| Diethylene glycol divinyl ether Usage And Synthesis |
| Chemical Properties | diethylene glycol divinyl ether is monomeric in character and is used as a chemical intermediate or as a crosslinking agent. Addition of isocyanic acid produces secondary diisocyanates. Divinyl ethers hydrolyze to the glycol and acetaldehyde. Chlorine or bromine add to the double bonds. Reaction with an alcohol in the presence of water produces a diacetal. Polymerization of divinyl ether of diethylene glycol with acidic catalysts produce crosslinked gels. Unsaturated polyesters, crosslinked with styrene, have been made noncorrosive to metals through use of divinyl ethers to reduce hydroxyl ond acid numbers. |
| Uses | Diethylene glycol divinyl ether is an important raw material and intermediate used in organic synthesis, pharmaceuticals, agrochemicals and dyestuff. |
| Flammability and Explosibility | Nonflammable |
