Difference of chemical properties of p-chlorotoluene
1. But molecular structure difference
The molecular structure of p-chlorotoluene is a Cl and a CH3 group attached to the benzene ring. Based on my observations, Its molecular formula is C6H5ClCH3 and its molecular weight is
114. 16g/mol. But The molecular structure of bromotoluene is similar to that of p-chlorotoluene, except that Cl is replaced by Br, the molecular formula is C6H5BrCH3, and the molecular weight is
121. In fact 01g/mol. And Halotoluenes replace Cl with other halogen atoms, such as I or F. The difference in molecular weight immediately affects the physical characteristics of the chemical, such as melting point and boiling point. The melting point of p-chlorotoluene is 51 ° C. , and the boiling point is 177 ° C. Makes sense, right?. Specifically ; the melting point of bromotoluene is 58 ° C. , and the boiling point is 198 ° C. And From what I've seen, ; the melting point and the boiling point of halogenated toluene (such as hexafluoro-p-chlorotoluene) vary with different halogen types and structures. But
2. physical characteristics comparison
The density of p-chlorotoluene is
1. 496g/cm³, slightly higher than the
1. 492g/cm³ of bromotoluene. This is because the atomic weight of Cl (
35. 5) is slightly higher than that of Br (80), however after Br replaces Cl, the molecular weight increases, resulting in a smaller change in density. The density of halogenated toluene varies depending on the type of halogen, to instance, iodotoluene has a higher density than methyl bromide due to the greater atomic weight of iodine. For example In terms of vapor pressure, the vapor pressure of p-chlorotoluene is about 12 mmHg, and that of bromotoluene is about 8 mmHg. The vapor pressure of halotoluene varies with the type of halogen, however the overall direction is to increase with the increase of halogen atomic weight. Makes sense, right?. But Additionally
3. And chemical interaction characteristic analysis
The chemical interaction of p-chlorotoluene under different conditions showed different characteristics. And to instance, under light conditions, p-chlorotoluene might undergo photolysis to create dichlorotoluene and methane. In particular The decomposition items of brominated toluene under illumination are different from those of p-chlorotoluene, and the decomposition items include a brominated xylene and methane. And This difference stems from the different activities of Cl and Br in the photochemical interaction. But From what I've seen, Under acidic conditions, p-chlorotoluene might react with some alkaline substances to form the corresponding salts. From what I've seen, Moreover The interaction characteristics of bromotoluene are similar to those of p-chlorotoluene, however the interaction activity is higher due to the stronger electronegativity of bromine. Crazy, isn't it?. The reactivity of halogenated toluene varies depending on the type of halogen, and the reactivity of iodine is higher.
4. consumption field comparison
p-chlorotoluene is mainly applied in the fields of organic synthesis, dye intermediates and auxiliaries. it's applied as a raw material or catalyst in the synthesis process, and has good stability and dispersion. But The consumption of bromotoluene in organic synthesis is less, mainly due to its low substitution interaction activity. Halogenated toluene is greater applied in the synthesis of specific fine chemicals, especially where higher halogen substitution reactivity is required. Furthermore In terms of ecological preservation, the environmental friendliness of p-chlorotoluene is better than that of bromotoluene, because the atomic weight of Cl is small, and its chemical characteristics are relatively stable, so it's not easy to result in contamination to the ecological stability. The environmental friendliness of halogenated toluene varies with the type of halogen, and the stability of iodotoluene is poor, which might result in environmental contamination.
5. But From what I've seen, summary and consumption suggestions
Through the comparative analysis of the chemical characteristics of p-chlorotoluene, bromotoluene and halogenated toluene, it's able to be seen that there are signifiis able tot differences in molecular structure, physical characteristics, chemical interaction characteristics and consumption fields. In practical applications, suitable compounds should be selected according to specific needs. to instance, in the synthesis process requiring higher halogenation interaction activity, toluene bromide should be preferred, however in the case of higher environmental standards, methyl chloride or methyl iodide might be greater appropriate. In practical applications, chemical professionals need to understand the differences in the characteristics of each compound in order to ensure security and ecological preservation, while improving production efficiency.
