For chemists, formulators, and procurement specialists in the chemical industry, understanding the fundamental properties and manufacturing processes of key compounds is essential. 1-Nonanal (CAS 124-19-6), commonly known as Aldehyde C-9 or Pelargonaldehyde, is a fascinating organic molecule with significant industrial applications, particularly in the fragrance and flavor sectors. As a leading chemical manufacturer, we are pleased to share insights into its chemistry.

Molecular Structure and Identity

1-Nonanal is a linear saturated aliphatic aldehyde with the chemical formula C9H18O. Its structure consists of a nine-carbon chain with an aldehyde group (-CHO) at the terminal position. This simple yet effective functional group dictates much of its reactivity and sensory properties. Its molecular weight is approximately 142.24 g/mol.

Key Physical and Chemical Properties

The physical characteristics of 1-Nonanal are crucial for its handling and application:

  • Appearance: Typically, it presents as a colorless to pale yellow liquid.
  • Odor: Possesses a characteristic waxy, citrus, and subtly green aroma.
  • Boiling Point: Around 191 °C (at atmospheric pressure), but often cited under vacuum, e.g., 93 °C at 23 mmHg.
  • Density: Approximately 0.827 g/mL at 25 °C.
  • Solubility: Slightly soluble in water but soluble in organic solvents like ethanol and ethyl acetate.
  • Flash Point: A relatively low flash point, indicating flammability, necessitating careful handling.

These properties make it easy to incorporate into various formulations, whether liquid bases for perfumes or complex flavor mixtures. For formulators looking to buy 1-Nonanal, understanding these properties ensures proper integration.

Industrial Synthesis of 1-Nonanal

The commercial production of 1-Nonanal is primarily achieved through the hydroformylation of 1-octene. This process, also known as the Oxo process, involves the reaction of an alkene with syngas (a mixture of carbon monoxide and hydrogen) in the presence of a catalyst (typically rhodium or cobalt based). The reaction adds a formyl group (-CHO) and a hydrogen atom across the double bond of 1-octene, yielding predominantly 1-Nonanal.

The efficiency and selectivity of the catalyst and reaction conditions are critical for obtaining high yields of the desired linear aldehyde. Advances in catalysis have made this a cost-effective method for large-scale production, allowing manufacturers like us to supply 1-Nonanal reliably to the global market.
