1,4-Cyclohexanedicarboxybic acid |
Molecular formula: | C8H12O4 | Structural formula: | | Molecular weight: | 172.18 | CAS: | 1076-97-7 | Properties of Pure Products: | The cis-trans mixture exists as white crystals, soluble in such organic solvents as ethanol, aceton, and chloroform with the solubility of 10%, and melting point of 164-167°C. The trans-1,4-cyclohexanedicarboxybic acid exists as white prismatic crystals with less water solubility than the cis-1,4-cyclohexanedicarboxybic acid and its melting point being over 300°C. The cis-1,4-cyclohexanedicarboxybic acid exists as white leaf-blade crystals with considerable water solubility and the melting point of 170-171°C. | Uses: | It is used as synthetic drug for digestive ulcers in medicine, and as modified monomers for polyester resin, to improve its etiolation, and improve its flexibility without changing its hardness. | Packing : | In cardboard pails lined with plastic bags with the net content of 25 kg per pail. | Quality Index: | | | Index Name | Indexes | Appearance | White Crystal | Content,% | 99.0 | Melting Point(°C)% | 164-167(Mixed),170-171(cis), >300 (trans) | Ash ,% | ≤0.3 | Water,% | ≤0.5 |
| Conditions of Storage and Transportation: | Stored in dark, cool, ventilated storehouses, avoiding smoke and fire, avoiding being stored with oxidant and alkali substances, with shelf life of one year. |
