| Abstract: | In the paper, contrastive experiments about acidity, temperature and different reflection time were performed. The factors influencing catalytic system steadiness were related to mixed-acids, from which the best conditions on catalytic system relative steadiness were confirmed. Many samples were determined by the method. The results obtained are in good agreement with the certified values. |
