Aroma chemicals are one of the characters important constituents and properties of aroma. Aromas are attention-grabbing, nominative, distinctive flavors and fragrances. It is used in flavor compositions such as vanillin, citronilla and its esters, zeraniol / nerol and its esters, linalool and its esters, L-menthol and terpineol and its esters.

Aroma chemicals are used to make fragrances. A growing word population and increasing food farming will require large amounts of labor and space. For large production, the need for natural sources, such as flowers, and labor costs can be very important. Very important oils like sandalwood or its trees are in very small quantities. And along with it comes political reasons.

Currently synthetic varieties are available from reasonable sources through petrochemicals. In which the following four products are classified for Aromatic Chemicals, Flavors and Fragrances in Aero. including venzinoides, turpentine oil or turpentine musk chemicals and misc.

Other products include natural aroma chemicals derived from essential oils, oleoresins and other natural extracts. Another type of synthetic aroma chemicals is obtained by a different technology. It includes classical reactions such as nitration, Friedel-Kaft reaction, Grignard reaction as well as distillation and purification are very important.

Ninety percent of aroma chemicals are esters, ketones, alcohols, aldehydes with molecular weights less than 300, which contain five percent unsaturated hydrocarbons. There are about 3000 types of chemicals used to make other flavors and fragrances. Its content is estimated at about 50 metric tons annually. About their extra chemicals.

Benzyl Acetate: Benzyl acetate is obtained by esterification of benzyl alcohol or benzyl chloride and sodium acetate. Its test is of pair type. These products are useful for making jasmine perfumes.

Benzyl salicylate: Benzyl salicylate is obtained by condensation of benzyl chloride and sodium salicylate. It is used as a fruit-flavor.

Methyl Salicylate : Methyl salicylate is obtained by esterification of salicylic acid. It is used in root-beer mouthwash chewing gum.

Raspberry Ketone : 1-(4-Hydroxyphenyl)-3-butanone : which is obtained by condensation of p-hydroxy benzaldehyde with ketone. Alternatively, phenol and methyl vinyl ketone are obtained by hydrogenation or Friedel Fraft.

* A-amyl minamaldehyde : which is obtained by alkaline condensation of heptane. Benzaldehyde is used as imitation apple, apricot, peach, strawberry flavors. Also used as a jasmine note as a fragrance. Which can be used in soap, detergent.
