Preparation methods · 1 item

PreparationCopper(I) acetate, CuC2H3O2, [598-54-9], MW 122.6, is produced by reducing an ammonia solution of copper(II) acetate. On acidification, white crystals of copper(I) acetate precipitate. The crystalline material is stable when exposed to dry air but decomposes on exposure to moisture in air. Ammonia solutions of copper(I) acetate are used to absorb olefins.
