Hexylene Glycol Usage And Synthesis
  • Chemical PropertiesHexylene Glycol is an oily colorless liquid with a mild sweet odor. It is an oxygenated solvent derived from acetone which has two alcohol functions. It has a low evaporation rate and it is completely miscible with water.
  • Uses
    1. Hexylene Glycol is used as a reagent in the synthesis of functionalized boronic esters. it is used in laboratory studies as a precipitant and cryoprotectant in protein crystallography.
    2. Also used in the preparation of vinylboronates.
    3. It is mainly used  as a coupling agent and an additive to hydraulic fluids, inks and cement. Further, it is used as a solvent for cleaning and colorant products.
    4. It is a potential substitute for glycol ethers.
    5. It is an effective shrinkage reduction admixture or SRA for concrete and mortar.
    6. It can also be used as a building block in chemical synthesis.
    7. Hexylene glycol is a key solvent in many markets such as paints & coatings, metal working fluids, detergency, cosmetics & fragrances, textiles & leather.It is used to control the flow properties of industrial products such as paints, coatings, cleansers, solvents, and hydraulic fluids. It acts as a thickening agent in cosmetic products.
    8. It is also employed as a blood volume expander.
  • Useshexylene glycol could be considered a solubilizer.
  • UsesFuel and lubricant additive; solvent in cosmetics; solvent in petroleum refining; coupling agent in hydraulic brake fluid and printing inks; gasoline anti-icer additive
  • Production Methods2-Methyl-2,4-pentanediol is prepared commercially by the catalytic hydrogenation of diacetone alcohol . It is used as a chemical intermediate, a selective solvent in petroleum refining, a component of hydraulic fluids, a solvent for inks, and as an additive for cement . Industrial exposure is likely to be from direct contact or from inhalation, particularly if the material is heated.
  • DefinitionChEBI: A glycol in which the two hydroxy groups are at positions 2 and 4 of 2-methylpentane (isopentane).
  • General DescriptionOily colorless liquid with a mild sweet odor. Floats and mixes slowly with water.
  • Air & Water ReactionsHygroscopic. Water soluble [Hawley]
  • Reactivity Profile2-Methyl-2,4-pentanediol is incompatible with the following: Strong oxidizers, strong acids [Note: Hygroscopic (i.e., absorbs moisture from the air).] .
  • HazardToxic by ingestion and inhalation; irritant to skin, eyes, and mucous membranes. Combustible.
  • Health HazardIrritation of eyes, nose and throat; headache, dizziness, and nausea.
  • Chemical ReactivityReactivity with Water No reaction; Reactivity with Common Materials: Can catch fire when in contact with porous materials such as wood, asbestos, cloth, soil, or rusty metals; Stability During Transport: Stable at ordinary temperatures, however when heated this material can decompose to nitrogen and ammonia gases. The decomposition is not generally hazardous unless it occurs in confined spaces; Neutralizing Agents for Acids and Caustics: Flush with water and neutralize the resulting solution with calcium hypochlorite; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.
  • Purification MethodsDry the diol with Na2SO4, then CaH2 and fractionally distil it under reduced pressure through a packed column, taking precautions to avoid absorption of water. [Beilstein 1 IV 2565.]
