Other names :
Phenoxybenzene ; 1,1-oxybis benzene ; Biphenyl oxide ; Diphenyl ether ; Geranium crystals ; Phenyl ether ; Phenyl oxide
Uses in perfumery :
Diphenyl Oxide is used in all types of perfumes, for reconstitutions of rose, geranium and lavender. Gets on well with citruses to boost the head and make the note last longer. Gives a metallic and cold effect. Widely used in functional perfumery.
Natural availability :
Diphenyl Oxide is not available in its natural state.
Year of discovery :
Data not available.
Other comments :
In comparision to Benzophenone, Diphenyl Oxide has a smell more reminiscent of plastic.
Price Range :
Stable in perfumes and diverse functional bases

Synthesis route :
Diphenyl Oxide is synthesized as an intermediate in the synthesis of phenol. This synthesis is done by hydrolysis of chlorobenzene under a very high pressure.
Synthesis precursor :
Diphenyl Oxide is not a precursor to the synthesis of another compound of olfactory interest.
Oranger Crystals® is a constitutional isomer of Diphenyl Oxide although it does not have the same smell, as it is closer to orange blossom.
