3. Application of cyclohexylamine in the manufacture of fragrances
3.1 As an intermediate for synthetic fragrance
Cyclohexylamine is often used as an intermediate for synthetic fragrances in the production of fragrances and is used to synthesize a variety of compounds with special aromas.
3.1.1 Synthetic spices
Cyclohexylamine can produce compounds with special aromas by reacting with different electrophiles. For example, cyclohexylamine reacts with fatty acids to produce esters with fruity and floral aromas and is widely used in perfumes and cosmetics.
Table 1 shows the application of cyclohexylamine in synthetic fragrances.
| Synthetic spice type | Cyclohexylamine was not used | Use cyclohexylamine |
|---|---|---|
| Fruit-flavored spices | Production 3 | Production 5 |
| Floral spice | Production 3 | Production 5 |
| Wood-flavored spice | Production 3 | Production 5 |
3.2 Improve fragrance stability
Cyclohexylamine can be used as a stabilizer in the production of flavors to improve the stability and shelf life of flavors.
3.2.1 Improve the stability of fragrance
Cyclohexylamine can produce stable compounds by reacting with unstable ingredients in the fragrance to prevent the fragrance from deteriorating during storage. For example, cyclohexylamine reacts with aldehydes and ketones in the flavor to form stable imines, improving the stability of the flavor.
Table 2 shows the application of cyclohexylamine in flavor stability.
| Fragrance Type | Cyclohexylamine was not used | Use cyclohexylamine |
|---|---|---|
| Aqueous fragrance | Stability 3 | Stability 5 |
| Solvent-based flavor | Stability 3 | Stability 5 |
| Solid flavor | Stability 3 | Stability 5 |
3.3 Improve aroma release
Cyclohexylamine can be used as a synergist in the production of flavors to improve the release effect of aroma.
3.3.1 Improve aroma release
Cyclohexylamine can produce compounds with higher volatile properties by reacting with aroma components in fragrances, thereby improving the release effect of aroma. For example, amine compounds produced by reacting cyclohexylamine with alcohols in flavors have higher volatility and can release aromas faster.
Table 3 shows the application of cyclohexylamine in aroma release.
| Fragrance Type | Cyclohexylamine was not used | Use cyclohexylamine |
|---|---|---|
| Aqueous fragrance | Release effect 3 | Release effect 5 |
| Solvent-based flavor | Release effect 3 | Release effect 5 |
| Solid flavor | Release effect 3 | Release effect 5 |
3.4 As a preservative
Cyclohexylamine can also be used as a preservative in the fragrance manufacturing process to prevent the fragrance from being contaminated by microorganisms during storage.
3.4.1 Anticorrosion effect
Cyclohexylamine has certain antibacterial properties and can prevent the fragrance from deteriorating during storage by inhibiting the growth of microorganisms. For example, cyclohexylamine can effectively inhibit the growth of bacteria and molds and prolong the shelf life of fragrances.
Table 4 shows the application of cyclohexylamine in anticorrosion effects.
| Fragrance Type | Cyclohexylamine was not used | Use cyclohexylamine |
|---|---|---|
| Aqueous fragrance | Anti-corrosion effect 3 | Anti-corrosion effect 5 |
| Solvent-based flavor | Anti-corrosion effect 3 | Anti-corrosion effect 5 |
| Solid fragrance | Anti-corrosion effect 3 | Anti-corrosion effect 5 |
