I-phthalic anhydride
Iphrofayili yomkhiqizo
I-Phthalic anhydride, inhlanganisela ye-organic enefomula yamakhemikhali i-C8H4O3, iyi-cyclic acid anhydride eyakhiwe ukuphelelwa amanzi emzimbeni kwama-molecule e-phthalic acid. I-crystalline powder emhlophe, engancibiliki emanzini abandayo, incibilika kancane emanzini ashisayo, i-ether, incibilika ku-ethanol, i-pyridine, i-benzene, i-carbon disulfide, njll., futhi iyikhemikhali ebalulekile ye-organic material eluhlaza. Kuyingxenye ebalulekile yokulungiswa kwe-phthalate plasticizers, i-coatings, i-saccharin, odayi kanye nezinhlanganisela eziphilayo.
Inkomba Yezobuchwepheshe

Inkambu yohlelo lokusebenza:
I-Phthalic anhydride iyinto ebalulekile yamakhemikhali ephilayo futhi iyingxenye ebalulekile yokulungisa amapulasitiki e-phthalate, okokunamathela, i-saccharin, odayi nezinhlanganisela eziphilayo.
