| | 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.
