Sell methylbenzene

Description

Physical properties 

Toluene (Toluene) is the simplest, one of the most important aromatic compounds. In the air, toluene only incomplete combustion, flame yellow. Toluene the melting point of **5 ° C, boiling point **1 ° C. Toluene with a special aromatic flavor (and smell like benzene), at room temperature and pressure is a colorless, transparent, clear liquid such as water, density of 0.**6 g / cm 3, the refraction of light has a strong effect (refractive index: 1, ***1). Toluene is almost insoluble in water (0, *2 g / l), but it can and carbon disulfide, alcohol, ether miscible in any proportion, in chloroform, acetone and most other common organic solvents have good solubility. Viscosity of toluene to 0, 6 mPa s, that is weaker than its viscous nature of water. Toluene thermal value *0.**0 kJ / kg, flash point to 4 ° C, ignition is **5 ° C. 

Chemical properties 

Toluene is the organic compound, an aromatics, Was liquid at room temperature, colorless. Its boiling point is **0.8 ° C, freezing point **5 ° C, density of 0.**6 g / cm 3. Toluene thermometer is the use of its low freezing point than water, can be used in cold areas; And its high boiling point inferior to the boiling point of water, you can measure the temperature **0.8 ° C below. Therefore, from the temperature scale, it is better than the mercury thermometer and alcohol thermometer. Also toluene cheaper, so toluene thermometer mercury thermometers are cheaper than. 

Toluene does not dissolve in water, but soluble in ethanol and benzene solvent. Prone to chlorination of toluene to produce benzene - benzene, methyl chloride or chloroform, they are very good industrial solvents; It can extract bromine in the bromine, but can not and bromine reaction; It easy for nitrification, denitrification generate base toluene or o-nitrotoluene, which are the raw material dye; A nitration of toluene and three, get trinitrotoluene (common name TNT); It easy to sulfonation to produce acid or o-toluene sulfonamide A acid, they are doing fine in the raw material dye or sugar. 

Used as the raw materials of fuel, medicine, perfume. The solvents of nitro spray paint, paint, enamel, resin, cellulose. Cleaning agents used in the electronics industry. In the PU area is mainly used as the solvents of paints, adhesives, PU leather dry resin, and also is the raw materials of toluene diisocyanate, and aromatic diamine DMTDA, DETDA. 

Cool place sealed storage, non-corrosive to metal, available iron, mild steel, copper or aluminum containers kept.
