2,4-Dihydroxybenzophenone CAS 131-56-6
I-2,4-Dihydroxybenzophenone yikristale ephaphathekileyo ye-acicular okanye umgubo omhlophe. Indawo yokunyibilika 142.6-144.6℃. Ukunyibilika kwi-25℃ (g /100 ml isinyibilikisi) : iacetone >50, benzene 1, ethanol >50 amanzi <0.5, n-heptane <0.5.2,4-Dihydroxybenzophenone inokunyibilika okuncinci kakhulu emanzini kwaye ayiboliswa yi-alkali exubileyo. kunye ne-asidi egxininisiweyo.
