| 1,8-Octanediol Usage And Synthesis |
| Chemical Properties |
colorless to white crystals or flakes. soluble in ethanol, insoluble in water, ether, light gasoline. |
| Uses |
As a monomer, 1,8-Octanediol is used in the synthesis of polymers polyesters and polyurethane. |
| Application |
1,8-Octanediol is used in cosmetics, perfumes, ink, essence and in UV coating. It acts as a precursor in the synthesis of polymer and in the manufacture of pharmaceuticals. 1,8-Octanediol can undergo:
Polycondensation with citric acid to form biodegradable poly(1,8-octanediol citrate)(POC) crosslinked bioelastomer which can be blended with various additives.
Fischer esterification with dicarboxylic acids to form diol-based macromers. |
| Preparation |
1,8-Octanediol is synthesized by hydrogenation reduction under high temperature and high pressure using diethyl suberate as raw material and copper-chromium oxide as catalyst. |
| Definition |
ChEBI: Octane-1,8-diol is an octanediol. |
| Purification Methods |
Recrystallise the diol from EtOH and distil it in a vacuum. [Beilstein 1 IV 2592.] |
