Antioxidant properties of some 5-ethoxycarbonyl-substituted 3,4-dihydropyrimidin-2(1H)-ones (-thiones) and their derivatives

Inhibiting properties of some synthesized 5-ethoxycarbonyl-substituted 3,4-dihydropyrimidin-2(1H)-ones (-thiones) and their derivatives in model reactions were studied.

Synthesis of N,N′-bis(alkyloxymethyl)piperazines and examination of their antimicrobial properties

Three-component condensation of piperazine with formaldehyde and aliphatic alcohols was employed for elucidating the possibility to synthesize N,N′-bis(alkyloxymethyl)piperazines. The structure of the resulting compounds was identified by 1H NMR spectroscopy. The antimicrobial properties of these compounds were examined with respect to microorganisms that infect cooling lubricants and lubricant oils.

Synthesis and antimicrobial properties of 3-(β-hydroxyethyl)-1,3-oxazolidins

The possibility of synthesis of 3-(β-hydroxyethyl)-1,3-oxazolidin and its substituted derivatives at position 2 by the condensation-heterocyclization of diethanolamine with certain aldehydes and ketones was examined. The structure of the compounds was identifi ed by NMR spectroscopy. We investigated antimicrobial properties of the synthesized compounds against microorganisms that affect the lube oil M-11 and found a dependence of the antimicrobial properties on the nature of the substituent at position 2 of oxazolidin heterocycle.

Cyclic thioureas as cumene oxidation inhibitors

Hexahydro-1,3,5-triazine-4-thiones were synthesized by ternary condensation of thiourea with various aldehydes and amines. The products were characterized by IR and NMR spectroscopy, and their inhibiting effect on cumene oxidation was examined.

Reaction of α-chloro-β-oxobutanal with indole derivatives

The reactions of 2-methylindole and 2-methylindol-3-yldiphenylphosphine with α-chloro-β-oxobutanal was studied.

Synthesis and antioxidant activity of 1-amino-4-phenyl-2-butanethiols

Abstract1-Amino-4-phenyl-2-butanethiols were synthesized and characterized and their antioxidant activity in auto-oxidation of cumene and in their reaction with cumyl peroxide radicals and cumyl hydroperoxide was studied.

Antioxidant properties of sulfides derived from 2-propylphenol and of their aminomethyl derivatives

Antioxidant properties of sulfides derived from 2-propylphenol and of their aminomethyl derivatives were studied in a model reaction of cumene oxidation. The kinetic parameters of the reactions of these compounds with cumylperoxy radicals and cumyl hydroperoxide were determined.

Synthesis and Antioxidative Activity of S-Substituted 2-Mercapto-1,4-dihydroxybenzenes

S-Substituted 2-mercapto-1,4-dihydroxybenzenes were prepared, and their antioxidative activity in autooxidation of cumene and in the reactions with cumylperoxy radicals and cumyl hydroperoxide was studied.

Mechanism of the Antioxidative Effect of Bis(4-hydroxy-3,5-di-tert-butylphenyl) Sulfide and Polysulfides in Cumene Oxidation

Bis(4-hydroxy-3,5-di-tert-butylphenyl) sulfide and polysulfides were prepared, and their inhibiting power was studied in relation to the number of sulfur atoms.

Binary cooligomers of 2-propenylphenol with 1-heptene and 1-decene as antimicrobial additives for lubricating oil I-12A

Binary cooligomers of C7 and C10 α-olefins with 2-propenylphenol were synthesized in the presence of a complex catalyst based on aluminum chloride, toluene, and ethyl chloride (1:3.0:0.6 mol). Tests of the cooligomers as antimicrobial additives to I-12A oil showed that, in concentrations of 0.25 and 0.5%, they inhibit fungal growth, being superior to 8-hydroxyquinoline (reference) in the efficiency of action.
