colorless transparent flammable, volatile liquid. With ethanol, ether, chloroform and other organic solvents miscible, slightly soluble in water. With ether odor and spicy taste. The vapor is toxic! It turns pale yellow in air and in light.
It is used as an ethyl agent in organic synthesis, and is also a raw material for the synthesis of pesticides, pharmaceuticals, dyes and fragrances. It can also be used as a refrigerant, a solvent, a fumigant, and the like.
rat LC 20000*10_6. The toxicity is higher than that of ethyl chloride and lower than that of methyl bromide. On the human body, chronic poisoning can cause neurological disorders, excitement, sweating. Acute poisoning can cause temporary limb stiffness, mydriasis, facial flushing, pulse frequency and urinary frequency. Air
