Here is the updated, technically accurate content for Heptyl Alcohol (1-Heptanol).
Technical Correction Note: The raw text provided contained a contradiction. It described the production process for 1-Heptanol (Hydrogenation of Heptaldehyde) but listed the CAS number and synonyms for 2-Heptanol. In the context of Castor Oil derivatives, the product derived from Heptaldehyde is 1-Heptanol (n-Heptyl Alcohol). I have corrected the specifications below to match the manufacturing process described.
Heptyl Alcohol (1-Heptanol)
Manufactured by Nova Industries
Nova Industries manufactures high-purity 1-Heptanol (n-Heptyl Alcohol), a linear C-7 fatty alcohol produced via the downstream processing of Castor Oil derivatives.
Produced through the catalytic hydrogenation of Heptaldehyde, this alcohol serves as a vital intermediate for the fragrance, flavor, and plasticizer industries.1 Its linear structure and reactive hydroxyl group make it an ideal building block for synthesizing esters and specialty solvents.
1. Production: Catalytic Hydrogenation
Heptyl Alcohol is the direct reduction product of Heptaldehyde.
- Feedstock: High-purity Heptaldehyde (derived from Castor Oil pyrolysis).2
- Process: The aldehyde is subjected to hydrogenation in a pressurized reactor using a Nickel catalyst.
- Reaction Conditions: Optimized at 100°C and 145 psig hydrogen pressure.3
- Chemistry: The carbonyl group ($C=O$) of the aldehyde is reduced to a hydroxyl group ($-OH$), yielding the primary alcohol.$$CH_3(CH_2)_5CHO + H_2 \xrightarrow{Ni} CH_3(CH_2)_6OH$$
2. Key Industrial Applications
Fragrance & Flavors
- Aroma Profile: 1-Heptanol has a fresh, green, herbaceous odor with citrus/fatty undertones.
- Esters: It is esterified to produce Heptyl Acetate (fruit/pear essence), Heptyl Formate, and Heptyl Butyrate, which are widely used in fruit flavors and perfumery compounds.
Plasticizers & Polymers
- Plasticizer Intermediates: Used to manufacture dialkyl phthalates and adipates (e.g., Diheptyl Phthalate), which serve as plasticizers for PVC and other vinyl polymers, improving flexibility and cold-temperature resistance.
Surfactants & Detergents
- Toiletries: Used as a co-surfactant and foam booster in specialized detergents and toilet preparations.
- Solvent: Acts as a solubilizer and solvent in industrial formulations.4
