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.
Copper Naphthenate can be applied by brush, dip, or pressure treatment. The University of Hawaii has found that copper naphthenate in wood at loadings of 1.5 lb/cu ft (24 kg/m 3) is resistant to Formosan termite attack. On February 19, 1981, the Federal Register outlined the EPA's position regarding the health risks associated with various wood ...
An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.
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]
Illustrative is the use of cobalt naphthenate for the oxidation of tetrahydronaphthalene to the hydroperoxide. [ 16 ] The complex mixture and hydrophobic nature of naphthenic acid allows metal naphthenates to be highly soluble in organic media such as petroleum-based hydrocarbons, oftentimes much more so than single isomer carboxylates such as ...
A well-defined compound that exhibits many of the properties of cobalt naphthenate is the cobalt(II) complex of 2-ethylhexanoic acid. Often in technical literature, naphthenates are described as salts, but they are probably also non-ionic coordination complexes with structures similar to basic zinc acetate .
