n-Hexanol, also known as 1-hexanol or n-hexanal alcohol, is a six-carbon straight-chain saturated fatty primary alcohol. It is also naturally found in trace amounts in citrus fruits and berries. Its chemical formula is usually written as:
C6H14O (CH3(CH2)5OH, CAS No.: 111-27-3, molecular weight approximately 102.17)
It is a colorless and transparent liquid at room temperature, with a faint bluish aroma of tender leaves, and a slight hint of wine, fruit, and fat. Its density is approximately 0.814~0.819 g/cm³, melting point is approximately -46.7~-52℃, boiling point is approximately 156~158℃, flash point is approximately 59℃, and refractive index is approximately 1.417~1.419. Hexanol is slightly soluble in water (approximately 6 g/L at 25℃) and miscible with ethanol, propylene glycol, and oils. Its vapor density is 4.5.
From a molecular structure perspective, n-hexanol consists of a six-carbon straight chain and a terminal hydroxyl group (-OH), belonging to a typical aliphatic primary alcohol. The hydroxyl group endows it with polarity, reactivity, and a certain degree of water solubility, while the six-carbon long chain endows it with oil solubility and compatibility with resins and oils—this "polar hydroxyl group + hydrophobic long chain" structure allows it to act as a solvent to dissolve resin inks, and also as a raw material for esterification into plasticizers and fragrance components, forming the basis for its widespread application in coatings, inks, fragrances, and plasticizers.
Chemically, n-hexanol exhibits typical properties of primary alcohols: it can be oxidized to hexanoic acid, esterified to form hexanoate esters, and reacted with isocyanates to form polyurethanes; it is flammable, its vapor can form explosive mixtures with air, and it is slightly irritating to the eyes. It should be stored in a sealed container, away from fire and heat sources.
Industrial-grade n-hexanol refers to products primarily intended for industrial production, with a purity generally above 99%. Compared to reagent-grade and other specifications, industrial-grade products place greater emphasis on the following indicators:
purity
Purity directly affects solvent performance and downstream synthesis yield; industrial grade generally requires a main content of over 99%.
Moisture
Excessive moisture content can affect the drying performance of the solvent and the esterification reaction, so it needs to be controlled at a low level.
acid value
Acid value reflects the content of free acid, which affects product stability and downstream applications, and needs to be controlled at a low level.
chromaticity
It should be colorless and transparent; abnormal color often indicates impurities or oxidation.
Density and refractive index
Density (0.814~0.819) and refractive index are common indicators for judging purity and quality, and they must meet specifications.
Hexanol is an important solvent, used as a solvent for dyes, rubber, specialty printing inks, oils and natural resins, and also as a co-solvent for nitrocellulose. With its excellent solubility for a variety of resins and oils, it serves the coatings, inks and rubber industries.
Hexanol is an important raw material for the synthesis of hexyl ester plasticizers, used to produce plasticizers such as hexyl adipate, which helps improve the flexibility and processing performance of plastics such as PVC.
Hexanol and its carboxylic acid esters (such as hexanoate) are found in trace amounts in citrus and berry fruits, and have a fresh fruity aroma. They are used as flavoring ingredients in food flavorings and daily fragrances, serving the food and cosmetics industries.
Hexanol is a primary alcohol surfactant raw material that can be used in industrial processes to enhance interfacial properties and help improve emulsification, wetting and dispersion effects. It is used in daily chemical and industrial surfactant systems.
Hexanol is used in the production of synthetic lubricating oils. Its ester derivatives have good lubricating properties and can also be used as additive components in lubricating oils.
Its applications, including inkjet ink additives, fiber softeners, and extractants, continue to expand.
n-Hexanol, or 1-hexanol, is a colorless, transparent, six-carbon straight-chain primary alcohol with a fresh fruity and leafy aroma. It is naturally found in trace amounts in citrus and berry fruits, possessing both excellent solvent properties and rich chemical reactivity. In daily life, we indirectly encounter it through the supply chain of fragrances, printing inks, plastic products, paints, and daily chemical cleaning products. In industry, industrial-grade n-hexanol is widely used as a solvent (core) in dyes, rubber, and printing inks; a raw material for hexyl ester plasticizers; a component of food and daily-use fragrances; a raw material for surfactants; and a component of synthetic lubricants. It is an important aliphatic primary alcohol connecting "daily-use" products with "paints, fragrances, and plastics."
