| Reactivity Profile | Isocyanates and thioisocyanates, such as 1,5-NAPHTHALENE DIISOCYANATE, are 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 in these materials. Some isocyanates react with water to form amines and liberate carbon dioxide. Base-catalysed reactions of isocyanates with alcohols should be carried out in inert solvents. Such reactions in the absence of solvents often occur with explosive violence, [Wischmeyer(1969)]. |
| Chemical Dangers | Decomposes on heating. This produces toxic fumes of nitrogen oxides, carbon monoxide, isocyanates and hydrogen cyanide. Reacts with acids, alcohols, amines, bases, strong oxidants, strong reducing agents and water. |

Anwendungen & Verwendung
Beschreibung
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.
Verwenden
