What is the formula for 1,2,4-trimethylbenzene?
C9H121,2,4-Trimethylbenzene / Formula
What is trimethylbenzene used for?
In addition to being part of the compound used as a gasoline additive, 1,2,4-trimethylbenzene is also used as a solvent, as a paint and lacquer thinner, in making dyes and in producing prescription drugs.

Is trimethylbenzene a benzene?
The trimethylbenzenes constitute a group of substances of aromatic hydrocarbons, which structure consists of a benzene ring with three methyl groups (–CH3) as a substituent. Through their different arrangement, they form three structural isomers with the molecular formula C9H12.
Is trimethylbenzene flammable?
ICSC 1433 – 1,2,4-TRIMETHYLBENZENE. Flammable. Above 44°C explosive vapour/air mixtures may be formed. NO open flames, NO sparks and NO smoking.
Is trimethylbenzene the same as benzene?
Is trimethylbenzene soluble in water?
1,2,4-trimethylbenzene appears as a liquid. Flash point near 130°F. Less dense than water and insoluble in water.
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 do you distill Mesitylene?
The crystals are mixed with 2 l. of 15 per cent hydrochloric acid and heated under a reflux condenser for two to three hours. The reaction mixture is now steam distilled, the mesitylene separated, dried over calcium chloride and fractionated; the portion which boils at 163–167° is collected.
How do you cook Mesitylene?
Mesitylene is prepared by transalkylation of xylene over solid acid catalyst: 2 C6H4(CH3)2 ⇌ C6H3(CH3)3 + C6H5CH. C6H4(CH3)2 + CH3OH → C6H3(CH3)3 + H2O. 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.
How do you convert Mesitylene to acetone?
How is Mesitylene manufactured?
Mesitylene can be prepared by the action of sulfuric acid1 on acetone; by the action of hydrochloric acid on acetone, under pressure and at temperatures varying from 100 to 200°;2 by the condensation of acetone using silica gel or alumina as a catalyst;3 and by the methylation of benzene, toluene, or m-xylene.
What is mesitylene formula?
