Calone, a derivative of 4-methylcatechol, is known in the fragrance industry as "watermelon ketone" for its distinctive odor. [3]The brand of low-temperature coke used as a smokeless fuel Coalite obtains homocatechol from ammoniacal liquor by solvent extraction, distillation and crystallisation.
C 6 H 4 (OH) 2 + XCl 2 → C 6 H 4 (O 2 X) + 2 HCl where X = PCl or POCl; SO 2; CO. Basic solutions of catechol react with iron(III) to give the red [Fe(C 6 H 4 O 2) 3] 3−. Ferric chloride gives a green coloration with the aqueous solution, while the alkaline solution rapidly changes to a green and finally to a black color on exposure to the ...
There are three structural isomers: 1,2-dihydroxybenzene (the ortho isomer) is commonly known as catechol, 1,3-dihydroxybenzene (the meta isomer) is commonly known as resorcinol, and 1,4-dihydroxybenzene (the para isomer) is commonly known as hydroquinone.
The biodegradation of p-Chlorocresol [8] is done in the liver, and then excreted primarily via the kidneys or in smaller amounts through the lungs. In facultative Thauera sp. strain DO, p-Chlorocresol was degraded aerobically either by dehalogenation followed by catechol degradation pathway, or methyl oxidation to 4-chlorobenzoate. [9]
Creosol is a chemical compound with the molecular formula C 8 H 10 O 2. It is one of the components of creosote . Compared with phenol , creosol is a less toxic disinfectant .
Piperonal can be prepared by the oxidative cleavage of isosafrole or by using a multistep sequence from catechol or 1,2-methylenedioxybenzene.Synthesis from the latter chemical is accomplished through a condensation reaction with glyoxylic acid followed by cleaving the resulting α-hydroxy acid with an oxidizing agent.
4-tert-Butylcatechol (TBC) is an organic chemical compound which is a derivative of catechol. [1] TBC is available in the form of a solid crystal flake [ 2 ] and 85% solution in methanol [ 3 ] or water.
C 6 H 4 O 2 BH + HC 2 R → C 6 H 4 O 2 B-CHCHR. The product is a precursor to the Suzuki reaction and is the only borane which stops at the alkene instead of reacting further to the alkane. [3] [4] Catecholborane may be used as a stereoselective reducing agent when converting β-hydroxy ketones to syn 1,3-diols.
