Phthalic anhydride
Mbiri ya malonda
Phthalic anhydride, organic pawiri yokhala ndi chilinganizo chamankhwala C8H4O3, ndi cyclic acid anhydride yopangidwa ndi kuchepa kwa madzi m'thupi la mamolekyu a phthalic acid. Ndi ufa woyera wa crystalline, wosasungunuka m'madzi ozizira, osungunuka pang'ono m'madzi otentha, ether, sungunuka mu ethanol, pyridine, benzene, carbon disulfide, ndi zina zotero, ndipo ndizofunikira organic mankhwala zopangira. Ndikofunikira kwapakatikati pokonzekera mapulasitiki a phthalate, zokutira, saccharin, utoto ndi ma organic mankhwala.

Malo ogwiritsira ntchito:
Phthalic anhydride ndi chinthu chofunika kwambiri pakupanga mankhwala opangira mankhwala komanso chofunikira kwambiri pokonzekera phthalate plasticizers, zokutira, saccharin, utoto ndi mankhwala achilengedwe.
