Patent ID: 8828352

Claim:
A process for preparation of silver oxide comprising: preparing a precursor solution including a silver complex compound obtained by reacting a silver compound represented by Formula 1 below with one or more selected from an ammonium carbamate-based compound, an ammonium carbonate-based compound or an ammonium bicarbonate-based compound represented by Formulas 2, 3 or 4 below in the presence of a solvent; and preparing silver oxide by reacting the precursor solution including the silver complex compound with an oxidant, wherein the oxidant is at least one selected from the group consisting of an oxidative gas, a peroxide, a peroxy acid, an oxidative inorganic acid, an oxidative metal compound, and an oxidative nonmetal compound; Ag n X {Formula 1} in the Formula 1, n is an integer from 1 to 4 and X is a substituent selected from the group consisting of oxygen, sulfur, halogen, cyano, cyanate, carbonate, nitrate, nitrite, sulfate, phosphate, thiocyanate, chlorate, perchlorate, tetrafluoroborate, acetylacetonate, carboxylate and derivatives thereof, in the Formulas 2 to 4, R 1 , R 2 , R 3 , R 4 , R 5 and R 6 is hydrogen, aliphatic or cycloaliphatic (C1-C30) alkyl group, (C6-C20) aryl group, (C6-C20) aryloxy group, (C6-C20) aryl (C1-C30) alkyl group, tri(C1-C30) alkylsilyl group, tri(C1-C30) alkoxy silyl group, tri(C6-C20) arylsilyl group, allyl group, or 3-membered to 7-membered heterocyclic compound group, polymer compound group, hydroxyl group, (C1-C30) alkoxy group, (C1-C30) alkylamino group, independently from each other, or R 1 and R 2 or R 4 and R 5 may be bonded independently from each other by (C2-C6) alkylene to form a ring, the alkyl group or aryl group of R 1 , R 2 , R 3 , R 4 , R 5 and R 6 may further be substituted by aliphatic or cycloaliphatic (C1-C30) alkyl, (C1-C30) alkoxy, cyano, hydroxy, amino, (C6-C20) aryl, tri (C1-C30) alkylsilyl, tri (C1-C30) alkoxysilyl, tri (C6-C20) aryl silyl, allyl or carboxylic acid.
