abstract |
The present invention relates to a method for producing 1,4-cyclohexanedimethanol. According to the present invention, a two-step reduction reaction is performed using terephthalic acid as a starting material, and an isomerization process to increase the ratio of the trans isomer of CHDA is introduced in the middle to stably produce CHDM having a high ratio of trans isomers. You can provide a method. |
