説明

Propionaldehyde is a volatile liquid substance which consists of one carbonyl group and its characteristic functional group. The main functional group is an aldehyde which classifies propionaldehyde in the carbonyls. The main trunk of this substance is a short aliphatic chain. The carbonyl group determines, to a large extent, its chemical properties and most importantly its nucleophilic property. Propionaldehyde is readily oxidized if in contact to oxygen and should therefore be stored under inert gases.

化学的特性

Propionaldehyde has a characteristic sharp and pungent odor similar to acetaldehyde.It undergoes reactions typical for the low molecular weight aldehydes, which, because of the terminal carbonyl group, are very reactive. Contamination or the exposure to elevated temperatures may induce a hazardous polymerization.
Propionaldehyde
Propionaldehyde is a colorless, flammable liquid with a suffocating fruity odor. It is used as Intermediate for the chemical industry, for example for the manufacture of pharmaceuticals, pesticides, perfumes and plastics.

天然物の起源

Reported found in apple aroma and in the essential oils of camphor, Rosa centifolia, clary sage, Pinus excelsa and Pinus silverstris. Also reported found in over 100 natural products including apple, banana, sweet cherry, sour cherry, black currant grapes, melon, pineapple, strawberry, cabbage, carrot, celery, cucumber, garlic, onion, leek, potato, peas, rutabaga, tomato, Scotch spearmint oil, vinegar, bread and bread preferment, blue cheeses, cheddar cheese, Swiss cheese, butter, milk, cream, boiled egg, caviar, fatty fish, cooked turkey, beef, pork and chicken, beer, rum, cognac, whiskies, grape wines, coffee, cocoa, tea, roasted filberts and peanuts, peanut oil, potato chips, pecans, oats, honey, soybeans, Arctic bramble, beans, Bantu beer, plum brandy, cauliflower, Brussels sprouts, rice, prickly pear, peated malt, clary sage, truffle, krill, oysters, loganberry, Chinese quince and maté.

使用

Propionaldehyde is produced by the oxo reaction of ethylene with carbon monoxide and hydrogen. n-Propyl alcohol is produced by hydrogenation of propionaldehyde, and propionic acid is made by oxidation of propionaldehyde.
n-Propyl alcohol is used as solvent in printing inks and as an intermediate in the preparation of agricultural chemicals. Propionic acid is used as a grain preservative as, for example, in preventing spoilage of wet corn used as animal feed. The use of propionic acid as a grain preservative is an alterna tive to drying by heating, which consumes fuel, and is considered mostly when fuel is expensive.

使用

Propionaldehyde is used in the productionof propionic acid, propionic anhydride, andmany other compounds. It is formed in theoxidative deterioration of corn products, suchas corn chips. It occurs in automobile exhaustgases.

使用

Manufacture of propionic acid, polyvinyl, and other plastics; synthesis of rubber chemicals; disin- fectant; preservative.

定義

ChEBI: An aldehyde that consists of ethane bearing a formyl substituent. The parent of the class of propanals.

製造方法

By oxidation of propyl alcohol, or by dry distillation of barium propionate with calcium formate.

製造方法

Propionaldehyde is prepared in the usual way by the oxidation of n-propyl alcohol. It can also be prepared by dehydrogenating the alcohol by passing the vapors over a heated copper or brass catalyst. This avoids the danger of further oxidation to propionic acid.
The reactions of propionaldehyde are practically like those of acetaldehyde. It must be remembered that only the two alpha hydrogen atoms are active in replacement and condensation reactions.

一般的な説明

A clear colorless liquid with an overpowering fruity-like odor. Less dense than water. Flash point 15°F. Vapors are heavier than air.

空気と水の反応

Highly flammable. Soluble in water.

反応プロフィール

Propionaldehyde may form explosive peroxides. Reacts vigorously with oxidizing agents. Explosive in the form of vapor when exposed to heat or flame [Lewis]. Incompatible with strong bases and strong reducing agents. Vigorous polymerization reaction with methyl methacrylate. Polymerization may also occur in the presence of acids or caustics .

危険性

Flammable, dangerous fire risk, explosive limits in air 3.0–16%. Upper respiratory tract irri- tant.

健康ハザード

Propionaldehyde is a mild irritant to humanskin and eyes. The irritation effect from40 mg was severe in rabbits’ eyes. The toxicityof this compound observed in test animalswas low. Subcutaneous administration in ratsexhibited the symptoms of general anestheticeffect, convulsion, and seizure. Inhalationtoxicity was determined to be low. A concentrationof 8000 ppm (19,000 mg/m3) inair was lethal to rats.
LD50 value, oral (rats): 1400 mg/kg
LD50 subcutaneous (rats): 820 mg/kg.

火災危険

Behavior in Fire: Vapor is heavier than air and may travel considerable distance to a source of ignition and flash back.

安全性プロファイル

Moderately toxic by skin contact, ingestion, and subcutaneous routes. Mddly toxic by inhalation. A skin and severe eye irritant. Flammable liquid. Dangerous fire hazard when exposed to heat or flame; reacts vigorously with oxidizers. Explosive in the form of vapor when exposed to heat or flame. Vigorous polymerization reaction with methyl methacrylate. To fight fire, use alcohol foam, CO2, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes. See also ALDEHYDES.

職業ばく露

Used as a synthetic flavoring; as a disinfectant and preservative; to make propionic acid; in plastic and rubber manufacturing; to make alkyl resins and plasticizers.

Carcinogenicity

In a mutagenic test in V79 cells, Eder et al. observed that propionaldehyde is not mutagenic at 1 mM, but is toxic at 2mM. Similar to acrolein, Eder et al. suggested that the mutagenicity of this compound is mediated by its bifunctionality, whereas its cytotoxicity is mediated by the aldehyde function.

輸送方法

UN1275 Propionaldehyde, Hazard Class: 3; Labels: 3-Flammable liquid.
Propionaldehyde is readily oxidized if in contact to oxygen and should therefore be stored under inert gases.

純化方法

the aldehyde with CaSO4 or CaCl2, and fractionally distil it under nitrogen or in the presence of a trace of hydroquinone (to retard oxidation). Blacet and Pitts [J Am Chem Soc 74 3382 1952] repeatedly distilled the middle fraction in a vacuum until it no longer gave a solid polymer when cooled to -80o. It is stored with CaSO4. [Beilstein 1 IV 3165.]

不和合性

Incompatible with strong acids; amines. 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, oxoa- cids, epoxides. Strong caustics; reducing agents can cause explosive polymerization. Can self-ignite if finely dispersed on porous or combustible material, such as fabric. Heat or UV light can cause decomposition. Aldehydes are fre- quently involved in self-condensation or polymerization reactions. These reactions are exothermic; they are often catalyzed by acid. Aldehydes are readily oxidized to give carboxylic acids. Flammable and/or toxic gases are gener- ated by the combination of aldehydes with azo, diazo com- pounds, dithiocarbamates, nitrides, and strong reducing agents. Aldehydes can react with air to give first peroxo acids, and ultimately carboxylic acids. These autoxidation reactions are activated by light, catalyzed by salts of transition metals, and are autocatalytic (catalyzed by the products of the reaction). The addition of stabilizers (anti- oxidants) to shipments of aldehydes retards autoxidation

廃棄物の処理

Propionaldehyde is destroyed by burning in achemical incinerator equipped with an afterburnerand scrubber. Permanganate oxidationis a suitable laboratory method of destruction.
