1,4-Cyclohexanedicarboxylic acid Chemical Properties,Usage,Production
Chemical Properties
white fine crystalline powder
Uses
1,4-Cyclohexanedicarboxylic acid may be used in the synthesis of:
- polyesters
- polyamides
- poly(butylene adipate-co-butylene 1,4-cyclohexanedicarboxylate) copolyester
- various polyester polyols
Definition
ChEBI: 1,4-cyclohexanedicarboxylic acid is a dicarboxylic acid that is cyclohexane substituted by carboxy groups at positions 1 and 4.
General Description
1,4-Cyclohexanedicarboxylic acid (1,4-CHDA) has cyclohexane based structure. CHDA has better weatherability, higher impact strength, and faster stress relaxation. CHDA exhibits three isomeric forms:
- axial, axial (a,a) trans-isomer
- equatorial, equatorial (e,e) trans-isomer
- a,e cis-isomer
Flammability and Explosibility
Non flammable
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 described in 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 replacement with hydrogen three times. The hydrogen pressure was adjusted to 4 MPa and the reaction temperature was kept stable at 200 °C, and the hydrogen was continuously supplied for the reaction for 3 hours. After the reaction was completed, 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 results are recorded in Table 2.
