Mass spectrometric investigations of some N‐cycloalkyl and N‐aryl fluoroacetamides
(Wiley, Hoboken, 1995)
The electron‐ionization induced mass spectra of some N‐monosubstituted fluoroacetamides of the general formula FCH2CONHR, in which the substituent R is (C3C7) cycloalkyl, phenyl, 4‐methylphenyl, 4‐carbo‐methoxyphenyl, ...
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 ...
Experimental and theoretical study of molecular H-complexes of ketones with diphenyl-p-chlorophenyl carbinol
(Elsevier, Amsterdam, 1992)
The interaction between hydroxy-diphenyl-[4-chlorophenyl]-methane and some typical ketones was studied both in theoretical and experimental ways. It was concluded that the Cl-substituted phenyl group contributes to the ...
The retention behavior of some anilides on unconventional TLC supports
(Akademiai Kiado Zrt, Budapest, 1997)
The TLC retention behavior of formanilide and I substituted acetanilides on starch and cellulose layers has been studied using aqueous mobile phases with methanol, acetonitrile, acetone, and 1-propanol as modifiers, R-Mw ...
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 ...
