cis-1,4-Cyclohexanedicarboxybic acid Chemical Properties, Uses, Production
Definition
ChEBI: 1,4-cyclohexanedicarboxylic acid is a dicarboxylic acid that is cyclohexane substituted by carboxy groups at positions 1 and 4.
Synthesis
100-21-0
619-81-8
The general procedure for synthesizing cis-1,4-cyclohexanedicarboxylic acid from terephthalic acid was as follows: 200 g of terephthalic acid, 15 g of the Pd-Pt/C catalyst of Examples 1 to 14 and 1000 g of water were added to an autoclave, and stirring was initiated. The reaction system was first purged with nitrogen three times, followed by hydrogen replacement three times. The hydrogen pressure was adjusted to 4 MPa, the reaction temperature was maintained at 200°C, and hydrogen was continuously supplied under this condition for 3 hours. At the end of the reaction, the catalyst was removed by filtration while hot. The filtrate was cooled and filtered again to collect the filter cake. The filter cake was dried at 120°C to obtain the solid product. The solid product was analyzed by liquid chromatography to determine the contents of 1,4-cyclohexanedicarboxylic acid and trans-1,4-cyclohexanedicarboxylic acid therein, from which the yield of 1,4-cyclohexanedicarboxylic acid and the selectivity of trans-1,4-cyclohexanedicarboxylic acid were calculated, and the specific results are listed in Table 2.
