化学的特性
Butyl propionate is a flammable, colorless to
straw-yellow liquid with an apple-like odor.
天然物の起源
Reported found in fresh apple, apple juice, melon, strawberry, Gruyere de Comte cheese and plum.
使用
Butyl propionate is a moderately fast evaporating solvent. Its linear structure contributes to effective viscosity reduction and improves solvent diffusion from coating films.
Butyl propionate is used solvent for nitrocellulose, retarder in lacquer thinner, ingredient of perfumes, flavors.
製造方法
By esterification of propionic acid with n-butyl alcohol in the presence of concentrated H2SO4 or p-toluene sulfonic acid.
一般的な説明
A water-white liquid with an apple-like odor. Less dense than water. Flash point 90°F. May irritate skin and eyes. Used to make perfumes and flavorings.
空気と水の反応
Highly flammable. Very slightly soluble in water.
反応プロフィール
BUTYL PROPIONATE 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.
危険性
Skin and eye irritant. Flammable, moderate
fire risk.
健康ハザード
Contact will cause eye and skin irritation. Vapor exposure may cause eye and respiratory tract irritation.
火災危険
Special Hazards of Combustion Products: Irritating and toxic gases, such as carbon dioxide and carbon monoxide, may be produced in fire.
安全性プロファイル
Mildly toxic by
ingestion. A skin irritant. Dangerously
flammable when exposed to heat or flame.
To fight fire, use foam, CO2, dry chemical.
Incompatible with oxidizing materials. See
also ESTERS, n-BUTYL ALCOHOL, and
PROPIONIC ACID.
職業ばく露
It is used as a solvent or lacquer thinner; and in perfumes and flavoring
輸送方法
UN1914 Butyl propionates, Hazard Class: 3;
Labels: 3—Flammable liquid
不和合性
Vapor 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. May accumulate static electrical
charges and cause ignition of its vapors.
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.
