Does acetic acid absorb UV light?
Acetic acid has a typical concentration in beers (57-145 mg/L), and its aqueous solutions have a characteristic UV-spectrum from 180 to 260 nm.
What is the PK value of p-cresol?

Which is more acidic p-cresol or m cresol?
m-cresol is more acidic compared to p-cresol. The classic explanation of the cresol is that a methyl should provide a positive inductive effect (which is +I) to the ring. They increase the negative charge on phenolate oxygen, consequently making all the cresols less acidic compared to phenol.
What is the pH of p-cresol?
Printed in U.S.A. Rate constants for the reaction between horseradish peroxidase compound I and p-cresol have been determined at several values of pH between 2.98 and 10.81.
Is P-cresol toxic?
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.
Which is more acidic cresol?
Phenol is a stronger acid than cresol. This is because in cresol CH3 is an electron-donating group which increases the electron density on the oxygen.
What is the use of cresol?
Mixtures of cresols are used as solvents for synthetic resin coatings such as wire enamels, metal degreasers, cutting oils, and agents to remove carbon deposits from combustion engines. Other uses of cresol mixtures include ore flotation and fiber treatment.
Is P-cresol and alcohol?
It is a colourless solid that is widely used intermediate in the production of other chemicals. It is a derivative of phenol and is an isomer of o-cresol and m-cresol….p-Cresol.

What kind of odor does p-cresol have?
P-cresol is a colorless solid with a tar like odor. Sinks and mixes slowly with water. (USCG, 1999)

How is p-cresol metabolized in the body?
It is a partially lipophilic moiety which strongly binds to plasma protein (close to 100%) under normal conditions. p-Cresol is metabolized through conjugation, mainly sulphation and glucuronization, but removal of the unconjugated p-cresol is, at least in part, via the urine.
How much p cresol is in 100 ml water?
2.5 g in 100 mL water at 50 °C; 5.0 g in 100 mL water at 100 °C. Soluble in aqueous alkali hydroxides. Souble in organic solvents.
