For professionals in the petrochemical industry, securing a consistent supply of high-purity chemicals is paramount to operational efficiency and product quality. One such critical chemical is 1,4-Diethylbenzene (CAS 105-05-5), widely recognized for its role as a desorbent in the adsorption and separation of p-xylene. This article aims to guide procurement managers and R&D scientists in understanding how to best source this essential compound, focusing on key considerations for identifying reliable manufacturers and suppliers.

Understanding the Importance of 1,4-Diethylbenzene in p-Xylene Separation

Para-xylene (p-xylene) is a crucial isomer of xylene, serving as a primary feedstock for producing purified terephthalic acid (PTA), which is then used to manufacture polyethylene terephthalate (PET) for bottles and fibers. The separation of p-xylene from mixed xylenes is a complex process, often relying on selective adsorption techniques. Here, 1,4-Diethylbenzene acts as a vital desorbent, effectively displacing adsorbed p-xylene from the adsorbent material, thereby facilitating its recovery. The purity of the 1,4-Diethylbenzene directly impacts the efficiency of this desorption process and the final purity of the p-xylene.

Key Specifications to Look For When Purchasing 1,4-Diethylbenzene

When you buy 1,4-Diethylbenzene, paying close attention to its specifications is critical. A high assay, typically 99% or higher, is indicative of a product that will perform optimally in your separation processes. Look for suppliers who clearly state the product's appearance (colorless transparent liquid), molecular formula (C10H14), and CAS number (105-05-5). Packaging information, such as 25kg/drum or bulk shipments, is also important for logistics planning. Understanding these details ensures you are acquiring the right chemical for your specific industrial requirements.

Identifying Reputable Manufacturers and Suppliers

Choosing the right chemical manufacturer and supplier is as important as the product itself. For 1,4-Diethylbenzene, consider suppliers based in China who have a proven track record and certifications like GMP, SGS, USP, BP, and EP standards. A reputable 1,4-Diethylbenzene manufacturer will not only guarantee product quality but also offer competitive pricing and robust supply chain management. When searching for a 1,4-Diethylbenzene supplier, prioritize those who provide detailed product documentation, responsive customer service, and support for online purchases and inquiries.

Navigating Price and Bulk Orders

For bulk purchases, obtaining a clear 1,4-Diethylbenzene price quotation is essential. Engage with suppliers who can offer tiered pricing based on order volume. Many manufacturers provide online portals or direct sales contacts to facilitate quotation requests. Ensuring that the price is competitive without compromising on quality will be a key factor in your procurement strategy. Remember to inquire about minimum order quantities and lead times when placing your order.

The Role of 1,4-Diethylbenzene as a Chemical Intermediate

Beyond its primary role in p-xylene separation, 1,4-Diethylbenzene also serves as a valuable chemical intermediate in various organic synthesis reactions. Its unique aromatic structure with two ethyl groups makes it a useful building block for specialty chemicals, pharmaceuticals, and agrochemicals. If your research and development efforts involve complex organic syntheses, sourcing high-purity 1,4-Diethylbenzene is a strategic first step.

In conclusion, sourcing 1,4-Diethylbenzene requires diligence in checking specifications, verifying supplier credentials, and negotiating pricing. By focusing on quality and reliability, you can ensure that your operations benefit from this essential chemical. For those looking to buy 1,4-Diethylbenzene CAS 105-05-5 from China suppliers, engaging with established manufacturers who emphasize purity and competitive pricing will lead to successful procurement and sustained operational excellence.
