Phthalic anhydride
Muuqaalka badeecada
Phthalic anhydride, oo ah iskudhis organic ah oo leh qaacido kiimikaad C8H4O3, waa anhydride aashitada cyclic oo ay samaysay fuuqbaxa unugyada phthalic acid. Waa budo crystalline cad, oo aan lagu milmin biyo qabow, wax yar ku milma biyaha kulul, ether, milma ethanol, pyridine, benzene, carbon disulfide, iwm, waana walxo kiimiko ah oo muhiim ah oo ceeriin ah. Waa dhexdhexaad muhiim u ah diyaarinta balaastikada phthalate, dahaarka, saccharin, dheeha iyo xeryahooda organic.
