Krotonik asit bir karboksilik asittir.
Crotonic acid Properties Melting point: Crystalline or crystalline granules or flakes Physical State: Store at room temperature Melting Point: Crotonic acid is a carboxylic acid. Carboxylic acids karbksilik 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 with six or fewer carbon atoms are freely or moderately soluble in water; those with more than six carbons are slightly soluble in water. Soluble carboxylic acid dissociate karboisilik an extent in water to yield hydrogen ions.
The pH of solutions of carboxylic acids is therefore less than 7. Many insoluble carboxylic acids react rapidly with aqueous solutions containing a chemical base and dissolve as the neutralization generates a soluble 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 Crotonic acid to corrode or dissolve iron, steel, and aluminum parts and containers.
Carboxylic acids, like other acids, react with cyanide astiler 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. 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.
Even “insoluble” carboxylic acids may absorb enough water from the air asitper dissolve sufficiently in it to corrode or dissolve iron, steel, and aluminum parts and containers. Crotonic acid is so named because it was erroneously thought to be a saponification product of croton oil.
It crystallizes as needles from hot water. Water extracts from the carrot karboksilok Daucus carota L. Perfekcja exhibit plant growth inhibitory properties against cress, cucumber, onion and carrot in a dose-dependant manner.

This property results from the action of low-and high-molecular components of the extract. The low-molecular component was identified as crotonic acid E butenoic acid. Its presence was also confirmed in other late varieties of carrot. The determined strong herbicidal properties of crotonic acid and its availability after karbokailik to soil combined with its high level in seeds suggest that it might be considered as an allelopathic and autotoxic factor in the seeds.
It is a moisture-sensitive adhesive and is used to give finishing effects in the textile karnoksilik hat industries.

This chemical also appears under: The substance may polymerize under the influence of UV-light karbokxilik moisture. The solution in water is a weak acid. Reacts violently with basesoxidantsreducing agents. The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. The substance is corrosive to the eyes, the skin and the respiratory tract. Inhalation of the vapour may cause lung oedema see Notes. The effects may be delayed.
