说明

General description

四甲基氢氧化铵（TMAH）是一种市售的季铵碱，其碱度明显高于氢氧化铵。

Application

四甲基氢氧化铵溶液（在 H₂O 中为 10 wt.%）可用作：

一种在 IPA 中使用 2-（3，4-环氧环己基）乙基三甲氧基硅烷（ECTMS）通过溶胶-凝胶法合成环氧多面体低聚倍半硅氧烷（EPOSS）的反应物。
一种用于修饰 SnO₂ 纳米晶体的离子液体，可作为钙钛矿太阳能电池中的有效电子传输层。

TMAH 由于其高硅蚀刻速率，也可用作硅的各向异性蚀刻剂。使用 TMAH 的主要优点是，由于不存在碱离子，它不会对电路造成危险。

Hard Coating Materials Based on Photo-Reactive Silsesquioxane for Flexible Application: Improvement of Flexible and Hardness Properties by High Molecular Weight.

Jong Tae Leem et al.

Polymers, 13(10) (2021-06-03)

EPOSS of polyhedral oligomeric silsesquioxanes (POSS) mixture structure and LPSQ of ladder-like polysilsesquioxane (LPSQ) structure were synthesized via sol-gel reaction. EPSQ had a high molecular weight due to polycondensation by potassium carbonate. The EPSQ film showed uniform surface morphology due

Tetramethylammonium hydroxide as a reagent for complex mixture analysis by negative ion electrospray ionization mass spectrometry.

Vladislav V Lobodin et al.

Analytical chemistry, 85(16), 7803-7808 (2013-08-08)

Ultrahigh-resolution Fourier transform ion cyclotron resonance mass spectrometry (FTICR MS) enables the direct characterization of complex mixtures without prior fractionation. High mass resolution can distinguish peaks separated by as little as 1.1 mDa), and high mass accuracy enables assignment of

Dissolution kinetics and mechanisms at dolomite-water interfaces: effects of electrolyte specific ionic strength.

Man Xu et al.

Environmental science & technology, 47(1), 110-118 (2012-06-12)

Elucidating dissolution kinetics and mechanisms at carbonate mineral-water interfaces is essential to many environmental and geochemical processes, including geologic CO(2) sequestration in deep aquifers. In the present work, effects of background electrolytes on dolomite (CaMg(CO(3))(2)) reactivity were investigated by measuring
