Methyl Caprylate (CAS 111-11-5), also known as Methyl Octanoate, is a well-established organic compound with a characteristic fruity aroma and a wide array of applications. For professionals in the chemical industry, understanding its core properties, synthesis routes, and market dynamics is essential for informed sourcing and application development. This article provides a detailed overview, including insights for those looking to buy from reliable Chinese manufacturers and suppliers.

Chemical Properties and Characteristics:

Methyl Caprylate is a clear, colorless liquid with a molecular formula of C9H18O2 and a molecular weight of 158.24 g/mol. It possesses a distinctive winey, fruity, and orange-like odor, which makes it highly valuable in the flavor and fragrance industries. Its physical properties include a boiling point of approximately 194-195 °C and a flash point of 73 °C. It is sparingly soluble in water but readily dissolves in common organic solvents like ethanol and ether. Its density is around 0.878 g/cm³.

Synthesis Methods:

The most common industrial synthesis of Methyl Caprylate involves the esterification of octanoic acid (caprylic acid) with methanol. This reaction is typically catalyzed by a strong acid, such as sulfuric acid, to accelerate the process and improve yield. The reaction proceeds as follows:

RCOOH + CH3OH → RCOOCH3 + H2O

Where RCOOH represents octanoic acid and RCOOCH3 represents Methyl Caprylate.

This process involves mixing the reactants in a specific molar ratio, adding a catalytic amount of sulfuric acid, and heating the mixture under controlled conditions (typically 100-150 °C). After the reaction is complete, the Methyl Caprylate is separated and purified, often through distillation, to achieve the desired purity.

Alternative synthesis routes may involve transesterification of triglycerides derived from sources like coconut fatty acids with methanol. The choice of synthesis method often depends on the availability of raw materials, desired purity, and production scale.

Applications Across Industries:

The versatile nature of Methyl Caprylate leads to its use in numerous sectors:

  • Flavor & Fragrance: As a key aroma compound for fruity notes.
  • Cosmetics: Emollient, solvent, and fragrance component in skincare and personal care items.
  • Pharmaceuticals: Excipient, solvent, and potential antimicrobial agent.
  • Industrial Cleaning: Effective degreaser and solvent.
  • Chemical Intermediate: Used in the synthesis of other functional chemicals.
  • Biodiesel: A potential component for renewable fuels.

Market Insights and Sourcing:

The global market for Methyl Caprylate is driven by demand from these diverse industries. For businesses seeking to purchase this compound, identifying reliable suppliers is crucial. China has become a significant hub for chemical manufacturing, offering competitive prices and large-scale production capabilities.
