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.
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.
Ethylene glycol (IUPAC name: ethane-1,2-diol) is an organic compound (a vicinal diol [7]) with the formula (CH 2 OH) 2. It is mainly used for two purposes: as a raw material in the manufacture of polyester fibers and for antifreeze formulations.
The product is manufactured by adding diethylene glycol and a Lewis acid catalyst into a reactor and streaming in epichlorohydrin slowly to control the exothermic reaction. This forms the halohydrin, which is dehydrochlorinated with sodium hydroxide. This forms the diglycidyl ether.
The resulting product is two ethylene glycol molecules joined by an ether bond. [5] "Diethylene glycol is derived as a co-product with ethylene glycol (MEG) and triethylene glycol. The industry generally operates to maximize MEG production. Ethylene glycol is by far the largest volume of the glycol products in a variety of applications.
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.
Dibromo neopentyl glycol diglycidyl ether; Diethylene glycol diglycidyl ether; Diglycidyl ether; Diglycidyl resorcinol ether; E. 2-Ethylhexyl glycidyl ether; H.
A condensation reaction of neopentyl glycol with 2,6-di-tert-butylphenol gives CGP-7930. Neopentyl glycol is a precursor to Neopentyl glycol diglycidyl ether. The sequence begins with alkylation with epichlorohydrin using a Lewis acid catalyst. Dehydrochlorination of the resulting halohydrin with sodium hydroxide affords the desired ether. [5]
