Di-tert-butyl peroxide or DTBP is an organic compound consisting of a peroxide group flanked by two tert-butyl groups. It is amongst the most stable organic peroxides. The peroxide bond undergoes homolysis at temperatures >100 °C, and for this reason di-tert-butyl peroxide is commonly used as a radical initiator in organic synthesis and polymer chemistry.

This compound will decompose aerobically and also anaerobically, making it a very interesting fuel source.

Decomposition reaction:

(CH₃)₃COOC(CH₃)_{3 (g)} → C₂H₆ (g) + 2 (CH₃)₂CO _(g)

Two Canadian scientists, H. O. Pritchard and P. Q. E. Clothier, have demonstrated and suggested the use of DTBP in engines where oxygen is limited, since it will work whether or not oxygen is present.
