Anhydride ea phthalic
Boemo ba sehlahisoa
Phthalic anhydride, motsoako oa manyolo o nang le foromo ea lik'hemik'hale C8H4O3, ke anhydride ea cyclic acid e entsoeng ka ho felloa ke metsi 'meleng oa limolek'hule tsa phthalic acid.Ke phofshoana e tšoeu ea crystalline, e sa qhibiliheng metsing a batang, e qhibilihang hanyenyane metsing a chesang, ether, e qhibilihang ka har'a ethanol, pyridine, benzene, carbon disulfide, joalo-joalo, 'me ke ntho ea bohlokoa ea lik'hemik'hale tse tala.Ke karolo ea bohlokoa ea ho lokisa li-plasticizers tsa phthalate, liaparo, saccharin, lidae le metsoako ea manyolo.
