Main ingredients: benzene, toluene, xylene and other aromatic compounds
Physical properties : The liquid , volatile , boiling point and melting point of the mixed benzene at normal temperature are colorless , transparent and aromatic odor . The boiling point and melting point of the mixed benzene are different depending on the composition of the mixture , the density is 0.85 - 0.87 , the water is small , the mixed benzene is difficult to dissolve in water , and 1.8 g of mixed benzene is dissolved in 1 liter of water .However , mixed benzene is a good organic solvent , the ability to dissolve organic molecules and some non - polar inorganic molecules is very strong . It is a basic chemical raw material .
Chemical properties: the chemical properties of mixed benzene is not very active, with general pure benzene, toluene, xylene chemical properties. Mixed benzene, like other hydrocarbons, can burn. When oxygen is sufficient, the product is carbon dioxide and water. But when burning in the air, the flame is bright and has thick black smoke. This is due to the higher mass fraction of carbon in mixed benzene. Nanjing Zhuocai Chemical Co., Ltd. mixed benzene distillation range is 80-1 201-145 two kinds.
Production preparation: extraction from petroleum; containing small amounts of benzene, toluene and xylene in crude oil; extraction of mixed benzene from petroleum products is the most widely used method of preparation, However, the aromatics extracted from petroleum are generally separated from aromatics to produce pure benzene, toluene and xylene to meet the needs of industrial production, but less direct sale as mixed benzene. Industrial use: mainly used as solvent to make banana water, Tianna water, polyurethane diluent, and other organic solvents, such as benzene, ketone, ester, etc., used in the preparation of paint, ink, diluent and PVC adhesive, is the production of paint, The main raw material of paint. Another major use of mixed benzene is as a gasoline additive
