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 .
Catechol (/ ˈ k æ t ɪ tʃ ɒ l / or / ˈ k æ t ɪ k ɒ l /), also known as pyrocatechol or 1,2-dihydroxybenzene, is an organic compound with the molecular formula C 6 H 4 (OH) 2. It is the ortho isomer of the three isomeric benzenediols .
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. [1]

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.
3-Methylcatechol is an organic compound with the formula CH 3 C 6 H 3 (OH) 2 A white solid, it is one of the isomers of methylbenzenediol. Being structurally related to lignans , it is contributes to the aerosol generate by combustion of wood.
ch 3 c 6 h 4 so 3 h + 2 naoh → ch 3 c 6 h 4 oh + na 2 so 3 + h 2 o Other methods for the production of p -cresol include chlorination of toluene followed by hydrolysis. In the cymene-cresol process, toluene is alkylated with propene to give p -cymene , which can be oxidatively dealkylated in a manner similar to the cumene process .
