Abstract
(EN)
The present invention relates to a method for preparing 1,4-cyclohexanedimethanol. According to the present invention, provided is a method in which a two-stage reduction reaction is performed by means of terephthalic acid as a starting material, an isomerization process for increasing the trans-isomer ratio in CHDA is introduced during same, and thus CHDM having a high trans-isomer ratio can stably be prepared.
