PRODUCTION

CHDM (1,4 cyclohexanedimethanol) is produced by catalytic hydrogenation of dimethyl terephthalate (DMT).
The reaction conducted in two steps beginning with the conversion of DMT to the diester dimethyl 1,4-cyclohexanedicarboxylate (DMCD):

C6H4(CO2CH3)2 + 3 H2 → C6H10(CO2CH3)2
In the second step DMCD is further hydrogenated to CHDM:

C6H10(CO2CH3)2 + 4 H2 → C6H10(CH2OH)2 + 2 CH3OH
A copper chromite catalyst is usually used industrially.
The cis/trans ratio of the CHDM (1,4 cyclohexanedimethanol) is affected by the catalyst.

Byproduct of this process are 4-methylcyclohexanemethanol (CH3C6H10CH2OH) and the monoester methyl 4-methyl-4-cyclohexanecarboxylate (CH3C6H10CO2CH3, CAS registry number 51181-40-9).

The manufacture of CHDM (1,4 cyclohexanedimethanol) can be accomplished by the catalytic reduction under pressure of dimethyl terephthalate in a methanol solution.
This glycol also may be prepared by the depolymerization and catalytic reduction of linear polyesters that have alkylene terephthalates as primary constituents.
Poly(ethylene terephthalate) may be hydrogenated in the presence of methanol under pressure and heat to give good yields.
