Product Name:Tetraethylammonium hydroxide
English Name:Tetraethylammonium hydroxide
CAS No.:77-98-5
Aliases:Tetraethylammonium hydroxide solution, TEAOH
Molecular Formula:C8H21NO
Physical Properties:Colorless to light yellow transparent liquid, commonly available as 25% or 35% aqueous solution with strong alkalinity. It readily absorbs carbon dioxide from air and is corrosive and irritating. Density is approximately 1.02-1.04 g/cm³ (25% aqueous solution). Miscible with water and ethanol. The anhydrous form is a white crystalline solid with a melting point of about 49-52°C (hydrate form).
Uses:Used as a phase transfer catalyst in organic synthesis, commonly applied in alkylation, esterification and other reactions. Also serves as a template-directing agent in molecular sieve synthesis, as well as a developer and cleaning agent in the electronics industry. Additionally, it can be used as an alkaline reagent for pH adjustment.
Technical Specifications:
Molecular weight: 147.26
Concentration: 25% aqueous solution or 35% aqueous solution (customizable)
Density: approx. 1.02-1.04 g/cm³ (25% aqueous solution)
Appearance: colorless to light yellow transparent liquid
Strongly alkaline, readily absorbs carbon dioxide
