MBT is light yellow acicular crystal, slightly soluble in water,
soluble in hot ethanol, DMF, NMP, diethylene glycol monoether, etc.
A mixture of cyclohexanone and xylene. The decomposition
temperature is 130 C, which is stable under acidic conditions. When
the pH value is greater than 8.5, the decomposition temperature is
Start hydrolysis. Its hydrolysates thiocyanate, formaldehyde and a
small amount of sulfide have low toxicity, so they will not cause
