Dhexdhexaad muhiim u ah midabada kala firdhisan. Sidoo kale waa dhexdhexaadinta dawada ogaanshaha ubiquitin cusub (wakiilada isbarbardhiga raajada); Waxa kale oo loo isticmaalaa in lagu soo saaro xarun cusub oo daroogo ah oo ku salaysan PDE IV inhibitor glycolinic acid; Waxa kale oo loo istcimaalaa dhex dhexaad ahaan dheeha kala firdhisan (midabka azo buluuga ah).
Sulfuric acid (104.3mL, 1.92mol) ayaa lagu daray saddex dhalo, ka dibna isophthalic acid (40g, 0.24mol) ayaa lagu daray, walaaqay oo la kuley 60 ℃, oo lagu hayo 0.5h, iyo 60% nitric acid (37.8g, 0.36) mol) ayaa lagu daray si loo xakameeyo heerka dardargelinta dhibicda. Ku dar 2 saacadood gudahood. Intaa ka dib, falcelinta ilaalinta kulaylka 60 ℃ 2 saacadood. Ku qabooji heer ka hooseeya 50 ° C, ka dibna ku dar 100 ml oo biyo ah. Maaddada ayaa la qaboojiyey heerkulka qolka, lagu shubay shaandhada, bamgareynta si loo soo saaro aashitada qashinka, keega shaandhada ayaa lagu dhaqay biyo, daadi si dib loogu celiyo, iyo badeecada cad waxay ahayd 34.6 garaam, wax-soo-saarku wuxuu ahaa 68.4%.
25kg/ 3-in-1 warqad-caag ah bac isku dhafan, ama bac tolan, ama 25kg/ baaldi kartoonada (φ410×480mm); Baakadaha si waafaqsan shuruudaha macaamiisha;
Ku kaydi weelka hawo-mareenka ah meel qabow, engegan, hawo fiican leh oo ka fog dabka iyo waxyaabaha gubanaya.
