Conformations of unsymmetrical N-t-butyl-N-substituted 2-phenylacetamides
(Elsevier B.V., 1997)
Various N-t-butyl-N-substituted 2-phenylacetamides, PhCH2CON(t-Bu)R, wherein R is methyl, ethyl, n-propyl, n-butyl, i-propyl, phenyl and cyclohexyl, were synthesized, Depending on the kind of substituent on the nitrogen ...
Thermal shock behavior of alumina based refractories: fracture resistance parameters and water quench test
(Elsevier, Amsterdam, 1999)
The prediction of refractories thermal shock behavior can be estimated on two basis: heat transfer conditions and/or fracture mechanics concept. Materials considered in our analysis were alumina based refractories with ...
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 ...
Preparation and Properties of Sodalite-Type Aluminophosphates Containing Silicon, Cobalt and Zinc
(CSIRO PUBLISHING, 1991)
The SAPO, MeAPO and MeSAPO microporous materials (Me=Co2+ and/or 2n2+) having a sodalite structure have been obtained hydrothermally at 200°C in the presence of tetramethylammonium ion as the template. The SAPO and MeSAPO ...
Infinite dilution activity coefficients of organic solutes in N,N-diethyldodecanamide
(Amer Chemical Soc, Washington, 1994)
Infinite dilution activity coefficients of pentane, hexane, heptane, cyclohexane, benzene, tetrachloromethane, dichloromethane, diethyl ether, tetrahydrofuran, acetone, ethyl acetate and methanol in N,N-diethyldodecanamide ...
A kinetic study of the system phthalocyanine-copper(II) chloride-sulfuric acid
(Elsevier Science Sa, Lausanne, 1990)
In solutions of phthalocyanine, H2Pc, (c = 1-3 × 10-5 mol dm-3) and copper(II) chloride (c ≈ 10-3 mol dm-3) in sulfuric acid (c = 16-18 mol dm-3), two pseudo first-order reactions take place: (1) decomposition of H2Pc; (2) ...
Synthesis of some new N-monosubstituted fluoroacetamides
(Journal of Fluorine Chemistry, 1992)
Twenty new N-monosubstituted fluoroacetamides with potential toxicological properties have been synthesized by acylation of the corresponding amines with fluoroacetyl chloride. The substituents were cycloalkyl or various ...
Synthesis and FTIR spectroscopic study of some N-monosubstituted propanamides
(Elsevier, Amsterdam, 1997)
In the present work we investigated the conformations of some N-mono-substituted propanamides of general formula CH3CH2CONHR, wherein R is chosen from n-(C-1-C-9)alkyl, cyclo(C-3-C-6)alkyl, some branched (C-3-C-6)alkyl or ...
Conformations in unsymmetrically N-n-propyl-N-substituted 2-phenylacetamides
(Elsevier, Amsterdam, 1992)
As a part of a study on the structural characteristics of some new various N-alkyl-N-substituted 2-phenylacetamides the infrared and 1H N.M.R. spectra were obtained and interpreted. The synthesis of a various N-n-propyl-N-alkyl ...
