4,4'-(4,4'-ISOPROPYLIDENEDIPHENOXY)BIS(PHTHALIC ANHYDRIDE) Chemical Properties,Uses,Production
Description
4,4'-(4,4'-Isopropylidenediphenoxy)diphthalic Anhydride (BPADA) is a diphthalic anhydride structural unit with a core of bisphenol A. BPADA is a precursor for the synthesis of polyimides, which are highly thermally stable and have strong mechanical properties using their bisphenol A core. Polyimide films synthesised from this molecule are incompletely conjugated and therefore have high optical transparency. With their isometric stretchability and high glass transition temperature (Tg = 207 °C), these films are ideal for flexible display substrates. In addition to their high heat resistance, the polyimides are chemically inert and can be used as ion transport membranes in fuel cells.BPADA can also be used to make aerogels that are superhydrophobic (Lotus effect).
Uses
4,4'-(4,4'-Isopropylidenediphenoxy)bis(phthalic anhydride) be used for the preparation of a polyimide material.
Preparation
4,4'-(4,4'-isopropylidenediphenoxy)bis(phthalic anhydride) can be synthesized from 4-chlorophthalic anhydride and bisphenol A. Mainly includes the following steps:(1) Chlorophenyl anhydride imide, synthesis of N-Phenyltetrachlorophthalimide;(2) the synthesis of bisphenol A disodium salt;(3) Nucleophilic substitution reaction in dipolar nonproton solvent;(4) hydrolysis to bisphenol A diether tetraic acid;(5) dehydration to 4,4'-(4,4'-isopropylidenediphenoxy)bis(phthalic anhydride).
