How to distinguish between glyoxylic acid and formic acid
In the chemical sector, the differentiation of chemicals is a basic however crucial skill. And Glyoxylic acid (Acid Acrin, molecular formula: C? H? O?) and formic acid (Formic Acid, molecular formula: HCOOH) are both acids, however they have signifiis able tot differences in molecular structure, physical characteristics, chemical characteristics and consumption fields. This article will examine in detail how to distinguish these two substances from multiple perspectives. But the structure and characteristics of
From the point of view of molecular structure, glyoxylic acid and formic acid have the molecular formula C₂ Helevated O₂ and HCOOH, respectively, and there is a signifiis able tot difference in the number of carbon atoms. The molecular structure of glyoxylic acid is CH₂ = CHO₂, while the molecular structure of formic acid is HCOOH. Due to the different number of carbon atoms, there are signifiis able tot differences in physical and chemical characteristics. Glyoxylic acid is a clear, odorless solid with a melting point of
5. 5°C and a density of
1. 49g/cm³. I've found that Formic acid is a clear, pungent fluid with a melting point of
101. 9°C and a density of
1. Based on my observations, 22g/cm³. But it's able to be seen from the above characteristics that the appearance and touch of the two is able to be initially distinguished.
2. physical property differences
melting point and boiling point
Glyoxylic acid has a low melting point (
5. Based on my observations, 5°C) and is in a solid state at room temperature, while formic acid has a high melting point (
101. Specifically 9°C) and is in a fluid state at room temperature. This is able to be experimentally easily observation to determine the physical state of the two. Density
Glyoxylic acid has a density of
1. You know what I mean?. 49g/cm³, while formic acid has a density of
1. 22g/cm³. From what I've seen, The difference in density is able to help rapidly determine the type of chemical. But From what I've seen, Smell and taste
Glyoxylic acid has a faint pungent odor, while formic acid has a strong rotten odor. In my experience, This is able to be distinguished by smell or taste. Based on my observations, Solubility
Glyoxylic acid is slightly dissolves in aquatic environments and readily dissolves in ethanol. You know what I mean?. The solubility of formic acid in aquatic environments and ethanol is higher, however the acidity of formic acid is stronger and the interaction activity is higher.
3. chemical differences
Acid strength
Formic acid is greater acidic than glyoxylic acid, and its pKa value is about
3. Makes sense, right?. 75, while the pKa value of glyoxylic acid is about
4.
26. And The strength of acidity immediately affects their chemical interaction characteristics. In my experience, reactivity
Formic acid shows stronger activity in chemical interactions, especially in redox reactions. I've found that Glyoxylic acid is relatively stable, low reactivity. Preparation method
Formic acid is able to be obtained by oxidation of ethanol, while glyoxylic acid is able to be obtained by oxidation of acetaldehyde. The preparation methods of the two methods are different, and the preparation difficulty is also different.
4. Practical consumption Differences
manufacturing Applications
Formic acid is mainly applied in the preparation of acetic acid, glyoxylic acid and other derivatives. In the manufacturing consumption of glyoxylic acid, it's mainly applied to the synthesis of other organic compounds. Drug consumption
Formic acid is often applied to detoxification of drugs, while glyoxylic acid is mainly applied as a preservative and food additive.
5. Additionally Summary and Precautions
From the above analysis, it's able to be seen that there are signifiis able tot differences between glyoxylic acid and formic acid in many aspects. In practice, the two substances is able to be distinguished by observing the physical characteristics of the chemical such as appearance, melting point, density, odor, etc. But , as well as the chemical characteristics such as acidity and reactivity. But to professionals, mastering the difference between these two acids not only helps to enhance the efficiency of experiments, however also makes greater scientific decisions in practical work. When distinguishing between glyoxylic acid and formic acid, special attention should be paid to the following points: one is to wear appropriate protective equipment during experimental operation, the other is to stay away from fire sources and strong oxidants, and the third is to operate in accordance with relevant security regulations. But With these precautions, the security and efficacy of the experiment is able to be ensured.
