Temperature dependence of proton chemical shifts of aqueous sodium fluoride, sodium hydroxide, and tetramethylammonium hydroxide: the internal tetramethylammonium ion standard

Journal of the Chemical Society, Dalton Transactions, 1973
Proton chemical shifts have been determined over a range of temperature for water, and for aqueous sodium fluoride and sodium or tetramethylammonium hydroxide solutions using Me4N+ as an internal standard. The water results agree closely with those of Hindman and confirm that the shift temperature dependence is not constant over the range 0–100 °C. The

Raman study on molecular motion in tetramethylammonium hydroxide pentahydrate

The Journal of Chemical Physics, 1991
The Raman spectrum as well as conductivity and differential-thermal-analysis (DTA) thermogram of tetramethylammonium hydroxide pentahydrate was observed at various temperatures in order to investigate molecular motion in relation to conductivity and a phase transition.

A Raman Study of Etching Silicon in Aqueous Tetramethylammonium Hydroxide

Journal of The Electrochemical Society, 1998
The silicon etching process in tetramethylammonium hydroxide (TMAH) has been characterized using Raman scattering measurements. The measurements were carried out for 20 and 2% TMAH at different temperatures and for 20% TMAH in situ during the etching process.

Solid-state metal hydride batteries using tetramethylammonium hydroxide pentahydrate

Solid State Ionics, 1992
Abstract A new solid electrolyte, tetramethylammonium hydroxide pentahydrate, was applied to a nickel oxyhydroxide-metal hydride (NiOOH/MH) battery and a manganese dioxide-metal hydride (MnO 2 /MH) battery, which were prepared by impregnating the melt of the solid electrolyte into the battery components.

Tetramethylammonium hydroxide thermochemolysis of guaiacyl–syringyl and guaiacyl dehydrogenation polymers

Organic Geochemistry, 2005
Abstract Tetramethylammonium hydroxide thermochemolysis of lignin was investigated using guaiacyl–syringyl and guaiacyl dehydrogenation polymers. The guaiacyl–syringyl mixed polymer provided: (1) 1-(3,4-dimethoxyphenyl)-1,2,3-trimethoxypropane isomers ( 11 / 12 ) and 1-(3,4,5-trimethoxyphenyl)-1,2,3-trimethoxypropane isomers ( 15 / 16 ) as β-aryl ...

Tetramethylammonium hydroxide (TMAH) thermochemolysis of 2-arylcoumaran lignin model compounds

Journal of Analytical and Applied Pyrolysis, 2009
Abstract Phenolic 2-arylcoumarans 1 – 6 were used to examine the behaviors of β-5 subunits in lignin during tetramethylammonium hydroxide (TMAH) thermochemolysis. Products were monitored by gas chromatography/mass spectrometry. The process predominantly provided dimeric products with the opened hydrofuran ring. Substituent changes at the γ-position
