BIOCIDAL ACTIVITY OF AMINOMETHYL DERIVATIVES OF 2-MERCAPTOBENZOXAZOLE

The biocidal activity of the aminomethyl derivatives 2-mercaptobenzoxazole synthesized by us and being interest as potential antimicrobial additives to petroleum products cutting fluids, was studied. aminomethylation reaction proceeded with participation methylene-bis-amines. As a result, appropriate N-substituted benzoxazolin-2-thiones were obtained. Their structure proved NMR 1H. Due poor solubility compounds in products, their salts naphthenic acid obtained for microbiological testing. results tests lubricating oil M-8 show that exhibit fungicidal properties are higher than bactericidal ones. used test its pure form composition is not biostable affected microorganisms. N-piperidinomethylbenzoxazolin-2-thione coolant be biocide, study an aqueous solution this compound showed high absence effectiveness against mold fungi.
