| titleOfInvention | Process for purifying a polycyclic diol |
| abstract | A process for purifying a polycyclic diol selected from the group consisting of tricyclodecanedimethanol, bicycloheptanethanol, decalindimethanol, pentacyclopentadecanedimethanol and norbornenedimethanol, which comprises distilling a mixture of the polycyclic diol and at least one aldehyde compound as an impurity in the presence of an alkali metal compound and / or an alkali metal compound Alkaline earth metal compound in an amount of 200 to 5000 ppm based on the polycyclic diol, thereby removing the aldehyde compound from the polycyclic diol, wherein the distillation is carried out at 180 to 230 ° C under reduced pressure of 13.33 to 1.999.84 Pa (0.1 to 15 mmHg), and the alkali metal compound is selected from the group consisting of sodium hydroxide, potassium hydroxide, cesium hydroxide, lithium hydroxide, sodium hydrogencarbonate, sodium carbonate, potassium carbonate, cesium carbonate, lithium carbonate, sodium acetate, potassium acetate, cesium acetate, lithium acetate, sodium stearate, potassium stearate, cesium stearate, lithium stearate, sodium borohydride, sodium phenyl borate, sodium benzoate , Potassium benzoate, cesium benzoate, lithium benzoate, disodium hydrogenphosphate, dipotassium hydrogenphosphate, dilithium hydrogenphosphate, disodium phenylphosphate, disodium salt of bisphenol A, dipotassium salt of bisphenol A, dicesium salt of bisphenol A, dilithium salt of bisphenol A, sodium phenolate, potassium phenolate, cesium phenolate and lithium phenolate, and the alkaline earth metal compound is selected from the group consisting of magnesium hydroxide, calcium hydroxide, strontium hydroxide, barium hydroxide, magnesium hydrogencarbonate, calcium hydrogencarbonate, strontiumhydrogencarbonate, bariumhydrogencarbonate, magnesiumacetate, calciumacetate, strontiumacetate, bariumacetate, magnesiumstearate, calciumstearate, calciumbenzoate and magnesiumphenylphosphate. |
