Product Name: mixed benzene
Main ingredients: benzene, toluene, xylene and other aromatic of mixture
Physical properties: the mixed benzene at room temperature, is a colorless transparent swimming aromatic liquid, volatile, its boiling point and melting point with the composition of the mixture is different and have bigger difference, density of 0.85-0.87 is smaller than water, mixed benzene insoluble in water, 1 liters of water up the dissolved 1.8g mixed benzene; but the mixture of benzene is a good organic solvent, dissolved organic molecules and inorganic molecular polarity ability is very strong. Is a basic chemical raw materials.
Chemical properties: mixed benzene chemistry is not very lively, with chemical properties of benzene, toluene, xylene. Mixed benzene and other hydrocarbons, can burn. When oxygen is sufficient, products are carbon dioxide and water. But in the air in the combustion, bright flame and thick smoke. This is because the mass fraction of mixed benzene carbon in the larger.
Preparation: extracted from petroleum; contains a small amount of benzene, toluene and xylene in crude oil, extracted from the mixed benzene in petroleum products is the preparation method of the most widely used, but now the aromatic oil is extracted from the general are aromatic hydrocarbons separation of benzene, toluene and xylene output to meet the needs of industrial production the mixed benzene, rather than as a direct sales.
Industrial application: mainly used as solvent for industrial production of banana water, days that water, polyurethane diluent, compatible with benzene, ketone, ester and other organic solvents, used in the preparation of paint, ink, thinner and PVC adhesive, is the main raw material for the production of paint, coating. Another main purpose of mixed benzene is used as a gasoline additive.
