BIOCIDAL COMPOSITION AND METHOD OF INHIBITING GROWTH OF MICROORGANISMS IN MEDIA Russian patent published in 1995 - IPC

FIELD: biotechnology. SUBSTANCE: claimed are biocidal compositions based on heterocyclic thioderivatives of the general formula: wherein or ≡ CR₂, or ≡ CR₂, or =C=NR₂; D=NR₂ or S; R H, Ac or COOR′; R is-Alk having 1 to 5 carbon atoms, R₃ - H, Alk having 1 to 5 carbon atoms, phenyl, chlorophenyl or a 5 or 6-member hydrocarbon cycle attached to one or two carbon atoms of the heterocycle, the ratio of the components being as follows (wt%): 0.00002-5.0 and a diluent, the balance. Compositions are added to various industrial liquids or factory production waste for suppressing the growth of microorganisms; they are used for conserving paints, glues, leather and wood. The claimed compositions are stable and can by easily handled in conserving media. EFFECT: improved properties of the biocidal composition. 6 cl, 1 tbl
