Tono Hua

He takawaenga nui mo nga waikano marara.Koia hoki te takawaenga o te rongoa tātaritanga hou ubiquitin (kaiwhakarere rereke X-ray);Ka whakamahia hoki ki te whakahiato i tetahi puhui rongoa hou e pa ana ki te waikawa glycolinic inhibitor PDE IV;Ka whakamahia hoki hei takawaenga mo nga waikano marara (nga waikano azo kikorangi).

whakaputanga

Ko te waikawa sulfuric (104.3mL, 1.92mol) kua whakauruhia ki roto i nga ipu e toru, katahi ka tapirihia te waikawa isophthalic (40g, 0.24mol), ka whakakorikoria, ka whakamahana ki te 60 ℃, ka mau mo te 0.5h, me te 60% waikawa nitric (37.8g, 0.36). mol) i tapirihia ki te whakahaere i te tohu whakatere topata.Tāpirihia i roto i te 2 haora.I muri i te taapiri, te tauhohenga tiaki wera i te 60 ℃ mo te 2 haora.Matao ki raro iho i te 50 ° C, katahi ka tapirihia te 100mL wai.I whakamataohia te rauemi ki te pāmahana rūma, ringihia ki roto i te tātari, maminga ki te tango i te waikawa para, ka horoia te keke tātari ki te wai, ka whakahekehia ki te rerystallize, a ko te hua ma he 34.6 karamu, ko te hua ko te 68.4%.
