Polymorphic transformations of edible vegetable fats / Polimorfne transformacije jestivih biljnih masnoća
(Tehnološki fakultet, Naučni institut za ratarstvo i povrtarstvo i DOO "Industrijsko bilje", Novi Sad, 2002)
Triglycerides are characterized by complex melting behaviour, as reflected by multiple melting temperatures. They can solidify in different crystal structures and this polymorphism can be defined as the ability to reveal ...
Adsorption and corrosion inhibitive properties of some organic molecules on iron electrode in sulfuric acid
(Elsevier, 2002)
Adsorption and corrosion inhibitive properties of three different organic molecules: 2-naphthalenesulfonic acid, 2,7-naphthalenedisulfonic acid and 2-naphthol-3,6-disulfonic acid are investigated on Armco-iron electrode ...
Composition and antibacterial activity of Achillea asplenifolia essential oil
(Allured Publ Corp, Carol Stream, 2002)
The oil of a wild growing population of Achillea asplenifolia Vent. was studied for yield, composition and antibacterial activity. The major components in the oil were beta-caryophyllene (17.6%), germacrene D (15.6%) and ...
Methanol electrooxidation on supported Pt and Pt-Ru catalysts in acid and alkaline solutions
(Elsevier, 2002)
The kinetics of methanol oxidation on supported 47.5 wt.% Pt and 54 wt.% PtRu (with nominal Pt:Ru ratios of 2:3) catalysts are measured in 0.5 M H2SO4 and 0.1 NaOH at 295 and 333 K using thin-film rotating disk electrode ...
The retention behaviour of some cholic acid derivatives on different adsorbents
(Research Inst Medicinal Plants, Budakalasz, 2002)
The thin-layer chromatographic behavior of cholic acid and fourteen of its synthetic derivatives has been studied in six reversed-phase and three normal-phase systems. Four significantly different adsorbents were used - ...
Photooxidation of n-heptanal in air: Norrish type I and II processes and quantum yield total pressure dependency
(Royal Society of Chemistry, 2002)
Dilute mixtures of n-heptanal in synthetic air (up to 100 ppm) were photolyzed with fluorescent UV lamps (275-380 nm) at 298 K. The main photooxidation products, identified and quantitatively analyzed by FTIR spectroscopy, ...
The diatomite: Type catalyst’s support / Nosač katalizatora tipa dijatomita
(Tehnološki fakultet, Naučni institut za ratarstvo i povrtarstvo i DOO "Industrijsko bilje", Novi Sad, 2002)
Hydrogenation of the animal fats and edible oils is a very important operation in the fats and oils industry. A catalyst usually used in industrial processes of the tallow and fat hydrogenation and in the vegetable oils ...
Partial hydrogenation of edible oils: Synthesis and verification of the nickel catalyst / Parcijalno hidrogenovanje jestivih ulja - sinteza i verifikacija katalizatora na bazi nikla
(Association of Chemical Engineers of Serbia, 2002)
Developed in the late 1800s as a butter substitute, margarine is made with vegetable oils. Margarine was created by a scientist from Provence (France) Hippolyte Mege-Mouries, in response to an offer by the Emperor Louis ...
Korelacija svojstava portland-cementnog klinkera i portland-cementa sa parametrima proizvodnje
(Materijali i konstrukcije, 2002)
Antimalarial peroxides: The first intramolecular 1,2,4,5-tetraoxane / Antimalarijski peroksidi - prvi intramolekulski 1,2,4,5-tetraoksan
(Serbian Chemical Society, 2002)
An intramolecular steroidal 1,2,4,5-tetraoxane has been synthesised in six steps starting from methyl3-oxo-7α,12α-diacetoxy-5β-cholan-24-oate. The synthesised 1,2,4,5-tetraoxane has moderate in vitro antimalarial activity ...
