Popis

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.

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.
