Tridecyl acetate was administered to male and female Sprague-Dawley rats by oral gavage, 5 days per week for 13 weeks (90 days). Treated rats received daily doses of 0.1, 0.5, or 1.0 g/kg/day and control rats received distilled water at a dose of 1.0 g/kg/day. After 45 days an interim terminatio...

Tetradecanoic acid was decarboxylated by means of lead(IV) acetate (LTA) under thermal (81 °C) and photolytic (r.t.) conditions in benzene solution. The mixture of products, obtained in thermal reaction, consists of esters (acetoxyalkanes and carboxylates), tridecenes, tridecane and phenyltride...

Three surfactant-assisted shotgun methods using acid labile surfactants, sodium-3-[(2-methyl-2-undecyl-1,3-dioxolan-4-yl)-methoxyl]-1-propanesulfonate (RapiGest) and 3-[3-(1,1-bisalkyloxyethyl)pyridin-1-yl]propane-1-sulfonate (PPS), and sodium dodecyl sulfate (SDS) were investigated for their ap...

The CMC of sodium n-octyl, n-nonyl, n-decyl, n-undecyl and n-dodecyl sulphates in glycine buffer solutions at pH 3.2 were precisely determined at 15, 20, 25, 30 and 35°C by an electrical conductivity method. For each of the surfactant—solvent systems investigated the values of the CMC in each ...

Novel, anionic surface-active monomers, sodium di(10-undecenyl)sulphosuccinate (DUSS) and sodium n-undecyl 10-undecenylsulphosuccinate (MUSS) were prepared. The monomers were soluble in both water and apolar organic solvents on heating. DUSS and MUSS in water exhibited Kraft points at about 39°...

The binding of sodium n-undecyl sulfate with bovine insulin was studied at pH 3.2 and 10 by equilibrium dialysis at 25°C. The binding data have been used to determine the Gibbs energies of interaction using the theoretical model of the Wyman binding potential. The curves of Gibbs energies as a ...

The energy of combustion of perfluoro-2,7-dimethyloctane has been measured in a rotating bomb calorimeter, ΔcU0(1) = −3198.2 ± 8.6 kJ mol−1. The enthalpy of formation, ΔfH0(1) has been obtained by combination of the experimental data with the accepted values for the enthalpies of formation of...

High molecular weight iso-paraffinic molecules are found in conventional petroleum, Fischer–Tropsch (FT), and other alternative hydrocarbon fuels, yet fundamental combustion studies on this class of compounds are lacking. In the present work, ignition delay time measurements in 2,7-dimethylocta...

The unseeded emulsion polymerization of styrene with n-nonyl mercaptan (nNM) as chain transfer agent (CTA) was investigated, with the aim of producing a PS latex of a low molecular weight polydispersity at high conversion and in short reaction times. To this effect, starved and minimum time semi...

The dye 10-N-nonyl acridine orange (NAO) is used to label cardiolipin domains in mitochondria and bacteria. The present work represents the first study on the binding of NAO with archaebacterial lipid membranes. By combining absorption and fluorescence spectroscopy with fluorescence microscopy s...

In this study, our purpose is to analyze combined effects of nonyl phenol (NP) and di-n-butyl phthalate (DBP) for rat testicular Sertoli cell toxicity in vitro. Sertoli cells were isolated, purified, cultured, and identified with FSHR fluorescence staining. Then the purified Sertoli cells were t...

Enzymatic browning and bacterial putrefaction are mainly responsible for quality losses of Chinese Olive (Canarium album) postharvest and lead to very short shelf life on average. Screening anti-browning and anti-bacterial agents is important for preservation of Chinese Olive. Caffeic acid N-non...

In this work the effects of solvent polarity and conformation changing on the electronic characteristics of poly(di-n-hexylsilane) incorporated in the nanoporous materials are calculated. The dependence of energy levels of electronic-excited states of investigated compounds is analyzed as a func...

This paper describes the preparation of oxidized hyaluronan crosslinked gelatin microspheres for drug delivery. Microspheres were prepared by a modified water-in-oil-emulsion crosslinking method, where three-dimensional crosslinked hydrogel microspheres formed in the absence of any extraneous cr...

For the development of 62Cu labeled fatty acid analogs, two fatty acid analogs, containing dithiosemicarbazone (DTS) molecule as the 62Cu coordinating site, were designed and synthesized: a fatty acid analog containing DTS molecule at the omega-position, (a) the 12,13-dioxotetradecanoic acid di(...

The Amberlite XAD resins coated with dithiosemicarbazones were prepared and their collection behavior of metal ions from aqueous solution was investigated. Among the resins used, the reagent-loaded Amberlite XAD-7 was found to be superior for the collection of metal ions to other reagent-loaded ...

The formation of complexes at pH 4.7 of the Hg(II) with five monothiosemicarbazone and two dithiosemicarbazone has been studied. The mercury(II) reacts with monothiosemicarbazones of salicylaldehyde (λmax = 363 nm, E = 1.69 × 104liters · mol−1cm−1), pi-colinadehyde (λmax = 363 nm, E = 2.38 ×...
