(Quest Heated ATR) AN21-09: Phase Behaviour of Stearic-Acid Triethanolamine Soap on the Specac Heated Puck for Quest

CH2 Symmetric stretch peak position variation with temperature,
showing the thermotropic behaviour

Investigating the thermotropic behaviour of acid-soap mixtures.

The Quest ATR Heated Puck is an accessory for temperature-controlled experiments such as thermotropic phase change in materials and chemical systems. As a proof of performance, we have chosen a past study to replicate. Pudney et al. reported an ATR study of the phase behaviour of stearic acid-triethanolamine soap, from 0-100% neutralization of the acid [1]. Such compounds are commercially important and in widespread use in the soap industry.
