Tiglic acid

티그릭 산 C화학적 특성, 용도, 생산

개요

frarc.s-2-Methyl-2-butenoic acid has a sweet, warm, spicy odor. May be synthesized from 2-hydroxy-2-methylbutyronitrile.

화학적 성질

WHITE TO BEIGE CRYSTALLINE POWDER AND CHUNKS

출처

Reported found in celery leaves and stalk, cocoa, mango, dried bonito and Roman chamomile oil

용도

Tiglic acid is the stable isomer of angelic acid. Tiglic acid was found as glyceride in croton oil, as butyl ester in the oil of the Roman camomile, and as geranyl tiglate in oil of geranium. Tiglic a cid is formed during the charcoaling of maple wood.

정의

ChEBI: A 2-methylbut-2-enoic acid having its double bond in trans-configuration.

일반 설명

A white lustrous flaked solid with a fruity or spicy odor. About the same density as water and slightly soluble in water. May burn if heated to high temperatures. May severely irritate skin, eyes, lungs or mucous membranes.

공기와 물의 반응

Slightly soluble in water.

반응 프로필

TIGLIC ACID is a carboxylic acid. Carboxylic acids donate hydrogen ions if a base is present to accept them. They react in this way with all bases, both organic (for example, the amines) and inorganic. Their reactions with bases, called "neutralizations", are accompanied by the evolution of substantial amounts of heat. Neutralization between an acid and a base produces water plus a salt. Carboxylic acids in aqueous solution and liquid or molten carboxylic acids can react with active metals to form gaseous hydrogen and a metal salt. Such reactions occur in principle for solid carboxylic acids as well, but are slow if the solid acid remains dry. Even "insoluble" carboxylic acids may absorb enough water from the air and dissolve sufficiently in Tiglic acid to corrode or dissolve iron, steel, and aluminum parts and containers. Carboxylic acids, like other acids, react with cyanide salts to generate gaseous hydrogen cyanide. The reaction is slower for dry, solid carboxylic acids. Insoluble carboxylic acids react with solutions of cyanides to cause the release of gaseous hydrogen cyanide. Flammable and/or toxic gases and heat are generated by the reaction of carboxylic acids with diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides. Carboxylic acids, especially in aqueous solution, also react with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), to generate flammable and/or toxic gases and heat. Their reaction with carbonates and bicarbonates generates a harmless gas (carbon dioxide) but still heat. Like other organic compounds, carboxylic acids can be oxidized by strong oxidizing agents and reduced by strong reducing agents. These reactions generate heat. A wide variety of products is possible. Like other acids, carboxylic acids may initiate polymerization reactions; like other acids, they often catalyze (increase the rate of) chemical reactions.

건강위험

TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.

화재위험

Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.

Safety Profile

Low toxicity by ingestion and skin contact. A severe skin irritant. When heated to decomposition it emits acrid smoke and irritating fumes.

Purification Methods

Crystallise it from water. It is steam volatile and is soluble in organic solvents. [Beilstein 2 IV 1552.]
