Propyl isocyanate is an organic chemical compound of carbon, hydrogen, nitrogen, and oxygen with the linear formula CH3CH2CH2NCO.[2][3]
Propyl isocyanate is usually produced by a condensation reaction or by Fischer–Speier esterification with sulfuric acid as a catalyst.
Physical properties
Propyl isocyanate is sparingly soluble in water, reacts with water, but very soluble in alcohol, diethyl ether, chloroform, and most organic solvents.[4]
The compound forms a highly flammable, colorless liquid with a sharp odor. Very toxic by ingestion, may cause burns and death.[5][6]
