The molecular structure of mesitylene (also known as mesitylene, molecular formula is C9H12) is σ bond which formed by benzene ring C atoms by means of sp2 hybrid orbital, other C atoms form σ bond by means of sp3 hybrid orbital, it is functional group in the presence of many multi organic compounds. It is aromatic hydrocarbon which obtained by three hydrogens symmetrically-substituted by three methyl in benzene ring.It is widespread in coal tar and certain petroleum. It is colorless liquid, toxic, flammable and explosive. The freezing point is-44.72 ℃, melting point is-44.7 ℃, boiling point is 164.7 ℃, the relative density is 0.8652 (20/4℃). Mesitylene can generate trimesic acid with the oxidation of dilute nitric acid. Pure mesitylene is made by acetone in vapor phase catalytic dehydrationthe at 300~500℃.
Mesitylene is important organic chemical raw material, the use of mesitylene can develop three toluene, trimesic acid, benzoic anhydride and other dye intermediates, it can also be used for the production of antioxidants, polyester resin curing agent, stabilizer, alkyd resins and plasticizers. Since mesitylene is a good solvent, and it is flammable, irritant, and it has low freezing point. In the electronics industry, it is used as developer of photosensitive sheet silicone.
Mesitylene is also common volatile organic compound (VOC) in city, this is mainly generated by the combustion. It plays an important role (including aerosol and tropospheric ozone generation) in many chemical reactions in the atmosphere. Since the three hydrogens on the aromatic ring have the same chemical environment, in the mesitylene magnetic resonance spectrum hydrogen spectrum only has a single peak which peak area is corresponding to three hydrogen in the vicinity of 6.8ppm. Therefore, mesitylene is sometimes used as internal standard substance in proton nuclear magnetic resonance method which comprises aromatic organic samples.
The annual demand of mesitylene is about 100,000 tons in current domestic market.
The above information is edited by the chemicalbook of Wang Xiaodong.

Purification Methods

Dry it with CaCl2 and distil it from Na in a glass helices-packed column. Treat it with silica gel and redistil it. Alternative purifications include vapour-phase chromatography, or fractional distillation followed by azeotropic distillation with 2-methoxyethanol (which is subsequently washed out with H2O), drying and fractional distilling. More exhaustive purification uses sulfonation by dissolving in two volumes of conc H2SO4, precipitating with four volumes of conc HCl at 0o, washing with conc HCl and recrystallising from CHCl3. The mesitylene sulfonic acid is hydrolysed with boiling 20% HCl and steam distilled. The separated mesitylene is dried (MgSO4 or CaSO4) and distilled. It can also be fractionally crystallised from the melt at low temperatures. [Beilstein 5 IV 1016.]

Chemical Properties

It is colorless transparent liquid. It is insoluble in water, soluble in ethanol, it can dissolve in benzene, ether, acetone in any proportion.

Production method

1. It is derived by the separation of C9 aromatic hydrocarbon. 2. In the reforming of heavy aromatics the amount of mesitylene is about 11.8%. However, due to its boiling point (164.7 ℃) is extremely close to the boiling point of O-methyl benzene (165.15 ℃), it is difficult to separate for using distillation method. 3.The isomerization method with partial three toluene as raw material can fractionate, and can get mesitylene which the one way yield is 21.6%, the purity is more than 95%, while 4%-7% of by-product is durene, xylene is 9%. The average temperature of reactor bed is 260℃, pressure is 2.35MPa, empty the entire is 1.0h-1, molar ratio of reforming hydrogen and oil is 10: 1, the catalyst is mordenite which lack of aluminum hydrogen form: Cu: Ni: binder = 85.2: 0.5: 15. Under these conditions, the conversion rate of partial three toluene is 46%, selectivity is 47% , one way yield of mesitylene is 21.6%. HF-BF3 is xylene separated and through the method of isomerization by Japanese Mitsubishi Gas Company, by-products contain high concentration of mesitylene of high boiling, the goods can be get by distilled and refined. 4. Acetone in sulfuric acid-catalyzed goes through dehydration synthesis can obtain this goods with the yield of 13%-15%. 4600g (79mol) of industrial acetone is cooled to 0-5℃, and 4160ml concentrated sulfuric acid is added with stirring, the temperature can not exceed 10℃. After addition is completed, cntinue stirring 3-4h, place at room temperature for 18-24h. The product is subjected to steam distillation, mesitylene is separated, then it is washed with alkali, water, and then collect distillation fraction of 210℃, 15g sodium metal is added into this fraction, it is heated to near the boiling point, 2/3 liquid is evaporated. the residue is distilled to 210℃, efficient fractionation collection is done for the 163-167℃ distillate, 430-470g1,3,5-mesitylene can be obtained.

Storage characteristics

Treasury should have ventilation and be low-temperature drying; and it should stored separately with oxidants.
