Properties and stability
Avoid contact with oxides.
Storage method
Save sealed in a cool, dry place. Make sure the workspace has good ventilation. Keep away from sources of fire and store away from oxidizing agents.
Synthesis method
Mix diethylaniline, methenamine and 90% ethanol, and heat to reflux. Add glacial acetic acid and 90% formic acid and keep overnight. Pour the reaction solution into pre-cooled hydrochloric acid, filter, and the crude product is reconstituted with acid and alkali
P-diethylaminobenzaldehyde is obtained by recrystallizing crystals and ethanol.
Purpose
Analytical reagents, organic intermediates.
After acid-base reconstitution
P-diethylaminobenzaldehyde is obtained by recrystallizing crystals and ethanol.
Purpose
