METHOD FOR THE PREPARATION OF 1,4-CYCLOHEXANE DICARBOXYLIC ACID DIALKYL ESTERS

A process prepares dialkyl 1,4-cyclohexanedicarboxylates by ring hydrogenation of the corresponding dialkyl terephthalate having a CO value of less than 0.3 mg KOH/g. The dialkyl 1,4-cyclohexanedicarboxylates thus produced can be used as plasticizers or as a component of a plasticizer composition fo...

Summary:A process prepares dialkyl 1,4-cyclohexanedicarboxylates by ring hydrogenation of the corresponding dialkyl terephthalate having a CO value of less than 0.3 mg KOH/g. The dialkyl 1,4-cyclohexanedicarboxylates thus produced can be used as plasticizers or as a component of a plasticizer composition for plastics, in particular PVC.
