  2. Copper pesticide - Wikipedia

    en.wikipedia.org/wiki/Copper_pesticide

    Copper pesticide is applied as a contact protective foliar spray, so it remains deposited on leaf surfaces. A small concentration of copper ions may be taken up by plants as essential nutrients. Copper foliar sprays are also applied to correct plant copper deficiency. [8] Excess absorbed copper ions can kill sensitive cells in copper sensitive ...

  3. Copper naphthenate - Wikipedia

    en.wikipedia.org/wiki/Copper_naphthenate

    Copper naphthenate is classified by EPA as a general use (i.e., a non-restricted use) pesticide by virtue of its relatively benign toxicity profile. [5] Copper naphthenate is the only non-restricted use wood preservative in widespread use for "heavy duty" commodities such as utility poles, railroad crossties and timbers, pilings and fence posts.

  4. Alkaline copper quaternary - Wikipedia

    en.wikipedia.org/wiki/Alkaline_copper_quaternary

    Alkaline copper quaternary, usually abbreviated ACQ, is a type of water-based wood preservative product containing a soluble copper(II) complex and quaternary ammonium alkyl- or aryl-substituted compounds ("quats"). Thus the product was originally called ammoniacal copper/quaternary ammonium. [1] [2]

  5. Dicopper chloride trihydroxide - Wikipedia

    en.wikipedia.org/wiki/Dicopper_chloride_trihydroxide

    Large scale industrial production of basic copper chloride was devoted to making either a fungicide for crop protection or an intermediate in the manufacture of other copper compounds. [6] In neither of those applications was the polymorphic nature of the compound, or the size of individual particles of particular importance, so the ...

  6. Copper (I) chloride - Wikipedia

    en.wikipedia.org/wiki/Copper(I)_chloride

    The main use of copper(I) chloride is as a precursor to the fungicide copper oxychloride. For this purpose aqueous copper(I) chloride is generated by comproportionation and then air-oxidized: [12] Cu + CuCl 2 → 2 CuCl 4 CuCl + O 2 + 2 H 2 O → Cu 3 Cl 2 (OH) 4 + CuCl 2. Copper(I) chloride catalyzes a variety of organic reactions, as

  7. Copper (II) chloride - Wikipedia

    en.wikipedia.org/wiki/Copper(II)_chloride

    Copper(II) chloride is used as a catalyst in a variety of processes that produce chlorine by oxychlorination. The Deacon process takes place at about 400 to 450 °C in the presence of a copper chloride: [8] 4 HCl + O 2 → 2 Cl 2 + 2 H 2 O. Copper(II) chloride catalyzes the chlorination in the production of vinyl chloride and dichloromethane. [8]
