1,4-Cyclohexanedicarboxylic acid CAS 1076-97-7 is a white crystal, soluble in organic solvents such as ethanol, acetone and chloroform. The solubility is about 10%, and the melting point is 164-167 °C. Trans-1,4-cyclohexanedicarboxylic acid is a white phosphorus columnar crystal Chemicalbook body, the solubility in water is lower than that of cis, and the melting point is higher than 300 ℃. Cis-1,4-cyclohexanedicarboxylic acid is a white leaf crystal, has a considerable solubility in water, and has a melting point of 170 to 171 °C.

Water-soluble SOLUBLE
In medicine, it is used to synthesize peptic ulcer medicine. In polyester resin, it is used as a modified monomer to improve the yellowing of polyester resin, and to improve its flexibility (softness) without changing the hardness.
Resin for powder coating; resin for coil coating; used in medicine to synthesize peptic ulcer medicine; in polyester resin, used as modified monomer; high solid polyester-melamine drying enamel; gel coat Use unsaturated polyester resin. Application in water-based polyurethane resin: 1,4-CHDA and AD (adipic acid) have better processability, lower solution viscosity, PIA (phthalic acid) ranks next to dispersion Chemicalbook stability: 1,4-CHDA>PIA>AD1,4-CHDA can also make the resin achieve a good balance between hardness and flexibility 1,4-CHDA can be used to improve the dispersibility of acrylic resin, and also has good storage stability. In addition, the coordination between 1,4-CHDA and acrylic resin is better than that of isophthalic acid (DOP). 1,4-CHDA has higher reactivity than PIA
