Is mesitylene soluble in water?
1,3,5-trimethylbenzene appears as a colorless liquid with a peculiar odor. Insoluble in water and less dense than water.
What is mesitylene used for?
Potential Exposure. Mesitylene is used as raw material in chemical synthesis and as ultraviolet stabilizer; as a paint thinner, solvent, and motor fuel component; as an intermediate in organic chemical manufacture.

Mesitylene/Formula
Is mesitylene polar or nonpolar?
almost vanish when p-xylene and mesitylene are used as non-polar components in the mixture (Figs 2, 3, 5 and 6).
How do you convert mesitylene to acetone?
According to Chang (1977), with HZSM-5, acetone undergoes classic acid- catalyzed condensation to mesitylene (also called aldol condensation), which occurs when acetone contacts any acid. For example, when acetone contacts sulfuric acid for a long time, it forms an aldol.
How many NMR signal you will set for mesitylene?
All 3 methyl groups (9 hydrogens) are equivalently split and gives a signal at 2.26 as singlet. So totally there are 2 signals given by the mesitylene molecule.
What is the boiling point of mesitylene?
328.5°F (164.7°C)
Mesitylene/Boiling point
Is trimethylbenzene a carcinogen?
Under the current U.S. EPA (2005) cancer guidelines, the human and animal data are inadequate for a determination of the human carcinogenic potential of 1,2,4-trimethylbenzene. There are no appropriate human or animal data from which to derive an inhalation unit risk for 1,2,4- trimethylbenzene.
What is the density of mesitylene?
864 kg/m³
Mesitylene/Density
Which Cannot show aldol condensation?
The carbonyl compounds must contain an α− hydrogen atom to undergo aldol condensation. Thus, propanal and ethanal are the aldehydes that can undergo aldol condensation. Thus, aldehydes that do not undergo aldol condensation are trichloroethanal, benzaldehyde and methanal.
What happens when chloroform is treated with acetone?
Chloroform combines with acetone in the presence of potassium hydroxide to give chloretone, which is used as a sleep producing (hypnotic) drug.
How do you prepare mesitylene from xylene?
Mesitylene is prepared by equilibration of xylene (or simple methyl alkylation of it) over solid acid catalyst: Trimerization of acetone via aldol condensation, which is catalyzed and dehydrated by sulfuric acid affords a mixture of 1,3,5- and 1,2,4-trimethylbenzenes. Oxidation of mesitylene with nitric acid affords trimesic acid, C 6 H 3 (COOH) 3.
What is the chemical name of mesitylene?
Mesitylene. Mesitylene is a colourless liquid with sweet aromatic odor. It is a component of coal tar, which is its traditional source. It is a precursor to diverse fine chemicals. The mesityl group (Mes) is a substituent with the formula C 6 H 2 Me 3 and is found in various other compounds.
What is the difference between 1 3 5 trimethylbenzene and mesitylene?
1,3,5-trimethylbenzene is a trimethylbenzene carrying methyl substituents at positions 1, 3 and 5. Mesitylene or 1, 3, 5-trimethylbenzene is a derivative of benzene with three methyl substituents symmetrically placed on the ring.
What is the 1H NMR spectrum of mesitylene?
The three aromatic hydrogen atoms of mesitylene are in identical chemical shift environments. Therefore, they only give a single peak near 6.8 ppm in the 1H NMR spectrum; the same is also true for the nine methyl protons, which give a singlet near 2.3 ppm.
