Acide ya sulfurike yibanze (104.3mL, 1.92mol) yongewemo mumacupa atatu, hanyuma aside isophthalic (40g, 0.24mol) yongerwamo, irashyuha kandi ishyuha kugeza kuri 60 ℃, ifata 0.5h, na aside nitric 60% (37.8g, 0.36mol) yongerwaho kugirango igabanye umuvuduko w umuvuduko wibitonyanga. Ongeraho mumasaha 2. Nyuma yo kongeramo, ubushyuhe bwo kubika ubushyuhe kuri 60 ℃ kumasaha 2. Nkonje kugeza munsi ya 50 ° C, hanyuma ongeramo 100mL y'amazi. Ibikoresho byakonjeshejwe ubushyuhe bwicyumba, bisukwa muyungurura, bipompa kugirango bikureho aside imyanda, cake yo kuyungurura yogejwe namazi, ayungurura kugirango yongere yongere, kandi ibicuruzwa byera byari garama 34,6, umusaruro wari 68.4%.
20Kg cyangwa 25Kg / indobo, indobo yamakarito, itondekanye umurongo wera hamwe n umufuka wa polyethylene wirabura. 2 ℃ -8 ℃ ahantu humye, hakonje, kure yububiko bworoshye, bwemewe kumyaka 2.
