Patent ID: 8491866

Claim:
A process for preparation of silver oxide comprising: preparing a precursor solution including a dispersing agent and 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 Formula 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; 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) ar (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, which includes or does not include hetero atom, 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) alkioxy, cyano, hydroxy, amino, (C6-C20) aryl, tri (C1-C30) alkylsilyl, tri (C1-C30) alkoxysilyl, tri (C6-C20) aryl silyl, allyl or carboxylic acid.
