2,4-Toluene Diisocyanate

CAS RN:584-84-9

Reactivities / Incompatibilities

Strong oxidizers, water, acids, bases, and amines (may cause foam and spatter); alcohols [Note: Reacts slowly with water to form carbon dioxide and polyureas].
Liquid is heavier than water and reacts with water, forming carbon dioxide.
0.9-9.5 vol % in air. Reacts violently with amines, alcohols, bases and warm water, causing explosion hazards.
Reacts readily with cmpd containing active hydrogens, such as water, acids and alc; contact with bases, such as caustic soda and tertiary amines, may cause uncontrollable polymerization and rapid evolution of heat; high temp can cause formation of dimer.
Polythene containers holding the diisocyanate may harden and burst in prolonged storage, because of slow absorption of water vapor through the wall leading to urea deposition from hydrolysis and generation of pressure of liberated carbon dioxide.
It can react with aniline. The heat of this reaction may be sufficient to ignite surrounding combustibles and the material itself. /Toluene diisocyanate/
