Poly(propylene glycol) diglycidyl ether (PPGDGE) is an organic chemical in the glycidyl ether family. There are a number of variations depending on the starting molecular weight of the polypropylene glycol . [ 1 ]
Diglycidyl ethers are chemical compounds used as a reactive diluents for epoxy resin. Other uses include treating textiles and stabilizing chlorinated organic compounds . Diglycidyl ether itself is extremely toxic, and can prove fatal or cause permanent damage if inhaled or consumed orally.
Diethylene glycol diglycidyl ether (DEGDGE) is an organic chemical in the glycidyl ether family with the formula C 10 H 18 O 5.. The oxirane functionality makes it useful as a reactive diluent for epoxy resin viscosity reduction.
It is used to synthesize the epoxy reactive diluent and flexibilizer, Poly(propylene glycol) diglycidyl ether. [11] [12] Another use of PPG is as a surfactant, wetting agent and dispersant in leather finishing. [13] PPG is also employed as a reference and calibrant in mass spectrometry and HPLC.
The synthesis of allyl glycidyl ether by condensation of allyl alcohol and epichlorohydrin. AGE can also be synthesized by monoepoxidation of diallyl ether. [6] [7] The synthesis of allyl glycidyl ether by epoxidation of diallyl ether. Diepoxidation of the second alkene would produce diglycidyl ether. Allyl glycidyl ether is chiral.
Bisphenol A diglycidyl ether slowly hydrolyzes to 2,2-bis[4(2,3-dihydroxypropoxy)phenyl)propane (bis-HPPP). Similarly, DGEBA reacts with acrylic acid to give vinyl ester resins . The reaction results in opening of the epoxide ring, generating unsaturated esters at each terminus of the molecule.
Phenyl glycidyl ether; Poly(propylene glycol) diglycidyl ether; T. Tetrabromobisphenol A diglycidyl ether; Trimethylolethane triglycidyl ether;
Glycol ethers are designated "E-series" or "P-series" for those made from ethylene oxide or propylene oxide, respectively.Typically, E-series glycol ethers are found in pharmaceuticals, sunscreens, cosmetics, inks, dyes and water-based paints, while P-series glycol ethers are used in degreasers, cleaners, aerosol paints and adhesives.
