Synthesis route :
Oranger Crystals® is synthesized from naphthalene by a Friedel-Craft acetylation, and by reacting it with chloroacetic acid for example, in the presence of aluminum chloride. The more polar the solvent used in the synthesis, the larger the quantity of beta isomer in Orange Crystals®. The alpha product is not desired.
Synthesis precursor :
Oranger Crystals® is not a precursor to the synthesis of another compound of olfactory interest.
Isomerism :
alpha-Methyl Naphthyl Ketone, also known as Oranger Liquid®, is a liquid that also has a smell similar to orange blossom. This compound is nevertheless dissociated from Oranger Crystals® in perfumery.
Diphenyl Oxide is an isomer of Oranger Crystals®, but it has a very different smell as it is rosy and fruity.
