摘要
用热分析与气相色谱联用技术（ＴＡ－ＧＣ）研究ＫＨＣ２Ｏ４·Ｈ２Ｏ的热分解表明，在空气和氦气当中，开始时缓慢分解，放出结晶水。接着ＫＨＣ２Ｏ４快速分解成Ｋ２Ｃ２Ｏ４，并释放出一些气体产物：Ｏ２（分解初期）、ＣＯ、ＣＯ２和Ｈ２Ｏ。
; The thermal decomposition of KHC\-2O\-4H\-2O was investigated by means
of discontinuous simultaneous techniques of thermal analysis and gas chromatography (TAGC).
In air and helium the decomposition of KHC\-2O\-4H\-2O was initially a slow dehydration
process of the monohydrate, followed by a rapid decomposition of KHC\-2O\-4 to K\-2C\-2O\-4
with the production of some gaseous products, O\-2 (initial stage of decomposition), CO, CO\-2
and H\-2O. The decomposition mechanism of KHC\-2O\-4 was discussed.\=\;
