ActiveUS7258899B1Easy to handleMetallic state is rapidPretreated surfacesLiquid/solution decomposition chemical coatingAlloySolvent
A method for depositing metals, metal blends and alloys onto substrate surfaces, including microporous substrates utilizing a plasma operation undertaken at room temperature. In the process, a liquid solution of a monomer or comonomer precursor having a metallic component is utilized to wet the surface of the substrate, with the solvent portion thereafter being removed to leave the substrate surface coated with a dry deposit. The coated substrate is then introduced into a plasma reaction chamber with RF energy being applied across spaced electrodes to create a plasma glow along with the introduction of a plasma supporting gas. The substrate is exposed to the plasma glow for conversion of the precursor to dissociated form to create a deposit consisting essentially of the metallic component in elemental form as a cohesive film on the substrate surface. Preferred metals include such noble metals as platinum, gold and silver, as well as other metals. Preferred precursors include platinum hexafluoro-acetylacetonate, (trimethyl) methylcyclopentadienyl platinum, dimethyl(acetylacetonate) gold, and trimethyl phosphine (hexafluoroacetyl acetonate) silver.

In the prior art, a large amount of PM2.5 can be produced after the gasoline produced by using methyl tert-butyl ether (MTBE) and methylcyclopentadienyl manganese tricarbonyl (MMT) as the additive is burned so as to pollute the environment. According to the present invention, the problem in the prior art is solved, and the obtained cleaning gasoline is particularly suitable for the gasoline engine combustion.

The invention relates to a method of separating cyclopentadiene and methyl cyclopentadiene from a mixture with ingredients of dicyclopentadiene and dimethyl cyclopentadiene. The method is particularly suitable for purifying and separating the cyclopentadiene and methyl cyclopentadiene from ethylene byproduct C9 or crude cyclopentadiene. Ethylene byproduct C9 or crude dicyclopentadiene that contains dicyclopentadiene and dimethyl cyclopentadiene is put into a high-temperature cracking reactor that is arranged in a tower boiler of a rectifying tower 1; pyrolyzed mixture gas under high temperature runs upwards through the rectifying tower to lead distillate that contains the cyclopentadiene and the methyl cyclopentadiene to be separated at the top of the tower; the mixture distillate of the cyclopentadiene and methyl cyclopentadiene that is extracted at the top of the rectifying tower 1 enters a rectifying tower 2, and the cyclopentadiene is extracted from the top of the tower and the methyl cyclopentadiene is extracted from the bottom of the tower.
