Properties and stability
Decomposes on contact with moisture. Avoid contact with strong oxidants, strong alkali, water, and humid air.
Storage method
Store in a cool, dry, well-ventilated warehouse. Keep away from fire and heat sources. Protect from direct sunlight. The packaging must be sealed and protected from moisture. They should be stored separately from oxidants, alkalis, etc. and avoid mixed storage. Equipped with the appropriate variety and quantity of fire equipment. Suitable materials should be available in the storage area to contain spills.
Synthesis method
Mix 60g of 4,4′-dinitrodiphenyldisulfide, 300ml of concentrated hydrochloric acid and 60ml of concentrated nitric acid, heat to 80°C, and introduce chlorine gas for reaction. At the end of the reaction, the generated sulfonyl chloride was poured out, washed with 80°C water to obtain a crude product, and recrystallized with glacial acetic acid to obtain 72g of p-nitrobenzenesulfonyl chloride.
Purpose
Used as analytical reagents and also used in organic synthesis.
