white crystals. The aroma is strong and strong, and the extreme dilution has the animal breath of Narcissus-like fragrance or Musk, which is also like the aroma of lily of the valley, Hyacinth and yellow impatiens. Freezing point above 73.5 °c; Boiling point 310 °c; Flash point> 100 °c. Insoluble in water, propylene glycol and glycerol.
The product is prepared by condensation of sodium phenolate or methylphenol with phenylacetyl chloride. After completion of the reaction, the crude product is washed with water and recrystallized.
It is used for the preparation of various essences, especially suitable for the preparation of Oriental, gardenia, ylang ylang, tuberosity, lily of the valley, Hyacinth and so on. It is also suitable for the modification of artificial musk.
