• 化学的特性

  Butyl lactate has a faintly sweet, pleasant odor with buttery, creamy, milky, sweet, mushroom undertones. Two optically active and one racemic form of butyl lactate are known.

• 天然物の起源

  Reported found in cognac, cider and white wine.

• 使用

  n-Butyl lactate is used as a food and feed additive.

• 製造方法

  The racemic d-form is prepared by reacting zinc ammonium l-lactate with n-butyl alcohol in the presence of concentrated H2SO4; the l-form is prepared by reacting zinc ammonium d-lactate with n-butyl alcohol in the presence of HCl; the racemic form is prepared by several methods, one being from calcium or sodium lactate and n-butyl alcohol in benzene in the presence of H2SO4, with subsequent azeotropic distillation of the mixture.

• 調製方法

  n-Butyl lactate may be prepared via esterification of lactic acid and n-butyl alcohol.

• 一般的な説明

  A clear colorless liquid with a mild odor. Flash point 168°F. Less dense than water and insoluble in water. Vapors heavier than air. Used as a solvent, and to make other chemicals.

• 空気と水の反応

  Insoluble in water.

• 反応プロフィール

  Butyl lactate is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. Avoid contact with strong oxidizing agents and strong bases. Will not polymerize [USCG, 1999].

• 危険性

  Toxic. Upper respiratory tract irritant.

• 健康ハザード

  VAPOR: Headache, coughing, possible sleepiness, nausea or vomiting, or dizziness may result. LIQUID: Irritating to skin and eyes.

• 安全性プロファイル

  Poison by intraperitoneal route. A skin irritant. Toxic concentration in air for humans is about 4 ppm. Flammable when exposed to heat or flame; can react with oxidizing materials. To fight fire, use alcohol foam, foam, CO2, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes. See also ESTERS, n-BUTYL ALCOHOL, and LACTIC ACID.

• 職業ばく露

  Butyl lactate is a liquid. Molecular weight 5 146.19; boiling point 5 170C @ 760 mmHg; freezing/melting point 5 243C; flash point 5 71C(oc). Autoignition temperature 5 340
  382C. Hazard identification (based on NFPA-704 M Rating System): Health 1; flammability 2; reactivity 0 ?. Slightly soluble in water.

• 輸送方法

  A UN1993 Flammable liquids, n.o.s., Hazard Class: 3; Labels: 3—Flammable liquid, Technical Name Required.

• 不和合性

  May form explosive mixture with air. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides

• 廃棄物の処理

  Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.
