Chinhu chakakosha chepakati chekuparadzira dhayi. Iyo zvakare yepakati peiyo diagnostic drug new ubiquitin (X-ray musiyano mumiririri); Inoshandiswawo kugadzira riwaya remushonga wemushonga wakavakirwa paPDE IV inhibitor glycolinic acid; Inoshandiswawo seyepakati yekuparadzira dhayi (blue azo dyes).
Yakaiswa sulfuric acid (104.3mL, 1.92mol) yakawedzerwa mumabhodhoro matatu, ipapo isophthalic acid (40g, 0.24mol) yakawedzerwa, yakamutswa uye inopisa kusvika 60 ℃, yakachengetwa kwe0.5h, uye 60% nitric acid (37.8g, 0.36) mol) yakawedzerwa kudzora dhigirii rekumhanyisa kudonha. Wedzera mumaawa maviri. Mushure mekuwedzera, kupisa kwekuchengetedza maitiro pa60 ℃ kwemaawa maviri. Kutonhora kusvika pasi pe50 ° C, wobva wawedzera 100mL yemvura. Nyaya yacho yakanyoroveswa kusvika kune tembiricha yekamuri, yakadururirwa musefa, yakapombwa kuti ibvise marara asidhi, keke resefa yakashambidzwa nemvura, yakanyungudutswa kuti iite recrystallize, uye chigadzirwa chichena chaive 34.6 gramu, goho raive 68,4%.
25kg/ 3-in-1 bepa-purasitiki rinoumbwa bhegi, kana bhegi rakarukwa, kana 25kg/ makadhibhokisi bhaketi (φ410 × 480mm); Packaging maererano nezvinodiwa nevatengi;
Chengetedza mumudziyo usingapindi mhepo munzvimbo inotonhorera, yakaoma, ine mhepo yakanaka kure nemoto uye zvinobvira.
