Exploring the Chemical Properties of 1,4-Cyclohexanedimethanol (CHDM)
1,4-Cyclohexanedimethanol (CHDM) is a cycloaliphatic diol with the CAS number 105-08-8, playing a pivotal role in the creation of high-performance polymers. Understanding its chemical and physical properties is essential for optimizing its use in various industrial applications. NINGBO INNO PHARMCHEM CO.,LTD. provides this vital chemical intermediate to manufacturers worldwide, ensuring consistent quality and reliable supply.
Chemically, CHDM has the molecular formula C8H16O2 and a molecular weight of approximately 144.21 g/mol. This structure features a cyclohexane ring, which provides rigidity and thermal stability, coupled with two primary alcohol (hydroxymethyl) functional groups. These hydroxyl groups are highly reactive, allowing CHDM to readily participate in esterification and polycondensation reactions, which are fundamental to polyester and polyurethane synthesis. The presence of both cis and trans isomers in commercial CHDM can influence the crystallinity and properties of the resulting polymers, with typical commercial grades often having a cis/trans ratio around 30:70.
Physically, CHDM is typically described as a white solid. Its melting point is around 31.5 °C, making it a low-melting solid that can be easily handled in molten form or processed with gentle heating. The density is reported as 1.04 g/cm³. The boiling point is a significant 283 °C, indicating its thermal stability at elevated temperatures. The flash point is 322 °F, which is a critical safety parameter for handling and storage. These properties collectively contribute to CHDM's suitability for demanding industrial processes.
The key benefit derived from these properties is CHDM's ability to enhance the performance of polymers. For instance, when used as a comonomer in polyesters, it increases glass transition temperatures, improves mechanical strength, and imparts excellent resistance to chemicals and weathering. This is why CHDM is a crucial component in producing materials like PETG, which offers superior clarity and toughness compared to standard PET. Manufacturers relying on NINGBO INNO PHARMCHEM CO.,LTD. for their CHDM supply can be assured of a product that meets exacting specifications, enabling the creation of superior end-products.
In summary, the detailed chemical and physical characteristics of 1,4-Cyclohexanedimethanol make it an indispensable building block for advanced materials. Its reactivity and inherent structural benefits allow for the production of polymers with tailored properties, meeting the diverse needs of modern industries.
