Industrial Applications of 1,2-BUTANEDIOL
| Industry | Applications | Process |
|---|---|---|
| Personal Care & Cosmetics | Humectant, solvent, preservative synergist | Added to emulsions, creams, shampoos, etc., typically at 0.5–5 wt% |
| Pharmaceuticals | Drug solvent, transdermal absorption enhancer, synthetic intermediate | Used in liquid formulation preparation and as a precursor in the synthesis of antifungal agents (e.g., terbinafine) |
| Coatings & Inks | Reactive diluent, film-forming aid, leveling agent | Copolymerized with acrylic monomers to improve film formation and gloss in low-VOC waterborne coatings |
| Fine Fragrances & Flavors | Fragrance stabilizer, fixative | Inhibits oxidative degradation in aldehyde- and ester-based fragrance systems, extending scent longevity |
| Pesticides | Adjuvant (wetting and dispersing agent, penetrant) | Formulated into suspension concentrates (SC) and emulsion-in-water (EW) formulations to enhance spreading and uptake of active ingredients on plant foliage |
Manufacturing Quality Control of 1,2-BUTANEDIOL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 1,2-butanediol by separation on a polar capillary column and flame ionization detection relative to an internal standard. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration using iodine generated in situ, based on the stoichiometric reaction with water. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Determines total acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Evaluates yellowness by comparing sample absorbance at 430 nm to platinum-cobalt standards or APHA color scale. |
| Density at 20 C | Digital Density Meter | Measures mass per unit volume using oscillating U-tube principle calibrated with water and air. |
| Refractive Index at 20 C | Refractometry | Determines ratio of light velocity in air vs. sample using critical angle measurement on a prism interface. |
| Residue on Evaporation | Gravimetric Analysis | Quantifies non-volatile residue after controlled evaporation of a known sample mass under specified temperature and vacuum. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Detects trace heavy metals by measuring absorption of characteristic atomic spectral lines after air-acetylene flame atomization. |
| Iron (Fe) Content | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Quantifies iron by measuring intensity of element-specific emission lines after high-temperature plasma atomization and excitation. |
| Aldehyde Content | Spectrophotometry after Reaction with DNPH | Measures aldehydes via hydrazone formation with 2,4-dinitrophenylhydrazine, followed by absorbance measurement at ~450 nm. |
| Chloride Ion | Ion Chromatography (IC) | Separates and quantifies chloride anions using anion-exchange column and suppressed conductivity detection. |
| Non-Volatile Residue on Ignition | Gravimetric Analysis after High-Temperature Ashing | Determines inorganic ash content by ignition of residue from evaporation at 600 C and weighing of remaining solids. |
