| 中文摘要 | 本研究係利用熱重量分析法來探討溫度、氣體、KOH之濃度、鹼金屬離子等變化對五氯酚及其衍生物之影響。結果以Li-PCP之熱穩定性最高,Na-PCP次之,K-PCP較低。氯氣、氧氣及過量之KOH對K-PCP之熱分解影響並不顯著。在活化能方面,由恆溫熱分析法求得Na-PCP及K-PCP分別為43.2 Kcal/mole及36.2 Kcal/mole。 |
| 英文摘要 | The prolysis of alkali metal pentachlorophenate salts has been studied from 110° to 700℃ by dynamic and isothermal thermogravimetric methods. The results have shown that the thermal stability of chlorophenate salts decreases in the following order: Li-PCP > Na-PCP > K-PCP. TG curves of K-PCP under nitrogen and air were very similar. Apparently, the major thermal reaction of k-PCP at elevated temperature conditions is not effected by oxygen. Nor does the presence of various amounts of KOH in the K-PCP appear to affect the thermal reaction. The kinetics of thermal degradation of Na-PCP and K-PCP were investigated by isothermal thermogravimetric analysis. The activation energies of Na-PCP and K-PCP were found to be 43.2 Kcal/mole and 36.2 Kcal/mole, respectively. |
