Anwendungen & Verwendung
Verwenden
Tetraethylammonium hydroxide is a strong organic base and finds applications in photovoltaic chemicals, advanced ceramics, flat panel display chemicals, selective etching and transesterification catalysts. Its solution (35 wt. % in H2O) may be used as an organic structure-directing agent (SDA)/template in the synthesis of mesoporous molecular sieves and zeolite samples.
