Pyromellitic Dianhydride Usage And Synthesis
Chemical PropertiesWhite powder. Soluble in some organic solvents; hydrolyzes to the acid when exposed to moisture.
UsesPyromellitic dianhydride (PMDA) is employed as a curing agent for epoxy agent resins used for casting, laminating, the manufacture of moulding powders, adhesives and coatings.
Usespyromellitic dianhydride be used for preparation polyimide and epoxy resin material.
HazardSkin irritant.
Purification MethodsCrystallise the dianhydride from ethyl methyl ketone or dioxane. Dry, and sublime it in vacuo.[Beilstein 19 H 196, 19/5 V 407.]
