| | Tetraethylammonium hydroxide Usage And Synthesis |
| Chemical Properties | colourless liquid | | Uses | 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. | | General Description | The product is 20wt.% solution of tetraethylammonium hydroxide (TEA hydroxide, TENOH) in H2O. TEA hydroxide is a quaternary ammonium hydroxide (QAH). It participates in the synthesis of zeolite beta. TENOH peptized titania aqueous sols have been employed in the preparation of nanocrystalline anatase films. | | Hazard | Strong irritant to skin and tissue. |
