化学的特性
Propyl formate has a characteristic fruity (rum–plum) odor and a corresponding bittersweet flavor.
天然物の起源
Reported found in plum, brandy, apple, black currant, and pineapple.
使用
Propyl formate was used in the synthesis of the radicals - CH
3CH
2CHOCHO, CH
3CHCH
2OCHO, and CH
2CH

3.H
2O
2 radical-generating method.
製造方法
By action of sulfuric acid on a mixture of propyl alcohol, formic acid and sodium formate; also by distilling propyl alcohol
with anhydrous formic acid in the presence of sodium formate.
一般的な説明
A clear colorless liquid with a pleasant odor. Flash point 27°F. Slightly soluble in water and less dense than water. Hence floats on water. Vapors are heavier than air.
空気と水の反応
Highly flammable. Slightly soluble in water.
反応プロフィール
PROPYL FORMATES are esters. React with acids to liberate heat along with propanols and formic acid. Strong oxidizing acids may cause a reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by interaction with caustic solutions. Flammable hydrogen is generated by mixing with alkali metals and hydrides.
危険性
Flammable, dangerous fire risk.
健康ハザード
May cause toxic effects if inhaled or absorbed through skin. Inhalation or contact with material may irritate or burn skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.
火災危険
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
安全性プロファイル
Moderately toxic by
ingestion. An irritant to skin, eyes, and
mucous membranes. Narcotic in high
concentration. Dangerous fire hazard when
exposed to heat, flame, or oxidizers. Ignites
on contact with potassium-tert-butoxide.
Explosive in the form of vapor when
exposed to heat or flame. To fight fire, use
alcohol foam. When heated to
decomposition it emits acrid smoke and
irritating fumes. See also ESTERS.
純化方法
Distil the formate, then wash it with saturated aqueous NaCl, and with saturated aqueous NaHCO3 in the presence of solid NaCl, dry it with MgSO4 and fractionally distil it. [Beilstein 2 IV 26.]
