Cinnamonitrile Usage And Synthesis

Cinnamonitrile Usage And Synthesis

Properties: 

    Cinnamon nitrile is a colorless to slightly yellow liquid. Its aroma is very similar to natural cinnamon, with a strong spicy floral aroma.

Uses: 

    Cinnamon nitrile is an excellent artificial synthetic fragrance, the aroma is very similar to natural cinnamon, with a strong spicy floral fragrance, especially in alkaline medium, it shows its advantages of high strength, stable performance, good durability, and no irritation or allergic effect on the skin. It is widely used in spices. Chemicalbook is cinnamaldehyde, but cinnamaldehyde is unstable in the air and easily oxidized and discolored, and even more unstable under the action of heat and alkali. The aroma of cinnamon nitrile is similar to cinnamaldehyde, but it is very stable, stable to light, heat, acid, and alkali, does not oxidize, does not discolor, and can maintain the original aroma and color. It is an excellent substitute for cinnamaldehyde.

Flavors and spices: 

    Cinnamonitrile, also known as styryl cyanide, is an excellent synthetic fragrance with a strong cinnamon-like spicy aroma and floral fragrance. It is a colorless or light yellow viscous liquid with stable chemical properties. It does not change when exposed to light, heat, acid, or alkali. It has no toxic side effects on the human body, no irritation or allergic reaction when in contact with the skin. Compared with cinnamaldehyde, cinnamonitrile has stronger permeability, strong and lasting fragrance, and less irritation and toxicity to the skin than cinnamaldehyde. It is an ideal substitute for cinnamon oil and cinnamaldehyde. It can be used in the formulation of daily chemical flavors, mainly in the formulation of soap flavors and detergent flavors, with an amount of less than 2%. IFRA has no restrictions. Because cinnamonitrile has a unique chemical structure and can undergo Friedel-Crafts, addition, reduction, hydrolysis and other reactions, it is also widely used in the fields of medicine and fine chemicals. According to the information provided by RIFM, the acute toxicity data of cinnamonitrile: oral LD50 4.15g/kg (rat), skin test LD50> 5g/kg (rabbit). Cinnamonitrile can be obtained by condensation of benzaldehyde and acetonitrile in the presence of potassium hydroxide solution; or by converting cinnamaldehyde into aldoxime and then dehydrating it.

Chemical properties: 

    Light yellow transparent liquid with a strong and warm spicy floral aroma

Uses: 

    Cinnamon nitrile is an extremely stable nitrile-based spice with an aroma very similar to natural cinnamon.

    Used in the synthesis of medicines, fragrances and electronic chemicals, etc.

Production method: 

    Cinnamaldehyde and hydroxylamine hydrochloride react in the presence of pyridine to generate aldoxime through addition-elimination reaction, which is then azeotropically dehydrated with toluene to obtain cinnamonitrile.
