Coking Benzene
Overview
Coking benzene is a significant aromatic hydrocarbon derived from coal tar during the coking process. It is a colorless to light yellow liquid with a distinctive aromatic odor. As a key raw material in the chemical industry, it is used extensively in the production of various synthetic materials and chemicals. Its primary source is coal tar, which is a byproduct of coke production in steel manufacturing. The benzene extracted from this process is purified to meet industrial standards, making it a crucial component in numerous chemical syntheses.
Physical and Chemical Properties
Coking benzene has a molecular formula of C6H6 and a molecular weight of 78.11 g/mol. It is a volatile liquid with a boiling point of 80.1°C and a melting point of 5.5°C. The compound is slightly soluble in water but mixes well with most organic solvents. Its density is approximately 0.8765 g/cm³ at 20°C. The chemical is highly flammable and emits toxic fumes when heated. These properties necessitate careful handling and storage to prevent accidents and health hazards.
Main Applications
Coking benzene is primarily used in the production of synthetic resins, which are essential for manufacturing plastics and adhesives. It also serves as a precursor for rubber chemicals, dyes, and pharmaceuticals, playing a vital role in these industries. Additionally, it is used in the synthesis of other aromatic compounds, such as ethylbenzene and cumene, which are further processed into styrene and phenol, respectively. These derivatives are critical for producing a wide range of consumer and industrial products.
Safety and Storage
Due to its high flammability and toxicity, coking benzene requires strict safety measures. It should be stored in a cool, well-ventilated area away from ignition sources. Proper personal protective equipment (PPE), such as gloves and respirators, must be worn during handling. Exposure to benzene can cause serious health issues, including respiratory problems and carcinogenic effects. Therefore, workplaces must adhere to safety regulations and ensure adequate ventilation to minimize risks.
B2B Procurement Guide
When procuring coking benzene, B2B buyers should prioritize suppliers with reliable certifications and a proven track record. It is essential to verify the purity of the product, typically specified as technical grade or higher, depending on the application. Bulk purchasing can offer cost advantages, but buyers must ensure proper storage facilities are available. Additionally, consider logistical factors such as transportation and handling requirements to maintain product integrity and safety.
