Abstract：Recently it has become a trend to modify AC by adding different additives in AC system. In the modification, it is a key question to know what kind of additives should be added. So, qualitatively deformulating the additives will certainly help the research on and development of modifying AC a lot. In this paper, TLC (Thin Layer Chromatograph) was used to separate and purify the unknown assistant blowing agent in AC blowing system. After that, FTIR-Microscope was used to indicate the functional group in the uncommon unknown compound. Through combination of FTIR analysis, elemental analysis and other physical and chemical analysis, the molecular structure of the unknown was deduced. Finally, by explaining the unknown compound’s MS spectra, the molecular structure of the unknown was confirmed further. The method can be extended to analyze other additives in AC blowing agent system whose various standard spectra are absent.
