Abstract

Siloxane oil with five different molar masses was synthesized via equilibrium ring-opening reaction of octamethylcyclotetrasiloxane (D4). The chemical structures of the five siloxane oils material were confirmed using both Nuclear Magnetic Resonance Spectroscopy (NMR) and Fourier-Transform Infrared Spectroscopy (FTIR) techniques and the molecular mass was determined using proton 1H-NMR as well as chromatographic analysis techniques.The High Performance Liquid Chromatography (HPLC) results obtained also showed that cyclic siloxane oils could be removed from the linear siloxane oils using vacuum distillation, and the molecular mass determined from 1H-NMR was smaller than the target molecular mass
