Other Notes

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

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.

A sensing configuration for the real-time monitoring, detection, and quantification of dissolved carbon dioxide (dCO2) was developed for aquaculture and other applications in freshwater and saline water. A chemical sensing membrane, based on a colorimetric indicator, is combined with multimode
(Liquid+ liquid) equilibrium data for the separation of 2, 3-butanediol from aqueous streams using tetraoctyl ammonium 2-methyl-1-naphthoate
