Canonical SMILES:C1=CC2=C(C=CC=C2N=C=O)C(=C1)N=C=O
Inhalation Risk:Evaporation at 20 °C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed, especially if powdered.
Effects of Short Term Exposure:The substance is irritating to the eyes, skin and respiratory tract.
Effects of Long Term Exposure:Repeated or prolonged inhalation may cause asthma.
Description Naphthalene diisocyanate (NDI) occurs as white to lightyellow crystalline flakes with a characteristic odor. NDI is incompatible with many classes of compounds, reacting exothermically to release toxic gases. Reactions with amines, aldehydes, alcohols, alkali metals, ketones, mercaptans, strong oxidizers, hydrides, phenols, and peroxides can cause vigorous releases of heat. Acids and bases initiate polymerization reactions. NDI can react with water to form amines and liberate carbon dioxide.
Uses Manufacture of polyurethane solid elastomers. Naphthylene 1,5-diisocyanate is mainly used for the production of elastomers. NDI is used as a curing agent in the manufacture of elastomers.
