Mixed benzene is a compound composed of benzene and xylene. The preparation of mixed benzene can be achieved through various methods.
A common preparation method is to react a mixture solution of benzene and xylene at a specific temperature and pressure. This method can be carried out in the presence of acidic catalysts, which can be solid acids or acidic zeolites. The reaction temperature is usually in the range of 100-200 degrees Celsius, and the pressure is carried out at atmospheric pressure.
Another method for preparing mixed benzene is through the aromatization reaction of toluene. Toluene can react with hydrogen gas and catalyst in the presence of a hydrocarbon bond activator under high temperature and pressure conditions, producing a mixture of benzene and xylene.
There are other methods to prepare mixed benzene, such as direct mixing of aromatic hydrocarbons or distillation.
Mixed benzene is a mixed solvent composed of petroleum based chemical raw materials such as benzene, toluene, and xylene. Its main purpose is:
Industrial solvents: Mixed benzene is commonly used as an organic solvent in industry, especially suitable for the production and application of chemicals such as paints, coatings, adhesives, resins, etc. It has good solubility and volatility, which can quickly dissolve and diffuse other chemicals, helping to improve product quality and process efficiency.
2. Chemical reaction medium: Mixed benzene is used as a reaction medium in some chemical synthesis reactions. Chemical reactions in fields such as organic synthesis and petrochemicals typically require organic solvents to facilitate the reaction. Mixed benzene, with its good solubility and stability, can often serve as a solvent or reaction medium for reactants, providing a suitable reaction environment.
3. Energy processing: Blended benzene is also used in refining and energy processing processes. It can be used as a component of gasoline and also as a dehydrogenation agent for the production of petrochemical products such as styrene.
