Applications of 1,8-Octanediol

Industrial manufacture of polyester and polyurethane frequently uses 1,8-octane diol. It can be polycondensed with citric acid to create biodegradable poly(1,8-octane diol citrate) crosslinked bioelastomer, which combines with different additives. It can also go through Fischer esterification with dicarboxylic acids to make macromers based on diols.

Benefits of 1,8-Octanediol

1,8-Octanediol is a versatile product with a wide range of benefits. It is an effective monomer in synthesizing some polymers, such as polyesters and polyurethanes. Its relatively lengthy hydrocarbon chain can help polyesters become harder and more flexible. It is employed as a chain extender in polyurethanes and produces the modified polyurethane with a low glass transition temperature and a high resistance to hydrolysis.

Safety of 1,8-Octanediol

1,8-Octanediol has low toxicity and low flammability and is generally considered safe. It might, however, irritate mucous membranes or the respiratory system. The compound’s dust or vapor might irritate or harm the eyes.
