(1931) The conjugation of benzoic acid in the urine.
Some 60 - 75% of absorbed toluene is metabolized to benzoic acid by the microsomal mixed-function oxidase system, with subsequent conjugation with glycine to form hippuric acid.
[IF NO precipitate forms, then likely some ether is present on the surface of yourbenzoic acid solution. Gently blow off the ether on the acidified solution until crystalsappear. Continue to cool in ice bath until precipitation is complete.]
Benzoic acid - New World Encyclopedia
In rats, rabbits, and man, approximately 20% of the dose is excreted unchanged via the lungs, while approximately 80% is converted to benzoic acid and excreted in the urine unchanged or as its glycine conjugate, hippuric acid.
Oral The initial step in the metabolic transformation of toluene to benzoic acid, after oral administration, appears to be hydroxylation of toluene to benzyl alcohol (Fig.
How to convert benzene into benzoic acid - Quora
(1969) Species differences in the albumin binding of 2,4,6-trinitrobenzaldehyde, chlorphenoxyacetic acids, 2-(4'-hydroxybenzeneazo) benzoic acid and some other drugs; the unique behaviour of rat albumin.
(1965) Influence of X-radiation on development of enzymes responsible for desulfuration of an organic phosphorothioate and reduction of p-nitrobenzoic acid in the livers of male rats.

How can you convert benzene into benzoic acid
Furthermore, toluene is used as a raw material in the organic synthesis of a large number of chemicals such as toluene diisocyanate, benzoic acid, benzaldehyde, xylene, toluene-sulfonylchloride (the o-isomer is converted to saccharin), other derivatives of toluene used as dye intermediates, resin modifiers, germicides, etc.
How would you convert Benzoic acid into Bromobenzene in one step
No effects of the pretreatment was observed on the rates of oxidation of aromatic alcohol to the corresponding acid, phenolic sulfatation, or on the glucuronidation or glycine conjugation of benzoic acid.
How can the synthesis of benzoic acid …
Sufficient data are not available to give an opinion about the measurement of other metabolites such as benzoic acid or o-cresolin urine to estimate exposure to toluene in the air.
* 122.12 g/mol = 0.814g benzoic acid
The maximum rate of transformation of benzoic acid to hippuric acid seemed to be limited by the availability of glycine (Quick, 1931; Amsel & Levy, 1969).
the 122.12 g/mol is the molar mass of benzoic acid
Biological monitoring of toluene exposure A number of biological tests have been investigated for evaluating human exposure to toluene: toluene in expired air and/or in blood and human breast milk; hippuric acid in urine and/or blood; and benzoic acid, and o-cresol in urine (section 7.4).
you could oxidize benzaldehyde to benzoic acid
Riihimaki (1979) studied the possible kinetic interactions between toluene and xylene and their metabolites and found that full conjugation capacity with benzoic acid and methylbenzoic acid was reduced during inhalation of toluene and/or xylene.
Grignard Reaction: Benzoic Acid Kenneth ..
Collect the precipitate by vacuum filtration. Dry the product as thoroughly aspossible, weigh it, and recrystallize it from hot water. (The ether layer contains neutralnon-polar compounds such as unreacted bromobenzene and biphenyl. It should be discardedinto the ORGANIC WASTE bottle.) Calculate the yield of benzoic acid. Take a sample of therecrystallized material and determine its melting point. (Place the remainder of yourbenzoic acid in the jar provided.)
