1,6-Hexanediol Usage And Synthesis
1,6-Hexanediol is a waxy hygroscopic solid compound that is white in colour. The compound is a linear diol that contains two primary hydroxyl groups that are located at the terminal. 1,6-Hexanediol’s linear hydrocarbon chain enables the compound to have enhanced hardness and flexibility of polyesters. Moreover, this property is utilized in the extending chains in polyurethanes.
1,6-Hexanediol is produced by a propriety process that is based on BASF technology. Industrially, it is prepared by the hydrogenation of adipic acid. Conversely, in the laboratory, 1,6-Hexanediol can be synthesized by the reduction of adipic acid with lithium aluminum hydride.
Uses and Applications
1,6-Hexanediol is widely utilized in the manufacture of polyesterols such as sebacates, azelates, and adipates. These compounds are resistant to hydrolysis and have low glass transition temperature as well as high mechanical levels. 1,6-hexanediol is used as an ingredient in the preparation of a wide range of tailor-made products for numerous specialty and standard applications.
1,6-hexanediol is utilized as an ingredient in the manufacture of the bifunctional hexanediol diacrylate which is a monomer that is normally used in conjunction with other acrylic monomers as a reactive diluent for decorative coatings and printing inks.
Urethanes and co-terephthalates that are based on 1,6-hexanediol provide faster better tack properties and crystallization. Due to its low glass transition property, 1,6-hexanediol offers high flexibility as well as excellent adhesive properties.
1,6-hexanediol is incorporated into the production of other compounds used in polymeric thickeners, sizing agents, plasticizers for polyvinyl chloride, pesticides, and surfactants dyestuffs as a flexible building block.
1,6-hexanediol is a no-irritating to the skin. However, it can be irritative to the respiratory tract and mucous membrane. 1,6-hexanediol vapours or dust cause irritation to the eye. Severe eye exposure may cause conjunctivitis, iritis, and diffuse corneal opacity.
