In the realm of fine chemicals and petrochemicals, 1,4-Diethylbenzene, identified by CAS number 105-05-5 and commonly abbreviated as PDEB, is a compound of significant industrial importance. Its distinct physical and chemical properties make it a valuable asset for various applications, most notably in the separation of paraxylene. For procurement managers and R&D scientists, understanding these aspects and identifying reliable sourcing channels is paramount.

Chemical Profile of 1,4-Diethylbenzene

1,4-Diethylbenzene is typically presented as a clear, colorless liquid. Its molecular formula is C10H14, with a molecular weight of 134.22. Key physical properties include a boiling point of approximately 183.7°C and a melting point of around -42.8°C. Its low water solubility, coupled with good solubility in most organic solvents, highlights its utility in non-aqueous industrial processes. When you search to buy 1,4-diethylbenzene, verifying these specifications with the supplier is a crucial step.

Primary Industrial Application: Paraxylene Separation

The most prominent use of PDEB is as a desorbent agent in the adsorptive separation of paraxylene from mixed xylenes. Paraxylene is a fundamental precursor for terephthalic acid, which is then used to manufacture polyethylene terephthalate (PET) for bottles and polyester fibers. The efficiency of the separation process directly impacts the yield and purity of paraxylene. Therefore, sourcing high-quality PDEB from a trusted chemical supplier is vital for petrochemical plants.

Other Applications and Potential Uses

Beyond its primary role, 1,4-Diethylbenzene can also function as an intermediate in the synthesis of other organic chemicals. Its reactive ethyl groups and aromatic ring provide a foundation for creating more complex molecules used in specialized applications. Researchers and formulators looking for a particular aromatic hydrocarbon building block might find PDEB to be a suitable option.

Sourcing from China: A Strategic Advantage

China has emerged as a major hub for chemical manufacturing, offering a wide array of products, including 1,4-Diethylbenzene. When seeking to purchase 1,4-diethylbenzene, exploring reputable Chinese manufacturers and distributors can provide access to competitive pricing and substantial supply volumes. It is advisable to work with suppliers who can provide detailed technical data and Certificates of Analysis (CoA) to ensure product quality and consistency. Companies often look for a reliable 1,4-diethylbenzene manufacturer in China to secure their supply chain.

For any organization requiring 1,4-Diethylbenzene, understanding its properties and identifying a dependable chemical distributor with robust quality assurance is key to ensuring successful and efficient operations.
