A shock-sensitive explosive. Upon decomposition it emits acrid smoke and fumes.

 Di-tert-butyl diperoxyphthalate (CAS NO.2155-71-7) is also called 1,2-Benzenedicarboperoxoic acid, bis(1,1-dimethylethyl) ester ; Di-(terc-butilperoxi)ftalato [Spanish] ; Di-tert-butyl diperphthalate ; Di-tert-butyl perphthalate ;
Diperoxyphtalate de tert-butyle [French] ; Kayaester PH ; Lupersol KDB ; NSC 43583 ; Perbutyl MA ; Trigonox 111 . Di-tert-butyl diperoxyphthalate (CAS NO.2155-71-7) is crystalline solid mixed with water. Water can lessen the explosion hazard. Peroxides, such as Di-tert-butyl diperoxyphthalate (CAS NO.2155-71-7) , are good oxidizing agents. Organic compounds can ignite on contact with concentrated peroxides. Strongly reduced material such as sulfides, nitrides, and hydrides may react explosively with peroxides. There are few chemical classes that do not at least produce heat when mixed with peroxides. Many produce explosions or generate gases (toxic and nontoxic). Generally, dilute solutions of peroxides (<70%) are safe, but the presence of a catalyst (often a transition metal such as cobalt, iron, manganese, nickel, or vanadium) as an impurity may even then cause rapid decomposition, a buildup of heat, and even an explosion. Solutions of peroxides often become explosive when evaporated to dryness or near-dryness.
