Storage method

Should be sealed and stored in a cool place.

Synthesis method

Obtained from naphthalene through mixed acid nitration, acid separation, dehydration and drying. Also available byα-Preparation of nitronaphthalene, α-Nitronaphthalene is dissolved in sulfuric acid, add nitric acid in 80-90Nitrification produces dinitronaphthalene.

Purpose

Used as a sensitizer for ammonium nitrate explosives (the actual product is a mixture of isomers), carbide additives, and intermediates for sulfur dyes and organic synthesis.
