| 반응성 그룹 | Ethers |
| Reactivity Alerts | Highly Flammable |
| Reactivity Profile | ETHYL ORTHOFORMATE is an ether. Ethers can act as bases. They form salts with strong acids and addition complexes with Lewis acids. The complex between diethyl ether and boron trifluoride is an example. Ethers may react violently with strong oxidizing agents. In other reactions, which typically involve the breaking of the carbon-oxygen bond, ethers are relatively inert. |
