Synthesis and Properties of a Hydrolysis Resistant Cationic Trisiloxane Surfactant

In order to improve the hydrolysis resistant ability (HRA) of trisiloxane surfactants, a new kind of quaternary ammonium salt cationic trisiloxane surfactant (QASCTSS) was synthesized in three steps and investigated. The chemical structure of QASCTSS was characterized by Fourier transform infrared s...

Description
Summary:In order to improve the hydrolysis resistant ability (HRA) of trisiloxane surfactants, a new kind of quaternary ammonium salt cationic trisiloxane surfactant (QASCTSS) was synthesized in three steps and investigated. The chemical structure of QASCTSS was characterized by Fourier transform infrared spectroscopy and proton nuclear magnetic resonance. Compared with normal trisiloxane surfactants, QASCTSS exhibits a lower surface tension, especially under strong acid or alkaline conditions. This was attributed to the protection for Si–O backbone from the quaternized side chain, and some improvement in HRA is seen in acidic conditions with ethyl instead of methyl side chains on the quaternary structure.
