Application

DOS can be used as an aerosol material that can be used to investigate the filtration efficiency of polyvinylidene/silicon oxide (PVDF/SiO2) based fibrous membranes. It may be blended with PVC to form membranes that can be deposited on silver (Ag) based composites which can be used in the fabrication of ion-selective electrodes for chemical analysis. DOS may also be used in combination with PVC, chloride ionophore III, and tridodecylmethylammonium chloride for the development of chloride sensing films.

General description

Bis(2-ethylhexyl) sebacate, or dioctyl sebacate (DOS), is a non-polar plasticizer that has two ester groups that bond with cationic compounds. It is mainly used in the formation of thin plasticized polyvinyl chloride (PVC) based membranes.
