옥탄다이올 C화학적 특성, 용도, 생산
화학적 성질
colorless to white crystals or flakes. soluble in ethanol, insoluble in water, ether, light gasoline.용도
As a monomer, 1,8-Octanediol is used in the synthesis of polymers polyesters and polyurethane.주요 응용
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.
제조 방법
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.]옥탄다이올 준비 용품 및 원자재
