Uses and applications
What the substance is used for, by industry and function
In manufacture of rayon, battery electrodes, other copper salts, as mordant in dyeing, as pigment, in fungicides, insecticides, as feed additive, in treating and staining paper, in prepn of Schweitzer's reagent, in catalysts.
Used as an active precursor in the production of copper(II) compounds. Ammonia-processed copper(II) hydroxide is used in the production of copper(II) naphthenate, copper(II) 2-ethylhexanoate, and copper soaps. Ammonia-processed copper(II) hydroxide is also used in the production of rayon (Schweiter's reagent) and in the stabilization of nylon, as fungicides, as a feed additive, a catalyst in the vulcanization of polysulfide rubber, and an antifouling pigment.
Used as fungicide against bacterial soft spot (Erwinia) on lettuce (foliar treatment), against bacterial spot (Xanthomonas pruni) on peaches (dormant and foliar treatment), against leaf and stem blight and storage rot on cranberries (dormant application) and against cranberry hard rot (cottonball, Monilinia oxycocci) on cranberries (delayed dormant application). (Kocide 101).
