Isiphakathi esibalulekile sokuhlakaza odayi. Futhi iyindawo emaphakathi yomuthi wokuxilonga i-ubiquitin entsha (i-ejenti yokuqhathanisa ye-X-ray); Ibuye isetshenziselwe ukuhlanganisa inhlanganisela yezidakamizwa ezinoveli esekelwe ku-PDE IV inhibitor glycolinic acid; Ibuye isetshenziswe njengendawo ephakathi kodayi abahlakazayo (amadayi we-azo aluhlaza okwesibhakabhaka).
I-sulfuric acid egxilile (104.3mL, 1.92mol) yengezwa emabhodleleni amathathu, kwase kwengezwa i-isophthalic acid (40g, 0.24mol), yanyakaziswa futhi yashiswa ibe ngu-60 ℃, ebanjelwe u-0.5h, kanye no-60% nitric acid (37.8g, 0.36) mol) yengezwe ukulawula idigri yokusheshisa amaconsi. Yengeze emahoreni angu-2. Ngemuva kwalokho, ukusabela kokugcina ukushisa ku-60 ℃ amahora ama-2. Phola ube ngaphansi kuka-50 ° C, bese ufaka u-100mL wamanzi. Impahla ipholile ekamelweni lokushisa, ithululelwe esihlungi, iphonswe ukuze isuse i-asidi yemfucuza, ikhekhe lokuhlunga lihlanjululwe ngamanzi, likhishwe ukuze liphinde likhanye, futhi umkhiqizo omhlophe wawungamagremu angu-34.6, isivuno sasingu-68.4%.
25kg/ 3-in-1 isikhwama esiyinhlanganisela yephepha-plastiki, noma isikhwama elukiwe, noma 25kg/ amakhadibhodi ibhakede (φ410×480mm); Ukupakisha ngokwezidingo zamakhasimende;
Gcina esitsheni esingangeni moya endaweni epholile, eyomile, enomoya omuhle kude nomlilo nezinto ezivuthayo.
