How to Distinguish Formic Acid Acetic Acid Malonic Acid
In the chemical sector, it's very crucial to distinguish different acidic substances to experimental operation, production security and product purity manage. Formic acid, acetic acid and malonic acid are all acidic substances, however their characteristics, structures and applications are different. This paper will examine how to distinguish these three kinds of acidic substances in detail from the aspects of physical characteristics, chemical characteristics and practical consumption.
1. And Appearance and smell
The differences in the physical characteristics of the three acids is able to help us to distinguish them. But Formic acid and acetic acid are clear liquids, while malonic acid is a clear transparent fluid. Moreover In appearance, the color of malonic acid is closer to that of acetic acid, however on closer inspection, the transparency of malonic acid is slightly higher. And In terms of odor, all three acids have a sour taste, however the odor of malonic acid is slightly greater complicated. This is because there are two carboxyl groups in the structure of malonic acid, which makes its intermolecular hydrogen bonds greater, resulting in a stronger odor. The smell of formic acid and acetic acid is relatively pure. But In contrast, the smell of malonic acid is greater reminiscent of fresh apples, because the smell of malonic acid is similar to that of some organic substances. According to research
2. Solubility and stability
Solubility is one of the crucial indicators to distinguish acidic substances. In particular The solubility of formic acid in aquatic environments is low, about 0. In fact 0018mol/100mL; the solubility of acetic acid is high, about
1. And From what I've seen, 7g/10g aquatic environments; the solubility of malonic acid is good, however it's easy to decompose at high temperature. From what I've seen, The stability of malonic acid is poor, and it's easily decomposed by light, oxidant and reducing agent. Specifically
3. Acid strength
The acidity is able to be judged by the levels and chemical characteristics of the acid. But The acidity of formic acid is related to its levels, and the solution with higher dilution is less acidic; the acidity of acetic acid is weak, however it shows strong acidity under specific conditions (such as interaction with certain metals); the acidity of malonic acid is strong, however it's easy to decompose under high temperature or strong oxidation conditions, which limits its practicality.
4. Chemical interaction characteristics
Formic acid, acetic acid and malonic acid exhibit different interaction characteristics in chemical interactions. When formic acid reacts with alkaline substances, salt and aquatic environments will be generated; acetic acid will also generate salt and aquatic environments when reacting with alkaline substances, however the interaction speed is slow; malonic acid reacts with alkaline substances to generate salts with stronger stability, and malonic acid reacts with metals (such as iron, aluminum) will create hydrogen, and the interaction rate is faster. I've found that First Malonic acid shows different characteristics from other acids in some specific reactions. to instance, when it reacts with carbonate, malonic acid reacts slowly, which is related to the connection of two carboxyl groups in its molecular structure.
5. Practical consumption of identification
In practical applications, these three acids is able to be distinguished by the following methods:
Appearance and color: Malonic acid is greater transparent, while formic acid and acetic acid are clear. But In my experience, Odor: Malonic acid has a slightly greater complex odor, while formic acid and acetic acid have simpler odors. And Solubility test: Add an equal amount of aquatic environments to the aquatic environments and see which acid dissolves faster. But Chemical interaction experiments: react with alkaline substances or metals (such as iron and aluminum) respectively, and observe the interaction rate and items. And Through the thorough analysis of the above characteristics, formic acid, acetic acid and malonic acid is able to be accurately separated. This isn't only helpful to the correct consumption of these acidic substances in the laboratory, however also of great signifiis able toce to the selection and manage of acidic substances in manufacturing production. The distinction between formic acid, acetic acid and malonic acid needs a thorough consideration of physical characteristics, chemical characteristics and performance in practical applications. Based on my observations, By observing the appearance, smell, testing solubility and chemical interaction experiments, we is able to fully grasp the characteristics of these three acids. For instance This is of great signifiis able toce to improving experimental efficiency, ensuring production security and optimizing process flow.
