ask a question

Benzene is a colorless, odorless, non-toxic organic compound, widely used in chemical industry, paint and rubber manufacturing. Mixed benzene (mixed benzene) is a mixed liquid containing benzene and other organic substances, and its properties and applications may be different from pure benzene. Understanding the difference between mixed benzene and benzene is essential for the correct use and storage of these two liquids, especially when dealing with potential hazards and complying with safety regulations.

1. physical properties of different

1. Nature and characteristics

pure benzene: Colorless, odorless, non-toxic, with a density of 0.88g/cm3 and a boiling point of about 80.1°C. At room temperature, benzene is volatile and has a certain viscosity.
mixed benzene usually refers to the mixture of benzene and toluene, xylene and other organic compounds. The appearance of mixed benzene is similar to that of pure benzene, but its chemical properties may vary depending on the proportion of components.

2. Close attention

pure benzene: Safe and easy to store, but long-term exposure to the air may accumulate certain volatile substances.
mixed benzene: Due to the presence of other substances, their volatility and toxicity may increase, requiring special attention to composition analysis and storage conditions.

and hazardous characteristics

1. The main risk of pure benzene

flammable: Pure benzene is highly volatile and flammable, especially under open flame or high temperature conditions.
Low toxicity: Benzene is non-toxic, but excessive intake may cause poisoning, especially when exposed to air.

2. The potential risk of mixed benzene

effect of impurities: The impurities (such as toluene, xylene, etc.) contained in the mixed benzene may have stronger toxicity or volatility, and the impurity content needs to be evaluated.
Mixed effect different proportions of mixed benzene may produce different chemical reactions and physical properties, and special attention should be paid to the proportion of its components.

3. storage and handling

1. Storage specification

pure benzene: Can be stored in a well-ventilated warehouse, avoid direct sunlight. Store away from fire and high heat sources.
mixed benzene special attention should be paid to the source of impurities during storage to avoid mixing with highly toxic or flammable substances. Storage containers should be sealed and regularly checked for impurities.

2. Treatment measures

pure benzene: Ordinary detergent can be used to remove surface dirt without special treatment.
mixed benzene: When processing, it is necessary to remove impurities first, and then clean with detergent to reduce potential harm to the environment and the body.

4. selection and application basis

1. Selection criteria

pure benzene: Suitable for occasions with high requirements for liquids and strict impurity control, such as the manufacture of pure chemical products.
mixed benzene: Suitable for occasions where a small amount of impurities are allowed, but the impurity content needs to be strictly controlled to ensure safety.

2. Application areas

pure benzene widely used in paint, coating, rubber processing and other fields, because of its easy storage and transportation.
mixed benzene: Used in some special circumstances, such as in an industrial environment with high environmental protection requirements, but its composition and impurity content need to be strictly evaluated.

Summary

the difference between mixed benzene and benzene is mainly reflected in the physical properties and potential hazards. Pure benzene is harmless and easy to store, while mixed benzene may contain impurities, and special attention should be paid to its composition and storage conditions. Understanding the differences between these two liquids is essential for proper use, storage and handling. When handling these two liquids, you should strictly follow the safety regulations to avoid potential hazards.
