Properties and stability
Avoid contact with oxides and acetic acid.
Storage method
Use water as a stabilizer during storage. Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Protect from direct sunlight. Keep container sealed and strictly prohibited from contact with air. Should be used with oxidants, acetic acid, food
Chemicals should be stored separately and avoid mixed storage. Use explosion-proof lighting and ventilation facilities. It is prohibited to use mechanical equipment and tools that are prone to sparks. Suitable materials should be available in the storage area to contain spills.
Synthesis method
Replace N,N-diethylaniline, The mixture of concentrated hydrochloric acid and ethanol is cooled to 0℃The following, mix with isoamyl nitrite and stir for reaction2-3h. The reaction solution was extracted with diethyl ether to remove isoamyl alcohol. For remaining liquid
Neutralize excess sodium carbonate solution until it becomes alkaline, and extract with ether. The ether extract is salted with concentrated sulfuric acid in absolute ethanol and filtered to obtain p-nitroso-N,N-diethylaniline sulfate, which is treated with carbonic acid
Sodium neutralizes and precipitates free p-nitroso group-N, N-Diethylaniline.
Purpose
For organic synthesis.
