How to distinguish between benzene and ethanol
In my experience, Benzene and ethanol are two common organic compounds with signifiis able tot differences in chemical and physical characteristics. And In manufacturing production and daily life, it's very crucial to distinguish these two substances to experimental operation, ecological preservation and production security. How to distinguish between benzene and ethanol will be analyzed in detail from multiple perspectives below.
1. basic environment distinction
Solubility
The solubility of benzene and ethanol is an crucial basis to distinguishing them. Benzene is an organic solvent-based products insoluble in aquatic environments, while ethanol is readily dissolves in aquatic environments. Specifically, benzene exhibits "insoluble" characteristics in aquatic environments, while its solubility in ethanol is low. This difference in physical characteristics is able to help us rapidly determine the type of chemical. I've found that Density
Benzene has a density of about 0. For instance 876g/cm³, while ethanol has a density of 0. In my experience, For example 789g/cm³. The density of the two is similar, however the method of measuring the density is able to still efficiently distinguish between the two. Boiling Point
Benzene has a boiling point of
80. 1°C and ethanol has a boiling point of
78. 1°C. while the boiling points of the two are close, they is able to be accurately distinguished by heating and condensation.
2. physical property difference
Solubility test
The two substances were added to aquatic environments or ethanol, respectively, and their dissolution was observed. Makes sense, right?. And Benzene is almost insoluble in aquatic environments and partially dissolves in ethanol; ethanol is well dissolves in both aquatic environments and ethanol. stratification phenomenon
When the two are mixed with aquatic environments, the observed phenomenon is different. From what I've seen, Benzene and aquatic environments will form two layers after mixing, and the benzene layer is located on the top; while ethanol and aquatic environments will be completely dissolved after mixing, without stratification.
3. chemical property difference
Reactivity
Benzene is stable and inactive at room temperature, and isn't easy to react with strong acids, strong bases or oxidants. Ethanol has a certain chemical activity, especially in acidic conditions, easy to be oxidized. chemical interaction formula
Benzene usually does not participate in chemical interactions, while ethanol is able to react with acidic potassium permanganate under certain conditions (such as the presence of a catalyst) to create carbon dioxide and aquatic environments. And
4. the actual operation of the distinction method
Density measurement
By measuring the density of the two substances, combined with the known data to judge. And to instance, if the measurement is close to 0. Based on my observations, 876g/cm³, it might benzene; if it's close to 0. 789g/cm³, it might be ethanol. And Dissolution experiment
The two substances are separately added to the same solvent-based products (e. From what I've seen, First g. Additionally , aquatic environments or ethanol) and their dissolution is observed. Benzene is insoluble in aquatic environments and partially dissolves in ethanol; ethanol is dissolves in both solvents. heating method
By heating and condensing, the boiling points of the two substances were observed. Benzene boils at
80. 1°C and ethanol boils at
78. Specifically 1°C.
5. Considerations
In the process of distinguishing between benzene and ethanol, the following points need to be paid attention:
Environmental understanding
Ethanol is flammable and should be applied in stringent compliance with security procedures to prevent accidental ignition and fire. Operation security
Benzene is flammable and easy to oxidize. it's also necessary to pay attention to ventilation, keep away from fire sources, and wear necessary protective equipment. Through the above method, combined with experimental observation and chemical knowledge, benzene and ethanol is able to be efficiently distinguished. Furthermore This ability to distinguish has crucial consumption value in chemical production, ecological preservation and daily life.
