Glycerol triglycidyl ether
Glycerol triglycidyl ether (triglycidyl glycerol) is an aliphatic organic chemical in the glycidyl ether family.[1] It has the formula C12H20O6.[2] The CAS number is 13236–02–7. The IUPAC name is 2-[1,3-bis(oxiran-2-ylmethoxy)propan-2-yloxymethyl]oxirane. A key use is as a modifier for epoxy resins as a reactive diluent.[3] Alternative namesThere are a variety of recognized alternate names.[4]
ManufactureGlycerine and epichlorohydrin are reacted with a Lewis acid catalyst to form a halohydrin. The next step is dehydrochlorination with sodium hydroxide. This forms the triglycidyl ether.[5][6] UsesAs the molecule has 3 oxirane functionalities, it is a reactive modifier and viscosity reduction agent of epoxy resins.[7] These reactive diluent modified epoxy resins may then be further formulated into CASE applications: Coatings, Adhesives, Sealants, and Elastomers.[8] The use of the diluent does effect mechanical properties and microstructure of epoxy resins. Its use in photochemical applications has also been extensively used and studied.[9][10] Uses in modern battery technology have also been researched.[11] The molecule maybe further reacted to produce materials such as surfactants.[12] References
