- 中文摘要: 硝酸類與木質化纖維質之化學反應中,於不同壓力之氮氣下,以熱能掃描儀來探討硝酸類之飛散性與侵蝕性。降低反應物飛散性之方法,宜增加壓力至800磅/平方吋,並於試料杯蓋上穿一小針孔(0.05?0.065公厘)。純鋁表面惰化處理, 在高?下反而對硝酸類之熱分解反應具有催化作用,因此進行此類化學反應之測定時,應使用純黃金製作之試料杯。
- 英文摘要: The volatile and corrosive nature of nitrates in the reactions with lignocellulosic materials was examined by DSC in nitrogen atmosphere at various pressures. The best procedure to minimize the volatile products would be to run the samples encapsulated with the lid provided with a small pin-hole (0.05 -0.065 mm) at 800 psig. The passive treatments on the plain aluminum sample holders did in some way catalyze the decomposition of nitrates at elevated temperatures. The reliable data could only be obtained by using gold sample holders.
