摘要： The present disclosure relates to a method for manufacturing core-shell particles using carbon monoxide, and more particularly, to a method for manufacturing core-shell particles, the method of which a simple and fast one-pot reaction enables particle manufacturing to reduce process costs, facilitate scale-up, change various types of core and shell metals, and form a multi-layered shell by including the steps of adsorbing carbon monoxide on a transition metal for a core, and reacting carbon monoxide adsorbed on the surface of the transition metal for the core, a metal precursor for a shell, and a solvent to form particles with a core-shell structure having a reduced metal shell layer formed on a transition metal core.

摘要： A process can be used for producing methacrylic acid or a methacrylic acid ester. The process involves producing acrolein, reacting the produced acrolein with hydrogen to produce propanal, reacting the propanal with formaldehyde to produce methacrolein, and oxidizing the methacrolein in the presence of an oxygen containing gas and optionally an alcohol, to obtain methacrylic acid or methacrylic acid ester.
