Linalyl acetate orange

Petitgrain oil Paraguay is obtained from an acclimatized variety of the bitter orange tree. Citrus aurantium L. subsp. aurantium, which is grown in Paraguay. It is pale yellow liquid with a characteristic, strong, pleasant odor, reminiscent of linalool and linalyl acetate. 

Definition Aq. sol n. of the odoriferous principles of the flowers of the orange. Citrus aurantium var. dulcis] constituents are limonene, l-linalool, geraniol, linalyl acetate (7-18%), some methyl anthranilate, nerol, neroli camphor Properties YIsh. fluorescent liq. turns brown on exposure to light very intense, pleasant odor sol. in DMSO, 95% ethanol, acetone sol. < 1 mg/ml in water sp.gr. 0.86-0.88 flash pt. > 93.3 C ref. index 1.475 (20 C) pH neutral or si. acid to litmus volatile... 

The volatile oil (bitter orange oil) contains more than 90% monoterpenes (main f-limonene, also myrcene, campherr pinene, ocimene, p-cymene, etc.) small amounts of alcohols (linalool, terpinene nerol, farnesol, nerolidol, octanol, etc. usually 0.5-1% aldehydes (mainly decanal also nonanal, dodecanal, citronellal, neral acetaldehyde, formaldehyde, etc.), and ketones (carvone, a-ionone, and jasmine) free acids (octadeca-dienoic, pelargonic, cinnamic, acetic, etc.) about 2.4% esters (linalyl acetate, decyl pe-largonate, octyl acetate, geranyl acetate, etc.) coumarins (osthole and auraptenol) and others (jiangsu list and horhammer). 

Although limonene is also the main component, at 92.95 to 95 %, the content of other constituents differs from that of sweet orange oil i.e., its aldehyde content is lower and its ester (e.g. linalyl and geranyl acetate) content is higher [369, 379a, 379b, 394, 423-428].
