As a precursor to the development of effective vat management and waste disposal strategies, the kinetics and basic mechanisms of amitraz, N'-(2,4-dimethylphenyl)-N-[[(2,4- dimethylphenyl)imino]-methyl]-N-methylmethanimidamide, hydrolysis were examined as was the effect of cosolvents and metal ions. Amitraz was readily hydrolyzed at low pH values, forming acid-stable 2,4-dimethylphenylformamide, which can be further hydrolyzed to 2,4-dimethylaniline. The hydrolysis of 2,4-dimethylphenylformamide was faster under basic conditions. Thus, the addition of lime, a management technique used to stabilize the amitraz, will enhance the hydrolysis of its degradation products to aniline.
