Isiphakathi esibalulekileyo sokusasaza idayi. Ikwayindawo ephakathi kwiyeza lokuxilonga i-ubiquitin entsha (i-X-reyi yokuthelekisa i-agent); Ikwasetyenziselwa ukudibanisa i-compound yeziyobisi ezinoveli ngokusekelwe kwi-PDE IV inhibitor glycolinic acid; Ikwasetyenziswa njengendawo ephakathi yokusasaza idayi (i-azo dyes eluhlaza okwesibhakabhaka).
I-asidi ye-sulfuric egxininisiweyo (104.3mL, 1.92mol) yongezwa kwiibhotile ezintathu, emva koko isophthalic acid (40g, 0.24mol) yongezwa, ixutywe kwaye ishushu kwi-60 ℃, ibanjwe i-0.5h, kunye ne-60% ye-nitric acid (37.8g, 0.36) mol) yongezwa ukulawula iqondo lokukhawulezisa amathontsi. Yongeza kwiiyure ezi-2. Emva koko, ukusabela kokugcina ubushushu kwi-60 ℃ kwiiyure ezi-2. Phola ukuya ngaphantsi kwe 50 ° C, emva koko wongeze i-100mL yamanzi. Izinto eziphathekayo zipholile kwiqondo lokushisa, zithululelwe kwisihlunu, zixutywe ukuze zisuse i-asidi yenkunkuma, ikhekhe lokucoca lihlanjwe ngamanzi, lihlanjululwe ukuze lihlaziye, kwaye imveliso emhlophe yayiyi-34.6 grams, isivuno sasiyi-68.4%.
I-25kg / i-3-in-1 ye-paper-plastic composite bag, okanye isikhwama esilukiweyo, okanye i-25kg / ibhakethi yekhadibhodi (φ410 × 480mm); Ukupakishwa ngokweemfuno zabathengi;
Gcina kwisingxobo esingangeni moya kwindawo epholileyo, eyomileyo, nengena umoya kakuhle kude nomlilo nezinto ezinokutsha.
