Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 94790-35-9, Name is N-(Chloro(dimethylamino)methylene)-N-methylmethanaminium hexafluorophosphate(V), molecular formula is C5H12ClF6N2P, belongs to benzoxazole compound, is a common compound. In a patnet, author is Sun, Lin, once mentioned the new application about 94790-35-9, Formula: C5H12ClF6N2P.
Synthesis, characterization and structural thermally rearrangement of ortho-amide functional benzoxazine containing acetylene group
A novel ortho-amide functional benzoxazine monomer containing acetylene group has been synthesized in this study. The chemical structures of synthesized monomer are confirmed by H-1 and C-13 nuclear magnetic resonance (NMR) spectroscopy and Fourier transform infrared (FT-IR) spectroscopy. The polymerization behaviors including both ring-opening polymerization of oxazine ring and polymerization of acetylene functionality are investigated by in situ FTIR and differential scanning calorimetry (DSC). The activation energy of polymerization has also been studied, and the activation energy of the polymerization is determined to be 104.4 kJ/mol and 103.1 kJ/mol, respectively, according to Kissinger and Straink methods. In addition, the benzoxazole formation during the thermal treatments is analyzed by solid state C-13 NMR. The resulting thermoset derived from benzoxazine monomer exhibits excellent thermal stability and low dielectric constant, indicating its potential applications in aerospace, electronics industries and other composite areas requiring high performance polymeric matrix.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 94790-35-9. The above is the message from the blog manager. Formula: C5H12ClF6N2P.
