,3-tri(2-methyl-4-hydroxy-5-t-butyl phenyl) butane; and the light stabilizer is at least one of bi(1,2,2,6,6-pentamethyl-4-piperidine) sebacate and 1-methyl-8-(1,2,2,6,6-pentamethyl-4-piperidine). The methylcyclopentadienyl manganese tricarbonyl diluent has the advantages of making resistance to oxidation and light stability of the product greatly improved, and greatly improving storage, transportation and use conditions of the product due to great reduction of the solidifying point of the diluent.

Description

technical field [0001] The invention relates to a gasoline additive, in particular to a gasoline antiknock agent and a preparation method thereof. Background technique [0002] As we all know, due to the toxicity of tetraethyl lead, it has caused serious pollution to the environment and threatened human health. Many developed countries in the world have formulated various policies and regulations to protect the environment and realize unleaded gasoline. Methylcyclopentadiene manganese tricarbonyl (MMT) has been used instead of tetraethyl lead as gasoline antiknock additive, and the effect is very good. [0003] Methylcyclopentadiene manganese tricarbonyl is an organometallic liquid compound, liquid at room temperature, not easy to crystallize, insoluble in water, has good chemical compatibility with oil, and does not decompose in air and dark environments. It can effectively improve gasoline quality, increase gasoline octane number, high anti-knock efficiency and small amou...

AI Technical Summary

Problems solved by technology

[0004] Methylcyclopentadiene manganese tricarbonyl (MMT) is liquid at normal temperature, but because it is easily oxidized, it must be protected by an inert gas. It is under protection, and its freezing point is high, which brings a lot of inconvenience to the storage, transportation and use of the product
