Benzylation of N-benzyl-2-phenylacetamide
(Serbian Chemical Society, Belgrade, 1999)
N-Benzyl-2-phenylacetamide was used as a model for the study of the alkylation of N-substituted 2-phenylacetamides with benzyl chloride in the presence of powdered KOH. The reactions were carried out in the presence and ...
Phase-transfer ethylation of N-substituted phenylacetamides
(Pleiades Publishing, Ltd., 1998)
A CoAPO-34 derived from a triclinic precursor prepared in the presence of HF
(Elsevier Science Inc., 1997)
The fluoride route of synthesis of AIPO,-34 is also successful in the preparation of its cobalt modified product (CoAPO-34). The triclinic precursor of CoAPO-34 has been synthesized in the presence of HF and piperidine. ...
Retention behavior of some amides in reversed- and normal-phase thin-layer chromatography
(Springer Heidelberg, Heidelberg, 1992)
The retention behavior and separation ability of reversed- and normal-phase TLC with, polar and nonpolar mobile phases, has been studied by measuring the retentions of a series of amides. The retention behavior and separation ...
The influence of permanent dipole moments on second harmonic generation in asymmetric semiconductor quantum wells
(Elsevier, Amsterdam, 1997)
The influence of permanent dipole moments on intersubband double resonance second harmonic generation in asymmetric quantum wells is analyzed. It is found that in realistic QWs matched for 10.6 mu m pump the permanent ...
Benzylation of N-phenyl-2-phenylacetamide
(Natl Inst Science Communication, New Delhi, 1997)
Benzylation of N-phenyl-2-phenylacetamide with benzyl chloride in the presence of powdered KOH has been carried out to find out the possible reaction products as well as to ascertain optimal reaction conditions for the ...
Phase-transfer allylation of N-ethylphenylacetamide
(Russian Journal of Organic Chemistry, 1998)
CoAPO-21, a cobalt-doped aluminophosphate related to AlPO4-21

On the possibility of the preparation open framework manganese phosphate
(Elsevier Inc., 1996)
Manganese(ll)/phosphate/organic template hydrothermal reactions were investigated with the aim of preparing novel crystalline porous materials. Ethylenediamine, isopropylamine, and piperidine were explored as organics that ...
UTICAJ EKSPERIMENTALNIH USLOVA NA ODREĐIVANJE JEDNOCIKLIČNIH KARAKTERISTIKA PREĐA PRI ISTEZANJU / INFLUENCE OF EXPERIMENTAL CONDITIONS ON DETERMINATION OF ONE - CYCLIC YARN CHARACTERISTICS AT EXTENSION
(Savez inženjera i tehničara tekstilaca Srbije, 1999)
Ispitivane su jednociklične karakteristike pređa pri istezanju. Primenjen je postupak sa konstantnim opterećenjem u prvoj fazi ciklusa opterećenje - rasterećenje - odmor. Upoređivani su rezultati određivanja relaksacionih ...
