Development of Amine Capillary Column Applied to the Analysis of Basic Compounds by Electrochromatography
(Scientific Research, 2015-12)
An amine capillary column was developed in a fused-silica capillary as stationary phase and appliedto separation of basic compounds by capillary electrochromatography (CEC). The functionalizedcapillary was prepared by ...
On the Nucleophilicity of Boryllithium Compounds. A Theoretical Study
(AMER CHEMICAL SOC, 2009)
Boron compounds are widely used in synthetic chemistry. The synthesis of the compounds is relatively easy, presenting thermodynamic stability and synthetic versatility. Almost all of them show electrophilic reactivity. ...
Inclusion compounds of α-cyclodextrin with alkylthiols
(Sociedad Chilena de Quimica, 2008)
We report the formation of α-cyclodextrin (αCD) inclusion compounds with octanethiol (OT), decanethiol (DT) and dodecanethiol (DDT). Elemental Microanalysis, 1H-NMR solution, Scanning Electronic Microscopy (SEM) and Powder ...
Preparation and thermal behavior of mixture of basic carbonate and 4-dimethylaminocinnamylidenepyruvate with lanthanides (III) and yttrium (III) in the solid state
(Editora Unesp, 1999-01-01)
Solid Ln-OKCO3-DMCP compounds, where Ln represents lanthanides (III) and yttrium (III) ions and DMCP is the anion 4-dimethyiaminocinnamylidenepyruvate, have been prepared. Thermogravimetry, derivative thermogravimetry (TG, ...

Scales of basicity based on thermochemical data of adducts
(Kluwer Academic PublDordrechtHolanda, 2002)
Frankenwords: a cognitive perspective on the interpretation of NOUN-NOUN compounds in English
(Universidad de Chile, 2017)
NOUN - NOUN compounds have been extensively studied in the past, not only for the reason that they possess a remarkable degree of diversity regarding semantic relationships between their constituents but also because of ...
Inclusion compounds of α- and γ-cyclodextrins with n-alkylamine (n= 12, 18)
(2004)
We report the synthesis of α- and γ-ciclodextrin inclusion compounds with dodecylamine (DDA), and octadecylamine (ODA). Elemental analysis, 13C CP- MAS NMR spectroscopy, scanning electron microscopy (SEM) and powder X-ray ...
Synthesis and structural aspects of urea/dialkylamine inclusion compounds
(Kluwer Academic Publishers, 1995)
The synthesis and structural aspects of urea host-guest inclusion compounds containing linear secondary alkylamines (dibutyl-,dipentyl-, dihexyl-, dioctyl-) at 25°C are reported. Elemental analysis,13C CP-MAS NMR and1H-NMR ...
Determination of Linear Response in the Detection of Aroma Compounds by Atmospheric Pressure Ionization−Mass Spectrometry (API-MS)
(American Chemical Society, 2005-02)
Linearity and detection thresholds of atmospheric pressure ionization−mass spectrometry (API-MS) were determined for 11 aroma compounds in air at concentrations ranging from 50 ppb to ∼450 ppm (moles of volatile per mole ...
