4-ISOPROPYLBENZYL ALCOHOL Usage And Synthesis

Description

p-Isopropylbenzyl alcohol has an intense, persistent, caraway-like odor and an aromatic, burning taste. Prepared from cuminaldehyde with H2 or NH3 under pressure in methanol solution and in the presence of Raney Ni catalyst; or by catalytic reduction of methyl p-isopropy lbenzoate.

Chemical Properties

4-Isopropylbenzyl alcohol is a clear colourless to slightly yellow liquid. Very poorly soluble in water, soluble in alcohol and oils. Sp.Gr. 0.98. B.P. 248℃. Oily-spicy odor, suggestive of Dillseed or Caraway, but not pungent or sharp like Carvone. Warm, almost burning, spicy-oily-woody taste.

Chemical Properties

p-Isopropylbenzene alcohol has an intense, persistent, caraway-like odor and an aromatic, burning taste

Occurrence

Reported found in the oil from fruits of Cuminum cyminum and Carum carvi L.; also in the oils of Eucalyptus bakeris (esterified) and French lavender. Also reported found in mandarin peel oil, lingonberry, black currants, blackberry, tomato, cumin seed, peppermint oil, nutmeg, thymus, cognac, licorice, lovage seed, dill, laurel, turmeric, calabash nutmeg, angelica root oil and mastic gum leaf and fruit oil

Uses

4-Isopropylbenzyl alcohol is occasionally used in perfume compositions for its natural and warm-herbaceous-spicy effect, perceptible in the topnote and often through the dryout. Also used in the artistic duplication of certain floral notes, such as Mimosa and Cassie, particularly in connection with Methylionones. Finds some use in flavor compositions, mainly Berry, Fruit, Spice and Liquor flavors. The concentration in the finished product will normally be about 0.5 to 35 ppm.

Definition

Found in caraway seed.

Preparation

From cuminaldehyde with H2 or NH3 under pressure in methanol solution and in the presence of Raney Ni catalyst, or by catalytic reduction of methyl p-isopropylbenzoate

General Description

4-Isopropylbenzyl alcohol has mosquito repellent properties and has been isolated from Eucalyptus camaldulensis. Oxidation of 4-isopropylbenzyl alcohol over TiO₂-supported nano gold catalyst has been investigated.
