화학적 성질
Colorless to faintly yellow liquid용도
n-Butyl isocyanate is used as an acylatingagent in the Friedel–Crafts reaction to produce amide.정의
ChEBI: An isocyanate having a butyl group attached to the nitrogen.일반 설명
A clear, colorless liquid with a pungent odor. Flash point 68°F. Very toxic by ingestion, and may also be toxic by skin absorption and inhalation. Vapors heavier than air. Less dense than water and insoluble in water. Produces toxic oxides of nitrogen during combustion.공기와 물의 반응
Highly flammable. Extremely slow decomposition by water. Less dense than water and insoluble in water.반응 프로필
Isocyanates and thioisocyanates are incompatible with many classes of compounds, reacting exothermically to release toxic gases. Reactions with amines, aldehydes, alcohols, alkali metals, ketones, mercaptans, strong oxidizers, hydrides, phenols, and peroxides can cause vigorous releases of heat. Acids and bases initiate polymerization reactions in these materials. Some isocyanates react with water to form amines and liberate carbon dioxide. Base-catalysed reactions of isocyanates with alcohols should be carried out in inert solvents. Such reactions in the absence of solvents often occur with explosive violence [Wischmeyer 1969].위험도
Strong irritant to eyes and skin.건강위험
n-Butyl isocyanate exhibits low inhalationtoxicity and relatively higher oral toxicity.This is in contrast to the aromatic isocyanates. The toxic effects are nausea, dyspnea, insomnia, coughing, and chest pain.Such symptoms, however, are much lessmarked than those of methyl isocyanate.LC50 value, inhalation (mice): 680 mg/m3
LD50 value, oral (mice): 150 mg/kg
There is no report of any carcinogenic orteratogenic study of this compound.
화재위험
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapors may travel to source of ignition and flash back. Substance will react with water (some violently) releasing flammable, toxic or corrosive gases and runoff. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water.Safety Profile
A poison by ingestion and intravenous routes. Mddly toxic by inhalation. A powerful irritant to eyes, skin, and mucous membranes. A flammable liquid. See also CYANATES and NITROGEN MONOXIDE.잠재적 노출
N-Butyl isocyanate is used as a reagent in organic synthesis; used as intermediates in production of pharmaceuticals, carbamate and urea insecticides, and fungicides. It is also used in the production of sulfonylurea antidiabetic drugs운송 방법
UN2485 n-Butyl isocyanate, Hazard Class: 6.1; Labels: 6.1—Poison Inhalation Hazard, 3—Flammable liquid. Hazard, Inhalation Hazard Zone B. PGI.비 호환성
Vapor may form explosive mixture with air. Isocyanates are highly flammable and reactive with many compounds, even with themselves. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Reaction with moist air, water or alcohols may form amines and insoluble polyureas and react exothermically, releasing toxic, corrosive or flammable gases, including carbon dioxide; and, at the same time, may generate a violent release of heat increasing the concentration of fumes in the air. Incompatible with amines, aldehydes, alkali metals, ammonia, carboxylic acids, caprolactum, alkaline materials, glycols, ketones, mercaptans, hydrides, organotin catalysts, phenols, strong acids, strong bases, strong reducing agents such as hydrides, urethanes, ureas. Elevated temperatures or contact with acids, bases, tertiary amines, and acylchlorides may cause explosive polymerization. Contact with metals may evolve flammable hydrogen gas. Attacks some plastics, rubber and coatings. May accumulate static electrical charges, and may cause ignition of its vapors폐기물 처리
Dispose of contents and container to an approved waste disposal plant. Use a licensed professional waste disposal service to dispose of this material. Caution: this chemical is highly flammable with a low flash point (,20C). 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.노르말부틸이소시아네이트 준비 용품 및 원자재
