• 説明

  Decanoic acid, or capric acid, is a saturated fatty acid. Its formula is CH₃(CH₂)₈COOH. Salts and esters of decanoic acid are called decanoates or "caprates". The term capric acid arises from the Latin "capric" which pertains to goats due to their olfactory similarities.
  Capric acid occurs naturally in coconut oil (about 10%) and palm kernel oil (about 4 %), otherwise it is uncommon in typical seed oils. It is found in the milk of various mammals and to a lesser extent in other animal fats.
  Two other acids are named after goats: caproic (a C6 fatty acid) and caprylic (a C8 fatty acid). Along with decanoic acid, these total 15 % in goat milk fat.

• 天然物の起源

  Reported found in apple, beer, preferments of bread, butter, oil, cheese, blue cheese, Romano cheese, cheddar cheese, Roquefort cheese, roasted cocoa bean, cognac, muscat grape, grape musts and wine, and other natural sources. Also reported in citrus peel oils, orange juice, apricots, guava, papaya, strawberry, butter, yogurt, milk, mutton, hop oil, Bourbon and Scotch whiskey, rum, coffee, mango and tea.

• 使用

  Decanoic acid is used in manufacturing of esters for artificial fruit flavors and perfumes.

• 製造方法

  Decanoic acid is prepared from Coconut oil by saponification.

• 定義

  ChEBI: Decanoic acid is a C10, straight-chain saturated fatty acid. It has a role as an antibacterial agent, an anti-inflammatory agent, a human metabolite, a volatile oil component, a plant metabolite and an algal metabolite. It is a straight-chain saturated fatty acid and a medium-chain fatty acid. It is a conjugate acid of a decanoate. It derives from a hydride of a decane.

• 調製方法

  Decanoic acid can be prepared from oxidation of primary alcohol decanol, by using chromium trioxide (CrO₃) oxidant under acidic conditions.
  Neutralization of decanoic acid or saponification of its esters, typically triglycerides, with sodium hydroxide will give sodium decanoate. This salt (CH₃(CH₂)₈COO-Na⁺) is a component of some types of soap.

• 一般的な説明

  White crystalline solid with a rancid odor. Melting point 31.5°C. Soluble in most organic solvents and in dilute nitric acid; non-toxic. Used to make esters for perfumes and fruit flavors and as an intermediate for food-grade additives.

• 空気と水の反応

  Insoluble in water.

• 反応プロフィール

  Capric acid reacts exothermically to neutralize bases. Can react with active metals to form gaseous hydrogen and a metal salt. May absorb enough water from the air and dissolve sufficiently in Capric acid to corrode or dissolve iron, steel, and aluminum parts and containers. Reacts with cyanide salts or solutions of cyanide salts to generate gaseous hydrogen cyanide. Reacts exothermically with diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides to generate flammable and/or toxic gases. Can react with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), to generate flammable and/or toxic gases and heat. Reacts with carbonates and bicarbonates to generate a harmless gas (carbon dioxide). Can be oxidized exothermically by strong oxidizing agents and reduced by strong reducing agents; a wide variety of products is possible. May initiate polymerization reactions or catalyze (increase the rate of) reactions among other materials.

• 健康ハザード

  Harmful if swallowed or inhaled. Material is irritating to tissues of mucous membranes, and upper respiratory tract, eyes and skin.

• 火災危険

  Capric acid is combustible.

• 安全性プロファイル

  Poison by intravenous route. Mutation data reported. A moderate skin irritant. When heated to decomposition it emits acrid smoke and irritating fumes.

• 職業ばく露

  Deconoic acid (fatty acids, saturated, linear, number of C-atoms ≥8 and ≤12, with termi- nating carboxyl group) is a carboxylic acid microbiocide used in cleaning, sanitizing and disinfecting applications for food processors and dairy farmers.

• 輸送方法

  UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required.

• 純化方法

  The acid is best purified by conversion into its methyl ester, b 114.0o/15mm (using excess MeOH, in the presence of H2SO4). The H2SO4 and MeOH are removed, the ester is distilled in vacuo through a 3ft column packed with glass helices. The acid is then obtained from the ester by saponification and vacuum distillation. [Trachtman & Miller J Am Chem Soc 84 4828 1962, Beilstein 2 IV 1041.]

• 不和合性

  An organic carboxylic acid. Keep away from oxidizers, sulfuric acid, caustics, ammonia, aliphatic amines, alkanolamines, isocyanates, alkylene oxides, and epichlorohydrin. Corrosive solution; attacks most common metals. React violently with strong oxidizers, bromine, 90% hydrogen peroxide, phosphorus trichloride, silver powders or dust. Mixture with some silver compounds forms explosive salts of silver oxalate. Incompatible with silver compounds.

• 廃棄物の処理

  Recycle any unused portion of the material for its approved use or return it to the manu- facturer or supplier. Ultimate disposal of the chemical must consider: the material’s impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations .
