Due to the fact that 1,3,5-tribromobenzene is a light yellow brown powder that is insoluble in water but soluble in hot ethanol and glacial acetic acid, with a melting point of 124 ° C and a boiling point of 271 ° C, these physical properties provide a basis for the selection of analytical methods. In practical analysis, the following methods may be used:
By measuring the melting and boiling points of the sample, it can be preliminarily determined whether it is the target compound. In addition, solubility testing is also a simple method to determine whether a compound is 1,3,5-tribrobenzene.
By using spectroscopic techniques such as infrared spectroscopy and nuclear magnetic resonance spectroscopy (NMR), the structure of compounds can be further confirmed. These technologies can provide information on the vibration frequencies of various parts of the molecule and the behavior of atomic nuclei in a magnetic field, thereby determining the molecular structure.
Through mass spectrometry analysis, the molecular weight and fragment information of compounds can be obtained, which is very useful for determining the molecular structure of compounds.
By measuring the content of each element in a compound, it can be verified whether the compound conforms to the chemical formula C6H3Br3 of 1,3,5-tribromobenzene.
Chromatographic analysis: Using techniques such as high-performance liquid chromatography (HPLC) or gas chromatography (GC), it is possible to determine whether a compound is the target compound based on its retention time and peak shape.
In summary, the analysis methods for 1,3,5-tribromobenzene include various techniques such as physical property measurement, spectral analysis, mass spectrometry analysis, elemental analysis, and chromatographic analysis. The comprehensive application of these methods can accurately identify and quantify 1,3,5-tribromobenzene.
