ZINC OR COPPER (II) SALT AND USE THEREOF AS BIOCIDE Russian patent published in 2013 - IPC C09D5/14 C07C69/78 

FIELD: chemistry.

SUBSTANCE: invention relates to novel chemical compounds - zinc and copper salts with organic acids, which can be used as biocides intended, for example, for use in polymer materials, disinfectant and antiseptic compositions, treating wood, paper, building structures and other materials in order to prevent spoiling under the effect of biological objects (microorganisms, fungi, algae), making different articles with biocidal properties, etc. Zinc or copper (II) salt of general formula CH₂=C(R¹)COO-M-OCOC₆H₃R²R³, where M denotes Zn or Cu, R¹ is selected from a group comprising hydrogen and methyl, R² is selected from a group comprising hydrogen and OH, R³ is selected from a group comprising alkyl and a SO₂OH group. The invention also relates to use as a biocide of a zinc or copper (II) salt of general formula CH₂=C(R¹)COO-M-OCOC₆H₃R²R⁴, where M denotes Zn or Cu, R¹ is selected from a group comprising hydrogen and methyl, R² is selected from a group comprising hydrogen and OH, R⁴ is selected from a group comprising alkyl and a SO₂OH group.

EFFECT: obtained zinc or copper (II) salts have high biocidal activity and a wide range of activity on biological objects.
