Temperature-programmed desorption mass spectrometric study of the surface properties of glassy carbon
(Wiley, Hoboken, 1996)
The temperature-programmed desorption (TPD) method combined with mass spectrometric analysis has been applied to the characterization of glassy carbon (GC) and modified glassy carbon surfaces. Five different samples of GC ...
Phase transfer ethylation of N-substituted amides of phenylacetic acid
(Mezhdunarodnaya Kniga, Moscow, 1998)
On the formation of CoAPSO-44
(Butterworth-Heinemann, 1992)
Hydrothermal synthesis of CoAPSO-44 in the presence of cyclohexylamine (CHA) as the template is generally accompanied by the formation of an unknown phase, “Co(APSO)N.” Electronic spectroscopy indicates that CO(APSO)N ...
Resistance parameters and water quench test as criteria of thermal shock behaviour of alumina based refractories
(Taylor & Francis Ltd, Abingdon, 1999)
The materials investigated were five alumina based commercial refractories with different contents of Al2O3 + TiO2 from 28 to 78%. Thermal (k thermal conductivity, alpha coefficient of thermal expansion) and mechanical (E ...
A novel open framework zincophosphate: Synthesis and characterization
(Elsevier Science Inc., 1995)
The crystallization of a reactive zincophosphate gel (which may contain Co(ll) component) in the presence of sodium cations at ambient temperature and pressure yielded products (abbreviated ZnPO-HEX or CoZnPO-HEX) with a ...
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 ...
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 ...
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 ...
