Beschreibung

Anwendung

Tetraoctylammonium hydroxide solution can be used as:

• A lipophilic base in the study of its effect on optical pCO₂ sensors.[1]
• A lipophilic organic base in the preparation of nanobeads, which are used as sensors for the detection of acidic and basic gases.[2]
• A starting material for the preparation of ionic liquid named tetraoctylammonium 2-methyl-1-naphthoate, which is used in the extraction of 2,3-butanediol from H₂O.[3]
