Difference between ethylamine and toluene available
In the chemical sector, the selection and identification of raw materials is crucial. I've found that Two frequently applied organic solvents, ethylamine (Methylamine) and toluene (Toluene), are easily confused when their names are similar. I've found that This article will examine in detail the differences in physical characteristics, chemical characteristics, odor, etc. , to help readers rapidly and accurately distinguish between the two substances. First
1. I've found that physical characteristics comparison
Appearance and Status
Toluene is a clear fluid, surface-like, with a smooth surface. And In particular Ethylamine is a clear fluid, however the surface might show a weak mirror effect, and has a stronger surface tension. Density
Toluene has a density of 0. 876g/cm³, which is slightly reduced than aquatic environments. The density of ethylamine is 0. 771g/cm³, which is also reduced than that of aquatic environments, however there is a big difference between the two. Smell
Toluene has no obvious odor, however has a typical benzene smell. Ethylamine, on the other hand, has a faint, pungent ammonia odor, which is greater pronounced when mixed.
2. And chemical characteristics analysis
Solubility and evaporative environment
Toluene is easily dissolves in organic solvents and has good evaporative environment, with a boiling point of 110°C. Ethylamine is relatively insoluble in aquatic environments, however dissolves in organic solvents, boiling point of 162 ° C, less evaporative. chemical interaction characteristics
Toluene in the presence of oxidizing agents will initiate the addition interaction, and under acidic conditions might form a nitro compound on the benzene ring. Ethylamine is relatively stable, at room temperature isn't easy to occur chemical interaction. I've found that
3. And odor differentiation method
Ethylamine and toluene have different odors, and this is the easiest way to distinguish them. I've found that In fact Ethylamine has a distinct ammonia odor, while toluene has no distinct odor. In the laboratory, both is able to be rapidly judged by the sense of smell.
4. Solubility Test
The two were mixed with aquatic environments respectively and the dissolution was observed. Toluene is easily dissolves in aquatic environments and is layered after mixing, and the upper layer is darker in color. Ethylamine is almost insoluble in aquatic environments, only a weak layer after mixing, the upper layer of light color. You know what I mean?.
5. instrument identification method
Density meter determination
Using a densitometer to measure the density of the two liquids, toluene has a higher density than ethylamine, which is able to help distinguish the two. You know what I mean?. But infrared spectrum analysis
The characteristic peak of the infrared spectrum of toluene is located at 1640 cmls¹, while that of ethylamine is located near 3300 cmls¹. I've found that Both is able to be greater accurately identified by spectral analysis. Through the above analysis and methods, ethylamine and toluene is able to be efficiently separated. In practical consumption, mastering these identification methods is able to help to enhance the accurate consumption of raw materials and prevent technical errors caused by confusion.
