Decomposition Rate of Allyl Isothiocyanate in Aqueous Solution

The decomposition rate of allyl isothiocyanate (AITC) in a low concentration range (below 1.6 mM) follows the first-order rate equation, and its degradation kinetics can be explained by the nucleophilic attack of water molecules and hydroxide ions on the AITC molecule. In aqueous solution, pH and temperature were important in the decomposition of AITC; especially the temperature had a large influence on its rate.
