Dynamical mechanical analysis of photocrosslinked hyperbranched urethane acrylates
(Srpsko hemijsko društvo, Beograd, 2004)
A series of acrylate functionalized samples based on hyperbranched hydroxy-terminated polyesters with different molecular weights and different degrees of acrylation were synthesized. The obtained urethane acrylates were ...
The influence of the solvent on organic reactivity. Part II. Hydroxylic solvent effects on the reaction rates of diazodiphenylmethane with 2-(2-substituted cyclohex-1-enyl)acetic and 2-(2-substituted phenyl)acetic acid / Uticaj hidroksilnih rastvarača na brzinu reakcije diazodifenilmetana Sa 2-(2-supstituisanim cikloheks-1-enil)sirćetnim i 2-(2-supstituisanim fenil)sirćetnim kiselinama
(Serbian Chemical Society, Belgrade, 2004)
The rate constants for the reaction of diazodiphenylmethane with 2-(2-substituted cyclohex-1-enyl)acetic acids and 2-(2-substituted phenyl)acetic acids, previously determined in seven hydroxylic solvents, were correlated ...
Temperature dependence of the Kovats retention indices for alkyl 1, 3-diketones on a DB-5 capillary column / Temperaturna zavisnost kovačevih retencionih indeksa 1,3-diketonan a DB-5 kapilarnoj koloni
(Serbian Chemical Society, Belgrade, 2004)
A series of alkyl 1,3-diketones were used to study the temperature dependence of the Kovats retention indices in the temperature range 130–190 ºC (403–463 K). The temperature dependence is described by the empirical equation ...
Alkylation of N-substituted-2-phenylacetamides / Alkilovanje n-supstituisanih 2-fenilacetamida
(Serbian Chemical Society, Belgrade, 2004)
Various N-substituted phenylacetamides were alkylated using different alkylating agents under neutral and basic conditions. Reactions were performed at different reaction temperatures and in various solvents. Also, a number ...
The structure directing role of 1,3-diaminopropane in the hydrothermal synthesis of iron(III) phosphate
(Srpsko hemijsko društvo, Beograd, 2004)
13-Diaminopropane (DAP) was used as a structure-directing agent for the hydrothermal synthesis of an organically templated iron phosphate. During crystallization at 180 degreesC, iron phosphate (FePO-DAP) with a layered ...
The effect of the particle shape and structure on the flowability of electrolytic copper powder, III: A model of the surface of a representative particle of flowing copper powder electrodeposited by reversing current / Uticaj oblika I strukture čestica na tečljivost elektrolitičkog bakarnog praha III - model površine reprezentativne čestice tečljivog bakarnog praha dobijenog elektohemijskim taloženjem reversnom strujom
(Serbian Chemical Society, 2004)
The structure of the surface of copper powder particles is discussed and correlated with the lowest apparent density at which copper powder can still flow. It is shown that such structures can be easily obtained in the ...
MS analysis of biindenylidenes / MS analiza biindenilidena
(Serbian Chemical Society, Belgrade, 2004)
Biindenylidene isomers are components of pyrolysis oils. The mass spectra were recorded and the fragmentation of the following biindenylidene isomers (E)-2,3,2’,3’-tetrahydro- [1,1’]biindenylidene (Z)-2,3,2’,3’-tetrahydr ...
The effect of the particle shape and structure on the flowability of electrolytic copper powder. IV. The internal structure of the powder particles
(Journal of the Serbian Chemical Society, 2004)
The structure of powder particles was analysed by considering their cross sections. It was shown that the structure of powder particles of nonsieved flowing powders is sufficiently dense to produce a continuous surface, ...
The examination of parameters for lactic acid fermentation and nutritive value of fermented juice of beetroot, carrot and brewer’s yeast autolysate / Određivanje parametara mlečno-kisele fermentacije i nutritivne vrednosti fermentisanog soka cvekle, mrkve i autolizata pivskog kvasca
(Serbian Chemical Society, Belgrade, 2004)
The conditions for lactic acid fermentation based on a mixture of beetoot juice (Beta vulgaris L) and carrot juice (Daucus carota L) and different content of brewer’s yeast autolysate with Lactobacillus plantarum A112 and ...
