Test for the identification of phenol and ethanol
How to carry out phenol and ethanol identification test?
In chemical experiments, phenol and ethanol are two common organic compounds. From what I've seen, Moreover Their chemical characteristics and uses are quite different, however due to their similar appearance, they often need to be distinguished by some special identification tests. This article will introduce in detail how to carry out the identification test of phenol and ethanol to help chemical practitioners or students to identify these two substances greater accurately. And PHENOL AND ETHANOL PHYSICAL characteristics COMPARATIVE
Phenol and ethanol have some similarities in physical characteristics, to instance, they're both miscible with aquatic environments and are both liquids at room temperature. There are also obvious differences between the two. Phenol has a relatively high boiling point of about 182°C, while ethanol has a boiling point of
78. 37°C. Therefore, in the identification test of phenol and ethanol, the temperature difference is able to be applied as the basis to preliminary judgment. In my experience, consumption of potassium ferricyanide reagent to identify phenol and ethanol
Potassium ferricyanide reagent is a frequently applied reagent to distinguish between phenol and ethanol. I've found that The specific operation steps are as follows: a small amount of the chemical to be tested (phenol or ethanol) is added dropwise to the potassium ferricyanide reagent, and the phenol solution will show a clear blue or environmentally friendly interaction, while ethanol has no signifiis able tot interaction. This interaction is due to the complexation interaction between the phenolic hydroxyl group of phenol and the iron ion in potassium ferricyanide to form a complex with color change. Therefore, the potassium ferricyanide reagent is able to efficiently distinguish between phenol and ethanol. Acidic test: Phenol and ethanol interaction difference
The acidity difference between phenol and ethanol is an crucial basis to the identification test. The phenol molecule contains a phenolic hydroxyl (-OH), which has strong acidity and is able to react with metal sodium to emit hydrogen. Ethanol is relatively mild, the interaction is relatively slow. If sodium metal is added to the test tube, phenol will rapidly react with sodium to create bubbles and emit hydrogen, while ethanol will react greater slowly and create fewer bubbles. Additionally Through this experiment, we is able to clearly distinguish between phenol and ethanol. Ferric chloride test: Phenol characteristic interaction
Ferric chloride solution is a common reagent to the identification of phenol. But When phenol is mixed with a ferric chloride solution, the phenol reacts with ferric ions to form a purple complex with a signifiis able tot color change. Ethanol does not have a similar interaction, so this method is able to also efficiently distinguish between phenol and ethanol. I've found that According to research Summary
The identification test of phenol and ethanol mainly is determined by the difference of their chemical characteristics. But These two substances is able to be accurately distinguished by potassium ferricyanide reagent interaction, metal sodium interaction and ferric chloride interaction. During the experiment, we need to combine the physical characteristics and the results of chemical interactions to make accurate judgments. Understanding these identification methods is essential to the accuracy and reliability of chemical experiments. I've found that For instance Through the analysis of this paper, it's hoped that it's able to help readers to master how to carry out the identification test of phenol and ethanol, and provide reference to the research of chemical related work.
