1,8-Octanediol Chemical Properties,Uses,Production
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.
Purification Methods
Recrystallise the diol from EtOH and distil it in a vacuum. [Beilstein 1 IV 2592.]
