DescriptionECHEMI Editorial ReferenceCOLOURLESS LIQUID.
N-butyl isocyanate appears as a clear, colorless liquid with a pungent odor. Very toxic by ingestion, and may also be toxic by skin absorption and inhalation. Vapors heavier than air. Less dense than water and insoluble in water. Produces toxic oxides of nitrogen during combustion.|Liquid|COLOURLESS LIQUID.

Air and Water Reactions:Highly flammable. Extremely slow decomposition by water. Less dense than water and insoluble in water.
Reactive Group:Isocyanates and Isothiocyanates
Reactivity Alerts:Highly Flammable
Reactivity Profile:Isocyanates and thioisocyanates 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].
Autoignition Temperature:425 °C
Physical Dangers:The vapour mixes well with air, explosive mixtures are easily formed.
