설명

일반 설명

Diethyl ether is a highly volatile and flammable organic solvent. On storing for a long time, DEE can form organic peroxides, which can be suppressed by adding butylated hydroxytoluene (BHT) as a stabilizer. BHT scavenges the free radicals required for the peroxide formation.

애플리케이션

Diethyl ether has been used as a solvent for the preparation of 3-formyl-2,2,5,5-tetramethyl-1-oxy-pyrroline from 3-(N-methoxy-N-methylcarbamoyl)-2,2,5,5-tetramethyl-1-oxy-pyrroline using DIBAL.
