Phthalic anhydride
Bayanin samfur
Phthalic anhydride, kwayar halitta tare da dabarar sinadarai C8H4O3, wani cyclic acid anhydride ne wanda aka samu ta hanyar bushewar kwayoyin phthalic acid. Farin lu'ulu'un foda ne, wanda ba zai iya narkewa a cikin ruwan sanyi, mai ɗanɗano shi cikin ruwan zafi, ether, mai narkewa a cikin ethanol, pyridine, benzene, carbon disulfide, da sauransu, kuma yana da mahimmancin sinadari mai ƙarfi. Yana da mahimmanci mai mahimmanci don shirye-shiryen phthalate plasticizers, coatings, saccharin, dyes da kwayoyin mahadi.
