Mechanism is also proposed for the decarboxylation of salicylic acid in benzoic acid solutionA competition between an oxygen atom and the terminal ring carbon atom for the proton to give either the undissociated acid or a sigmacomplex leading to products is shown by eq.

Aug 31 2021nbsp018332Decarboxylative C−C and Cheteroatom bond formation of benzoic acids have mostly been achieved by transitionmetalmediated or catalyzed thermal decarboxylative carbometalation to generate arylmetal intermediates for reductive elimination with versatile coupling partners.
Benzoic acid can directly produce benzeneThis process is called pyrolysisThe term pyro means heat or high temperature and lysis means break or decomposeThe decarboxylation of sodium benzoate in the presence of soda lime occurs at lower temperaturesBenzoic acid can also produce benzene by decarboxylation reaction.
Benzoic acid is a colorless solid poorly soluble in water but more soluble in organic solvents.
Benzoic acid is used in a number of daily activities and is a very commonly seen product in many industrial as well as household applicationsThe structure of benzoic acid is a carboxyl group attached to a ring of benzeneIt is usually denoted using the formula C6H5COOHIt contains an aromatic ring and therefore is also referred to as aromatic benzoic acidAs can probably be understood from this this is also the reason why this compound has a certain pleasant smell.

Decarboxylation of Benzoic AcidDecarboxylation is the removal of carbon dioxide as sodium carbonate Na 2 CO 3 by treating the sodium salt of benzoic acid sodium benzoate using soda lime mixture of NaOH amp CaO to form benzene.
Higher purity benzoic acid can be purchased from chemical suppliers or more convenient from eBay or Amazon.
It has the formula C7H6O2 though its more conveniently written as C6H5COOHIt is also sometimes abbreviated as PhCOOH.

Radical decarboxylation of benzoic acids has been successfully used to react with reactive radical acceptors such as heteroarenes21 acrylates or diboron species22 but not to make C O bonds even with prior activation to activated esters.
Sep 02 2021nbsp018332Oxidative decarboxylation of benzoic acid between 300−400 176C gives phenolIf CuII salts are used the reaction can proceed at lower temperatures around 200 176C C 6 H 5 COOH 189 O 2 → C 6 H 5 OH CO 2Decarboxylation of benzoic acid or its salts will yield benzene.
The carboxyl group present in benzoic acid is acidic in nature and thus reacts with base compounds such as sodium hydroxide to produce a salt known as sodium benzoate as per the neutralisation reactionWhen sodium benzoate is treated with an acid such as hydrochloric acid then benzoic acid is formed back.
The decarboxylation of phthalic acids was studied with Bacillus spStrain FO a marine mixed culture ON7 and Pseudomonas testosteroniThe mixed culture ON7 when grown anaerobically on phthalate but incubated aerobically with chloramphenicol quantitatively converted phthalic acid to benzoic acid.
The oxidation of benzoic acid are shown in Scheme 1The oxidized benzoic acid can exist as three forms peroxy acid R1 arene oxide R2 and hydrogen carbonate R3.
The positive results indicated that the loss of radioactivity from labelled benzoic acid was due to decarboxylation of the acidThe radioactivity of the trapped CO was approximately equal to that lost by the benzoiccarboxyl Cu acid in the nutrient mediumDecarboxylation of Benzoic Acid by Hypoxylon pruinatum 23.
This reaction can be done with certain carboxylic acids themselvesFor example benzene can be made by heating soda lime with solid benzoic acid benzenecarboxylic acid C 6 H 5 COOHYou can think of this as first a reaction between the acid and the soda lime to make sodium benzoate and then a decarboxylation as in the first example.
When benzoic acid C₆H₅COOH is reacted with Soda lime solution NaOH in Ca OH₂ decarboxylation reaction takes place with the removal of Na₂CO₃ and the resultant product which is formed will be benzene moleculeThe reaction can be written asC₆H₅COOH 2NaOH → C₆H₅ Na₂CO₃This reaction is called soda lime reaction.
