Amyl acetate, CH3·COOC5H11, and linalyl acetate, CH3·COOC10H17, the latter occurring in the oils of lavender and bergamot, are typical esters classed as essential oils.

Among the constituents of this oil are: linalyl acetate, limonene, dipentene, linalol, and bergaptene.

Among its constituents are limonene, linalyl acetate, geraniol and geranyl acetate.

Thus, to find the percentage as linalyl acetate, the number of c.c. absorbed would be multiplied by 0.196 and by 100, and divided by the weight of oil taken.

Specific gravity at 15° C., 0.875-0.882; optical rotation, +0° 40' to +10°, and occasionally much higher; refractive index at 20° C., 1.468-1.470; esters, calculated as linalyl acetate, 10-18 per cent.; soluble in 0.75-1.75 volumes of 80 per cent. alcohol, becoming turbid on further addition of alcohol.
