Acide yibanze ya sulfurike (104.3mL, 1.92mol) yongewemo mumacupa atatu, hanyuma aside isofthalic (40g, 0.24mol) yongerwamo, irashyushya kandi ishyuha kugeza kuri 60 ℃, ifata 0.5h, na 60% acide nitric (37.8g, 0.36) mol) yongeyeho kugenzura urwego rwihuta. 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%.
