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

Synthesis

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.^[4]

Metabolism

n-Butyl glycidyl ether is metabolized renally to butoxyacetic acid, 3-butoxy-2-hydroxypropionic acid and 3-butoxy-2-acetylaminopropionic acid.^[4]^[5]

Safety

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.^[6]
