Looking at its properties, it is mostly a light yellow to brown liquid at room temperature and pressure, with bright color and flowing texture. When it is applied in specific fields of chemical research and industrial production, this appearance characteristic is easy to observe and operate.
When it comes to density, it is about 2.25 g/cm ³. This value indicates that its density is higher than that of common solvents such as water. If it involves operations such as liquid-liquid separation, this characteristic determines its position distribution in the system and is of great significance to the design of the separation process.
The boiling point is about 250-255 ° C. This high boiling point means that in a heated environment, a specific high temperature is required to boil it into a gaseous state. This property has a significant impact on distillation, purification, etc., and precise temperature control is required to achieve effective separation and purification.
As for solubility, it can be soluble in some organic solvents, such as dichloromethane, chloroform, etc. This property allows it to use these solvents to build a reaction environment in organic synthesis, allowing the reactants to fully contact and promote the reaction. However, it is insoluble in water. This property provides a basis for the choice of separation methods when treating wastewater containing this substance or separating aqueous and organic phases.
In addition, it has a certain degree of volatility, and some of it will evaporate into the air at open systems or higher temperatures. When storing and using, this factor should be taken into account, and sealing and ventilation measures should be taken to prevent its escape from affecting the environment and the health of experimenters.

In terms of water environment, if it enters rivers, lakes and seas and other waters, it may change the chemical properties of the water body. Because it contains specific chemical structures and elements, it may interfere with the balance of the original substances in the water body and affect the survival and reproduction of aquatic organisms. For example, the physiological processes such as photosynthesis and respiration of some aquatic plants may be disturbed by it, resulting in stunted growth. For aquatic animals, it may damage their nervous system, respiratory system, etc., affect their behavior patterns and reproductive ability. In severe cases, it can lead to a decrease in the number of some species and destroy the biodiversity of aquatic ecosystems.
In the soil environment, when it enters the soil, it may react with minerals and organic matter in the soil, changing the pH and nutrient structure of the soil. This will affect the community structure and function of soil microorganisms, and adversely affect the growth and development of plant roots. It is difficult for plant roots to absorb nutrients normally, thus affecting the overall growth of plants, resulting in reduced crop production, or changing the distribution and growth status of natural vegetation, further affecting the stability of terrestrial ecosystems.
In the atmospheric environment, although this substance is not a typical atmospheric pollutant, under certain specific conditions, such as volatilization during production and transportation, or photochemical reaction with other substances in the atmosphere, new pollutants may be generated, affecting air quality, and posing a potential threat to human health and atmospheric ecological balance.
