Microwave Synthesis of Quaternary Ammonium Salts [PDF]

open access: yesMolecules, 2008
The microwave synthesis of several quaternary ammonium salts is described. The synthesis provides comparable or better yields than published methods with reduced reaction times and in the absence of solvent.

Mutual solubility of ammonium perrhenate in solutions containing ammonium salts [PDF]

open access: yesScientific Reports
Mutual solubility measurements were carried out for three multi-component systems of ammonium perrhenate (NH4ReO4) and one of the ammonium salts (NH4NO3, NH4Cl or (NH4)2SO4) dissolved in water.

Increasing the production of gas condensate by using ammonium carbonate salts [PDF]

open access: yesE3S Web of Conferences, 2021
The work is devoted to the problem of increasing gas condensate production in gas condensate fields. It was found that ammonium carbonate salts, in the absence of calcium chloride type waters, interact with carbonate rocks, increase the permeability of ...

Hygroscopic behavior of atmospherically relevant water-soluble carboxylic salts and their influence on the water uptake of ammonium sulfate [PDF]

open access: yesAtmospheric Chemistry and Physics, 2011
The hygroscopic behavior of atmospherically relevant water-soluble carboxylic salts and their effects on ammonium sulfate were investigated using a hygroscopicity tandem differential mobility analyzer (H-TDMA).

Amine exchange into ammonium bisulfate and ammonium nitrate nuclei [PDF]

open access: yesAtmospheric Chemistry and Physics, 2010
The exchange kinetics and thermodynamics of amines for ammonia in small (1–2 nm diameter) ammonium bisulfate and ammonium nitrate clusters were investigated using electrospray ionization Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR-

Synthesis of Chiral Helic[1]triptycene[3]arenes and Their Enantioselective Recognition towards Chiral Guests Containing Aminoindan Groups

open access: yesMolecules, 2021
Starting from the enantiopure precursors, a pair of chiral macrocyclic arenes named helic[1]triptycene[3]arenes were conveniently synthesized. The circular dichroism (CD) spectra of the enantiomeric macrocyclic arenes exhibited mirror images, and the X ...
