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).
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%.
25kg/ 3-in-1 peeke hiato pepa-kirihou, peeke raranga ranei, peere 25kg/ peere pepa (φ410×480mm); Packaging rite ki ngā whakaritenga kiritaki;
Rokiroki i roto i te ipu hau i roto i te wahi matao, maroke, hau pai atu i te ahi me te mura.
