Mixtures of peroxyacetic acid and acetic anhydride may form explosive acetyl peroxide (MCA Case History No. 1795, Case Histories of Accidents in the Chemical Industry, Manufacturing Chemists' Association, Washington).
Organic peroxides vary widely in their self-reactivity, and inter-reactivity. In general these should be considered immediately reactive with any strong reducing agent. However, many of these materials may be completely compatible (unreactive) with other materials at ambient conditions, especially materials less prone to oxidation. Many of these substances sold commercially are already in some inert organic solvent such as mineral oil or even glycols. Note that, in general, organic hydroperoxides are more reactive than peroxides without a terminal hydrogen on the peroxide. See "Peroxides and Peroxide Compounds, Organic Peroxides" in Kirk-Othmer Encyclopedia of Chemical Technology, Wiley & Sons, December 2000. (Online)
Consequently, inadvertent mixtures with organic peroxides need to be vetted carefully on an individual basis. Caution should be used before proceeding. Further research of comparable examples in the literature or very small scale, carefully controlled experiments may be needed to fully assess compatibility.
