The crystallization of peroxide/solvent mixtures with peroxide contents from 10 to 65 wt.‐% is studied between −50 and +30 °C up to 3 000 bar for di‐ tert‐ butylperoxide, tert‐ butyl peroxyacetate, tert‐ butyl peroxypivalate, tert‐ butyl peroxy‐2‐ethylhexanoate, and bis( tert‐ butyl) peroxybutanoate with decane, octane, isododecane, isooctane, and isopar H as solvents. The liquid/solid phase behavior indicates miscibility in the liquid and immiscibility in the solid phase. With tert‐ butyl peroxyacetate/isododecane, in addition, liquid/liquid immiscibility occurs. A few melting pressure curves are presented for ternary systems containing either two solvents or two peroxides.
