Chemical Description

  • 1-Butanol is the most important in industries and the most extensively studied. 1-Butanol is a colorless liquid with a strong, mildly alcoholic odor. It is used in chemical derivatives and as a solvent for paints, waxes, brake fluid, and cleaners.
  • Butanol is the allowable food flavors documented in the "food additives health standards'’ of China. It is mainly used for the preparation of food flavors of bananas, butter, cheese and whiskey. For the candy, the usage amount should be 34 mg/kg; for baked foods, it should be 32 mg/kg; for soft drinks, it should be 12 mg/kg; for cold drinks, it should be 7.0mg/kg; for the cream, it should be 4.0mg/kg; for alcohol, it should be 1.0mg/kg.
  • It is mainly used for the manufacture of the n-butyl plasticizers of phthalic acid, aliphatic dicarboxylic acid and phosphoric acid that are widely applied to various kinds of plastic and rubber products.
  • It can also be used as the raw material of producing butyraldehyde, butyric acid, butyl-amine and butyl lactate in the field of organic synthesis.
  • It can also be used as the extraction agent of oil, drugs (such as antibiotics, hormones and vitamins) and spices as well as the alkyd paint additives. It can be used as the solvent of organic dyes and printing ink and dewaxing agents.
  • 1-Butanol is a colorless, volatile liquid with a rancid sweet odor. The air odor threshold of 1-butanol was reported to be 0.83 ppm ; others have identified the minimum concentration with identifiable odor as 11 and 15 ppm.
  • Clear, colorless liquid with a rancid sweet odor similar to fossil oil. Experimentally determined detection and recognition odor threshold concentrations were 900 μg/m3 (300 PPBv) and 3.0 mg/m3 (1.0 PPMv), respectively.Odor threshold concentration in water is 500 ppb.
  • The least detectable odor threshold in concentration water at 60 °C was 0.2 mg/L (Alexander et al., 1982). Cometto-Mu?iz et al. (2000) reported nasal pungency threshold concentrations ranging from approximately 900 to 4,000 ppm.
