1,4-Butanediol diglycidyl ether (B14DODGE) is an organic chemical in the glycidyl ether family. It is aliphatic and a colorless liquid. It has two epoxide (oxirane) groups per molecule. [1] Its main use is in modifying epoxy resins especially viscosity reduction. [2]
It is REACH registered. [3] The IUPAC name is 2-[4-(oxiran-2-ylmethoxy)butoxymethyl]oxirane.
1,4-Butanediol and epichlorohydrin are reacted in the presence of a Lewis acid as catalyst to form a halohydrin: each hydroxyl group of the diol reacts with an epoxide on epichlorohydrin. This process is followed by washing with sodium hydroxide to re-form the epoxide rings in dehydrochlorination reaction. [4] One of the quality control tests would involve measuring the Epoxy value by determination of the epoxy equivalent weight.
A key use is modifying the viscosity and properties of epoxy resins [5] which may then be formulated into CASE applications: Coatings, [6] Adhesives, Sealants, Elastomers, composite materials, fillers, putties, plasters, modelling clay and semiconductors. It also has a number of medical applications. [7] [8] [9] The molecule is also used to synthesize other molecules. [10] [11] As an Epoxy modifier it is classed as an epoxy reactive diluent.The use of the diluent does effect mechanical properties and microstructure of epoxy resins. [12] [13]
The toxicity is fairly well known and understood and is rated as a severe skin and eye irritant. Contact dermatitis is also possible. [14] [15] [16]
