Anhydride Phthalic
Profaili ọja
Phthalic anhydride, agbo-ara Organic pẹlu agbekalẹ kemikali C8H4O3, jẹ anhydride cyclic acid ti a ṣẹda nipasẹ gbigbẹ ti awọn ohun elo phthalic acid. O jẹ lulú crystalline funfun kan, ti ko le yanju ninu omi tutu, diẹ ninu omi gbigbona, ether, tiotuka ni ethanol, pyridine, benzene, carbon disulfide, ati bẹbẹ lọ, ati pe o jẹ ohun elo aise kemikali pataki kan. O jẹ agbedemeji pataki fun igbaradi ti awọn ṣiṣu phthalate, awọn aṣọ, saccharin, awọn awọ ati awọn agbo ogun Organic.
