General description

Octamethyltrisiloxane, commonly referred to as octamethylcyclotetrasiloxane, falls under the category of siloxanes. Its versatile applications include serving as a solvent, coupling agent, and surface tension modifier in various industries. Furthermore, it plays a significant role in the production of adhesives, sealants, and lubricants.

Application

Octamethyltrisiloxane is used as a solvent for good dispersion of styrene and polydimethylsiloxane (PDMS), which are used in the fabrication of perovskite barium titanate inverse opal films.

Most of the reported methods for the analysis of volatile methylsiloxanes focus on their environmental fate or possible health effects, aiming at trace level analysis by using direct injection gas chromatography. However, system contamination as carry over and side reactions
