Anhydrous benzene - Names and Identifiers
Anhydrous benzene - Introduction
Anhydrous benzene is a benzene solution with water removed, and its chemical formula is C6H6. The following is a description of the nature, use, preparation and safety information of Anhydrous benzene:
Nature:
1. Anhydrous benzene is a colorless, organic solvent, with a unique aromatic odor.
2. It has a lower boiling point (80.1 ℃) and a higher flash point (-11 ℃), volatile and flammable.
3. Anhydrous benzene is a low polarity solvent, soluble in non-polar organic solvents, such as ethyl ether, ethyl acetate, etc.
Use:
1. Anhydrous benzene is mainly used as a solvent for organic synthesis reactions, and has a wide range of applications in pharmaceutical synthesis, dye synthesis, coatings and adhesive manufacturing.
2. It is also commonly used to extract and separate natural and synthetic compounds, such as aromatic hydrocarbons from crude oil.
3. Anhydrous benzene can also be used as solvents and coolants for the manufacture of electronic devices and electronic cooling systems.
Preparation Method:
1. Anhydrous benzene is usually obtained by removing water from conventional benzene solutions. The common method is to contact benzene with desiccant (such as molecular sieve, anhydrous sodium chloride, etc.) to adsorb and remove water.
2. Anhydrous benzene with high purity can also be obtained by distillation and drying.
Safety Information:
1. the Anhydrous benzene is flammable, so pay attention to fire prevention and avoid open fire, high temperature and other fire sources.
2. use should be equipped with appropriate protective measures, such as wearing protective glasses, gloves and work clothes.
3. avoid inhalation of Anhydrous benzene vapor or contact with the skin, so as not to cause irritation, allergic or toxic reaction.
4. In case of accidental inhalation or skin contact, immediately move to a well-ventilated place and seek medical assistance.
5. Keep the container sealed during storage, away from fire, heat and oxidant.
