Is p-cresol toxic?
Abstract. Background: Uremic syndrome is the consequence of the retention of solutes usually cleared by the healthy kidneys. p-Cresol can be considered a prototypic protein-bound uremic toxin. It is conceivable, analogous with drugs, that the non-protein-bound fraction of p-cresol exerts toxicity.
Where does p-cresol come from?
p-Cresol is produced by bacterial fermentation of protein in the human large intestine. It is excreted in the feces and urine, and is a component of human sweat that is attractive to female mosquitoes. p-Cresol is a constituent of tobacco smoke.
How do you get p-cresol from phenol?
Phenols when treated with alkyl halides in presence of anhydrous AlCl3, undergoes Friedel-Crafts Reaction to form alkyl substituted phenols i.e majorly p-cresol in which -CH3 group is in p-position of phenol.
Does p-cresol dissolve in water?

Is cresol a carcinogen?
EPA has classified o-cresol, m-cresol, and p-cresol as Group C, possible human carcinogens.
How do you make p-cresol?
Industrially, p-cresol is currently prepared mainly by a two-step route beginning with the sulfonation of toluene: CH3C6H5 + H2SO4 → CH3C6H4SO3H + H2O. Basic hydrolysis of the sulfonate salt gives the sodium salt of the cresol: CH3C6H4SO3H + 2 NaOH → CH3C6H4OH + Na2SO3 + H2O.
Where does p cresol come from?
How are the following compounds are obtained from phenol phenolphthalein?
Phenol is heated with phthalic anhydride in the presence of conc. H2SO4 to give phenolphthalein. Was this answer helpful?
Is p-cresol an acid or base?
When an electron withdrawing nitro group is present in para position to the −OH group, due to phenoxide ion stabilisation, the acidity is increased. Therefore, the most acidic element is p-nitrophenol. Of meta, ortho, and para isomers, cresol is a methyl phenol.
What is soap solution?
Soaps are water-soluble sodium or potassium salts of fatty acids. The process is termed saponification reaction in which a strong base is warmed with a fatty acid or fat ( or oils) to yield a salt and an alkanol which is mostly glycerine( or glycerol).

What is a cresol compound?
Cresols (also hydroxytoluene) are a group of aromatic organic compounds. They are widely-occurring phenols (sometimes called phenolics) which may be either natural or manufactured. They are also categorized as methyl phenols.

What is p-cresol made of?
This residue contains a few percent by weight of phenol and cresols. Industrially, p -cresol is currently prepared mainly by a two-step route beginning with the sulfonation of toluene:
How do you convert sulfonate to p cresol?
Basic hydrolysis of the sulfonate salt gives the sodium salt of the cresol: 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.
