Carbonation is the chemical reaction of carbon dioxide to give carbonates, bicarbonates, and carbonic acid. [1] In chemistry, the term is sometimes used in place of carboxylation, which refers to the formation of carboxylic acids.
Carbonatation induced rebar corrosion. Carbonatation is a slow process that occurs in concrete where lime (CaO, or Ca(OH) 2 ) in the cement reacts with carbon dioxide (CO 2) from the air and forms calcium carbonate. The water in the pores of Portland cement concrete is normally alkaline with a pH in the range of 12.5 to 13.5.
Carbonated water [a] is water containing dissolved carbon dioxide gas, either artificially injected under pressure, or occurring due to natural geological processes. ...
This form of weathering is called carbonation and carbonatation. In medicine, calcium bicarbonate is sometimes administered intravenously to immediately correct the cardiac depressor effects of hyperkalemia by increasing calcium concentration in serum, and at the same time, correcting the acid usually present.
A series of processes that involve carbonization. [2]Carbonization is a pyrolytic reaction, therefore, is considered a complex process in which many reactions take place concurrently such as dehydrogenation, condensation, hydrogen transfer and isomerization.
Carboxylation is a chemical reaction in which a carboxylic acid is produced by treating a substrate with carbon dioxide. [1] The opposite reaction is decarboxylation.In chemistry, the term carbonation is sometimes used synonymously with carboxylation, especially when applied to the reaction of carbanionic reagents with CO 2.
Carbonatation, sometimes called carbonation, is the formation of calcium carbonate (CaCO 3) by chemical reaction, which, if used in concrete, can sequester carbon dioxide. [27] The speed of carbonation depends primarily on the porosity of the concrete and its moisture content.
The steps commonly used for beet are carbonatation and sulphonation. Carbonatation uses milk of lime, an alkaline liquid produced from calcium hydroxide, together with carbon dioxide (the exhaust from the lime kiln that produces the lime) to precipitate impurities into a form that can be removed from the raw juice. In the carbonation step ...
