Uses
Other comments :
Comparing it to other notes of the same type as Methyl Anthranilate or Dimethyl Anthranilate, Oranger Crystals has a distinctive almond smell.
Stability :
Stable in perfumes and diverse functional bases, except acid cleaners and bleaches. Very stable in fabric care products.
Uses in perfumery :
Oranger Crystals® is used in orange and white flowers notes for a warmth supply. Used in soaps and detergents for its stability. Tends to flatten formulas if overdosed.
Year of discovery :
1892
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.
Synthesis precursor :
Oranger Crystals® is not a precursor to the synthesis of another compound of olfactory interest.
Natural availability :
Oranger Crystals® is not available in its natural state.
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.
