The invention provides a neo-decyl diacyl oxime extracting agent and a preparation method and application thereof, and belongs to the technical field of hydrometallurgy extractants, the preparation method comprises the following steps: reacting neodecanoyl chloride in the presence of a metal catalyst to generate neo-decyl diacyl, and separating out the neo-decyl diacyl to obtain the neo-decyl diacyl oxime. And further reacting with hydroxylamine under an alkaline condition to generate neodecyl dioxime or a neodecyl dioxime extracting agent. The prepared neodecyl diacyl oxime extracting agent can be applied to recovery of various metals such as copper, cobalt, nickel, manganese, rare earth and the like, an aluminum trichloride catalyst used in a traditional ketoxime synthesis process is replaced by the ferromanganese alloy, the use amount of the catalyst is reduced, the production cost is reduced, and meanwhile, the discharge of metal-containing wastewater is reduced. The neo-decyl diacyl oxime extraction agen
