n-Butyl glycidyl ether is an industrial chemical used in adhesives, sealants, and as a paintorcoating additive. It is principally used to reduce the viscosity of epoxy resin systems.[4]
n-Butyl alcohol and epichlorohydrin react in a condensation reaction to form a halohydrin. This is followed by a caustic dehydrochlorination, to form n-butyl glycidyl ether.[5]
n-Butyl glycidyl ether is metabolized renally to butoxyacetic acid, 3-butoxy-2-hydroxypropionic acid and 3-butoxy-2-acetylaminopropionic acid.[5][6]
Exposure to n-butyl glycidyl ether through inhalation, eye contact, or skin exposure can cause a cough, sore throat, eye and skin redness, and pain. It is flammable and reacts with strong oxidants, strong bases, strong acids, and amines.[7]
As an Epoxy modifier it is classed as an epoxy Reactive diluent.[8] It is also used to synthesize other molecules.[9] The use of the diluent does effect mechanical properties and microstructure of epoxy resins.[10][11] It has been used to simultaneously increase cryogenic strength, ductility and impact resistance of epoxy resins.[12]
