摘要
本文用热重、微分热重和差热分析法研究了 X 射线分光晶体 KAP、RAP 和 TAP 热稳定性问题。测定结果表明,KAP、RAP 和 TAP 开始分解失重温度分别为222℃、231℃、186℃.
The thermal decompositions of KAP,RAP and TAP of X-rayanalyzing crystals were investigated by TG-DTG and DTA methods.The resu-lts showed that the thermal decompositions of KAP,RAP and TAP began at222℃,231℃ and 186℃ respectively.Their thermal decompositions proceededin two stages which include:(1) the fbrmation of dipotassium (dirubidium,dithallium) phthalate and the volatilisation of phthalic anhydride and water;(2) the decompositions of dipotassium (dirubidium) phthalate to yield vola-tile products and a residue potassium (rubidium) carbonate and carbon (or“tar”),the decomposition of dithallium phthalate seems to be complex.
