Tetraethylammonium hydroxide Chemical Properties,Uses,Production
Chemical Properties
colourless liquid
Uses
Tetraethylammonium hydroxide 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.
Uses
Alkaline catalyst, solvent for certain types of dyes, metal-plating solutions.
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.
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.
