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
