Beschreibung

Allgemeine Beschreibung

tert-Butylamine (TBA) is an aliphatic primary amine. Its enthalpy of combustion and formation has been studied.[1] Its gas phase acidity[2] and gas phase basicity has been evaluated.[3] The ozonation of tert-butylamine has been reported.[4] Its influence on the aqueous beta-cyclodextrin (β-CD): pyrene complex has been examined by steady-state fluorescence measurements.[5]

Anwendung

tert-Butylamine (t-butylamine) may be used in the synthesis of Zn₂-SnO₄ nanoparticles.[6] It may be used to terminate the polymerization reaction during the synthesis of the following polymers (DAB =1,4-diaminobutane, BA=Boronic acid , PAA=functional poly(amido amine), ABOL=4-aminobutanol, Bn=Benzyl):[7]

• (DAB-BA-PAA)
• (ABOL-BA-PAA)
• (DAB-Bn-PAA)

tert-Butylamine (TBA) is suitable for use as an indicator molecule in the study of NMR-based pH determination method, free of glass electrode errors in highly basic media.[8] It is suitable for use in the synthesis of methyl β-ketophosphonate[9], titanium dioxide nanoparticles (TiO₂ NPs)[10][11] and samarium oxide (Sm₂O₃) nanospheres and nanorods.[12] It may be used in the following studies:

• As liquid hydrocarbon promoter in the systematic study on methane hydrate formation and dissociation.[13]
• As an example in the study of the effect of amines in influencing atmospheric H₂SO₄-H₂O nucleation.[14]
• Hydroamination of terminal alkynes.[15]
• To measure the surface acidity of solid catalysts by temperature-programmed desorption.[16]
• As a reductive nitrogen source in the atomic layer deposition technique used to deposit TaN thin films from TaCl₅ and TaBr₅.[17]
