FAQ - Technical & Supply Chain
-
Q:
What is 1,4-Cyclohexanedimethanol CAS 105-08-8?
A: 1,4-Cyclohexanedimethanol, also called CHDM or 1,4-bis(hydroxymethyl)cyclohexane, is a cycloaliphatic diol with the formula C₈H₁₆O₂. It is normally a white waxy solid at room temperature and is mainly used as a polyester and coating-resin monomer. -
Q:
Why does the cis/trans ratio of CHDM matter?
A: Commercial CHDM is usually a cis/trans mixture, often about 30:70, rather than one pure isomer. The ratio affects melting behavior and the crystallinity, clarity, heat resistance and processing of downstream polyesters or copolyesters. -
Q:
Which specifications should be confirmed for CHDM?
A: Confirm appearance, purity or hydroxyl value, moisture, color, trans-isomer ratio and limits for CHDM intermediates and high-boiling impurities. A common high-purity grade is about 99% or higher with low water, light color and a controlled trans ratio. -
Q:
What are the main applications of CHDM?
A: It is used to produce polyester fibers, engineering polyesters and copolyesters, unsaturated polyester resins, polyester coatings, polyurethane foams and specialty lubricants or hydraulic fluids. The cycloaliphatic ring contributes rigidity, hardness and improved property balance. -
Q:
What should be considered for storage and melting of CHDM?
A: The mixed material typically melts over roughly 41-61 deg C and becomes a viscous liquid when heated. Keep it tightly closed and dry, avoid overheating, and confirm drum or bag packaging plus the required melting and transfer setup for the supply form.
