Description

Application

Tetraoctylammonium hydroxide solution can be used as:

• A lipophilic base in the study of its effect on optical pCO₂ sensors.
• A lipophilic organic base in the preparation of nanobeads, which are used as sensors for the detection of acidic and basic gases.
• 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.

Other Notes

Very lipophilic phase-transfer agent; employed in a carbon dioxide optical sensor
