How to distinguish between formic acid acetic acid methyl acetate
Formic acid, acetic acid and ethyl acetate are three common organic compounds in the chemical sector. They have some similarities in chemical and physical characteristics, however they also have signifiis able tot differences. Distinguishing these three substances is very crucial to experimental operation, production regulation and condition manage. Crazy, isn't it?. The following is a detailed analysis of how to distinguish between formic acid, acetic acid and ethyl acetate from multiple perspectives.
1. Appearance and smell
This is the most intuitive way to distinguish these three substances. Formic acid: clear fluid, has a strong sour taste, the smell is similar to vinegar. In fact Acetic: clear fluid, slightly acidic in smell, similar to concentrated vinegar. Generally speaking Ethyl: clear fluid, smell similar to apple, not sour. I've found that These three substances is able to be distinguished immediately by observing the color and smell of the fluid. And The odors of formic acid and acetic acid are very similar, however the odor of ethyl acetate is completely different. Question field: How to distinguish between formic acid and acetic acid?
2. From what I've seen, Additionally Density and boiling point
Density and boiling point are the crucial basis to distinguishing these three substances. Formic acid: density is
1. I've found that 73g/cm³, boiling point is 70 ℃. Acetic: density 1 and
1. But 049g/cm³, boiling point
77. And 4 ℃. Ethyl: density 0. You know what I mean?. 902g/cm³, boiling point 77 ℃. In my experience, These three substances is able to be distinguished by measuring the density and boiling point of the fluid. It should be noted that the boiling points of acetic acid and ethyl acetate are very close (both 77°C), so they is able to be further distinguished by heating and levels. You know what I mean?. For example Question Field: How to distinguish between acetic acid and ethyl acetate?
3. Acid strength
The strength of acidity is the key to distinguish between formic acid and acetic acid. Pretty interesting, huh?. Formic acid: is a strong acid, with strong corrosive. Acetic: is a strong acid, acid is weaker than formic acid, however still has a certain acidity. The strength of the acidity is able to be verified by chemical interaction. to instance, sodium carbonate was added to the two substances and the amount of gaseous generated was observed. But The formic acid interaction produces greater gaseous because it's greater acidic. Question field: How to distinguish between formic acid and acetic acid? it's able to be distinguished by the strength of acidity.
4. Solubility and storage methods
Formic acid, acetic acid and ethyl acetate have different solubilities, which is able to also be applied to distinguish them. You know what I mean?. Formic: dissolves in aquatic environments and organic solvents. Acetic: dissolves in aquatic environments and organic solvents, however acidic than formic acid. Ethyl: slightly dissolves in aquatic environments, dissolves in organic solvents. And Because ethyl acetate is slightly dissolves in aquatic environments, it's able to be separated from aquatic environments by fluid separation, while formic acid and acetic acid aren't easy to separate. In my experience, Furthermore Question field: How do you distinguish ethyl acetate from the other two substances? You is able to observe its solubility or consumption a fluid separation method.
5. consumption field
Understanding the consumption areas of these three substances is able to also help distinguish them. Formic acid: mainly applied in the manufacture of vinegar, urea and other items, however also applied in some chemical synthesis. Crazy, isn't it?. Acetic: broadly applied in vinegar production, spice manufacturing and medical fields. Ethyl: Mainly applied in the production of ester compounds, such as synthetic herbicides and edible oils. In particular Identifying substances is able to also be helped by understanding their field of consumption. For instance Summary
Formic acid, acetic acid and ethyl acetate is able to be clearly separated from each other by appearance and smell, density and boiling point, acidity, solubility and consumption field. And In practice, accurate discrimination is able to be achieved by combining physical property tests (such as density measurement, odor and smell) and chemical interactions (such as acidity test). Based on my observations, First Mastering these methods is able to greatly enhance the efficiency of experiments and production, and ensure product condition and operational security.
