Description of 5-dimethyltoluene

• Mesitylene or 1,3,5-trimethylbenzene is a derivative of benzene with three methyl substituents symmetrically placed on the ring. The other two isomeric trimethylbenzenes are 1,2,4-trimethylbenzene (pseudocumene) and 1,2,3-trimethylbenzene (hemimellitene). All three compounds have the formula C6H3(CH3)3, which is commonly abbreviated C6H3Me3. 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 C6H2Me3 and is found in various other compounds.

What is Mesitylene ?

• With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is  Mesitylene   which has developed particularly rapidly in recent years. Do you know about  Mesitylene?
• The official answer：The molecular structure of homo-trimethylbenzene (also known as 1,3,5-trimethyl benzene, molecular formula C9H12) is a functional group that exists in many organic compounds, with the C atoms of the benzene ring forming σ bonds with sp2 hybrid orbitals and the other C atoms forming σ bonds with sp3 hybrid orbitals. It is an aromatic hydrocarbon obtained by the symmetrical substitution of three hydrogens on the benzene ring by three methyl groups. It is widely found in coal tar and some petroleum. Appearance is a colorless liquid, toxic, flammable, and explosive. Freezing point -44.72℃, melting point -44.7℃, boiling point 164.7℃, relative density 0.8652 (20/4℃). Oxidation of paraxylene with dilute nitric acid can generate 1,3,5-benzene tricarboxylic acid. Pure homo-trimethylbenzene is produced by gas-phase catalytic dehydration of acetone at 300-500℃.

What’s the application of Mesitylene ?

• Used in the production of homophthalic acid and antioxidant, epoxy resin curing agent, polyester resin stabilizer, alkyd resin plasticizer, and dyestuff and other uses of organic synthesis raw materials, used to make homophthalic acid, and antioxidant, epoxy Chemicalbook resin curing agent, polyester resin stabilizer, alkyd resin plasticizer, the production of 2,4,6-trimethylamine for the production of reactive brilliant blue, K-3R, etc. Dyestuff. Used as analytical reagent, solvent, also used in organic synthesis, etc.
