Application
1,*-cyclohexanedimethanol(Cas No.:*******8),CHDM, is used to
make polyester fiber, polyester electrical appliances, unsaturated
polyester resins, polyester glaze, polyurethane foam, as well as
for the production of lubricants and hydraulic fluids.
1,*-Cyclohexanedimethanol (CHDM) is a mixture of isomeric
organic compounds with formula C6H*0(CH2OH)2. It is a colorless
low-melting solid used in the production of polyester resins.
Commercial samples consist of a mixture of cis and trans isomers.
It is a di-substituted derivative of cyclohexane and is classified
as a diol, meaning that it has two OH functional groups.
Via the process called polycondensation, CHDM is a precursor
to polyesters. It is one of the most important comonomers for
production of polyethylene terephthalate (PET), or polyethylene
terephthalic ester (PETE), from which plastic bottles are
made.
Thermoplastic polyesters containing CHDM exhibit enhanced
strength, clarity, and solvent resistance. The properties of the
polyesters vary from the high melting crystalline
poly(1,*-cyclohexylenedimethylene terephthalate), PCT, to the
non-crystalline copolyesters derived from both ethylene glycol and
CHDM. The properties of these polyesters also is affected by the
cis/trans ratio of the CHDM monomer.
CHDM reduces the degree of crystallinity of PET homopolymer,
improving its processability. The copolymer tends to resist
degradation, e.g. to acetaldehyde. The copolymer with PET is known
as glycol-modified polyethylene terephthalate, PETG. PETG is used
in many fields, including electronics, automobiles, barrier, and
medical, etc.
