टोल्यूनि इसके अंग्रेजी अर्थ का उदाहरण

2- and 4-Chlorotoluene are precursors to the corresponding benzyl chloride (ClC6H4CH2Cl), benzaldehyde (ClC6H4CHO), and benzoyl chloride (ClC6H4C(O)Cl).

The primary route of toluene metabolism is by [to Kristie Davis (née Stenglein, later Marano) (born January 24, 1979) is an Olympic wrestler from Albany, New York.

A common example is the removal of water generated during a reaction in boiling toluene.

The reaction can be carried out in enantiomeric excess of up to 90% with the aid of bifunctional chiral BINOL and phosphinyl BINOL compounds, for example in the reaction of n-(4-chloro-benzylidene)-benzenesulfonamide with methyl vinyl ketone (MVK) in cyclopentyl methyl ether and toluene at -15°C.

The amino acid sarcosine reacts with paraformaldehyde when heated at reflux in toluene to an ylide which reacts with a double bond in a 6,6 ring position in a fullerene via a 1,3-dipolar cycloaddition to yield a N-methylpyrrolidine derivative or pyrrolidinofullerene or pyrrolidino1,2 [60]fullerene in 82% yield based on C60 conversion.

In 1841, Henri Étienne Sainte-Claire Deville isolated toluene by the dry distillation of tolu balsam.

Sulfonation occurs on the side chains, not on the aromatic ring like in p-toluenesulfonic acid.

Industrially, p-cresol is currently prepared mainly by a two-step route beginning with the sulfonation of toluene:.

Other methods for the production of p-cresol include chlorination of toluene followed by hydrolysis.

The amine is mixed with the carbonyl substrate using either dioxane or toluene as a solvent at 90"nbsp;°C for 10 minutes.

This reaction has been catalyzed by trifluoroacetic acid, toluenesulfonic acid, iodine, and Lewis acids.

An example of positive solvatochromism is provided by 4,4'-bis(dimethylamino)fuchsone, which is orange in toluene, red in acetone.

An azeotropic mixture of toluene and water distills out of the reaction, but only the toluene (density 0.

The cogenerated water is removed by azeotropic distillation using toluene or chlorobenzene).
