Title: Tetraethylammonium Hydroxide
CAS Registry Number: 77-98-5
Molecular Formula: C8H21NO
Molecular Weight: 147.26
Percent Composition: C 65.25%, H 14.37%, N 9.51%, O 10.86%
Line Formula: (C2H5)4NOH
Literature References: Made from the corresp halide by treating with silver oxide or with a soln of potassium hydroxide in methanol.
Properties: Marketed as an aq soln. A 10% soln has a d425 ~1.01. The free base is known only in soln or as hydrates. Dec on boiling. It is a very strong base readily absorbing CO2 from the air. The aq soln is colorless, odorless, bitter, caustic, strongly alkaline, and imparts a soapy feel to the skin. Keep well closed.
