n-Butyl glycidyl ether is an industrial chemical used in adhesives, sealants, and as a paint or coating 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]
