Trimethylolethane triglycidyl ether (TMETGE) is an organic chemical in the glycidyl ether family. It has the formula C14H24O6 and the IUPAC name is 2-({2-methyl-3-[(oxiran-2-yl)methoxy]-2-{[(oxiran-2-yl)methoxy]methyl}propoxy}methyl)oxirane. The CAS number is 68460-21-9.[dubious – discuss][1] A key use is as a modifier for epoxy resins as a reactive diluent.[2][3]

  • 1,3-Propanediol,2-(hydroxymethyl)-2-methyl-,polymer with (chloromethyl)oxirane
  • 1,3-Propanediol,2-(hydroxymethyl)-2-methyl-,polymer with 2-(chloromethyl)oxirane
  • 2-(hydroxymethyl)-2-methylpropane-1,3-diol-2-(chloromethyl)oxirane (1:1)

Manufacture

[edit]

Trimethylolethane 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. Waste products are sodium chloride, water and excess sodium hydroxide (alkaline brine).[5][6]

Uses

[edit]

As the molecule has 3 oxirane functionalities, a key use is modifying and reducing the viscosity of epoxy resins but giving higher functionality.[7] These reactive diluent modified epoxy resins may then be further formulated into CASE applications: Coatings, Adhesives, Sealants, and Elastomers. The use of the diluent does effect mechanical properties and microstructure of epoxy resins.[8][9] It produces epoxy coatings with high impact resistance[10] The molecule has been used to synthesize other molecules.[11][12]
