An analogous series of dimethylalkyl compounds, consisting of four amines, an amide, and a phosphonate ester, inhibited motility and reproduction of the nematode Caenorhabditis elegans. Dimethylamines with straight-chain lengths of 12, 14, or 16 carbon atoms were equally active nematicides, causing greater than 80% population growth inhibition at a concentration of 25 ppm. The C12 straight-chai...

AIMS To assess the potential bactericidal activity of amine oxide (C10-C16-alkyldimethyl N-oxides) against Streptococcus mutans grown as planktonic suspension and as biofilm on hydroxyapatite discs, and its ability to control acidification of the media. METHODS Amine oxide bacteriostasis was investigated using the Bioscreen C Microbiological Growth Analyser, while a standard suspension test w...

removal of typical contaminants like aromatic amines (e.g. 1-naphthalen amine, diphenyl amine, aniline, 2 and 6-dimethyl pyridine) from water during one-stage process is a method to purify water wherein organic contaminants get extracted from water by bentonite. in this study the effects of ph, stirring time, stirring speed, bentonite mass and bentonite size (mesh) were investigated. also, the ...

the solubility of co2 in the primary, secondary, tertiary and sterically hindered amine aqueous solutions at various conditions was studied. in the present work, the modified kent-eisenberg (m-ke), the extended debye-hückel (e-dh) and the pitzer models were employed to study the solubility of co2 in amine aqueous solutions. two explicit equations are presented to evaluate the concentration of h...

biofiltration of triethylamine (tea) vapor used as a catalyst in casting operations was evaluated in this study. the unit consisted of a 6-l three-stage biofilter containing a mixture of compost and wood chips (40:60 v/v) as the filter medium. seed microbial population from municipal activated sludge was acclimated for a period of three weeks prior to the actual experimental runs. in the startu...

tetrahydropyranylation of alcohols and phenols, acetylation of aldehydes and n-boc protection of amines are efficiently catalyzed by melamine trisulfonic acid (mtsa). all reactions were performed at room temperature in good to high yields.

The imine podands tris[(2-nitrobenzylidene)aminoethyl]amine and tris[(2-nitrobenzylidene)aminopropyl]amine both stabilize copper(I), forming {tris[(2-nitrobenzylidene)aminoethyl]amine-kappa4N}copper(I) perchlorate acetonitrile disolvate, [Cu(C27H27N7O6)]ClO4.2CH3CN, (II), and {tris[(2-nitrobenzylidene)aminopropyl]amine-kappa4N}copper(I) perchlorate, [Cu(C30H33N7O6)]ClO4, (VI), respectively. The...
