CAS No.75-09-2 Methylene Chloride 99.9%

The CAS number 75-09-2 corresponds to the chemical compound ethyl alcohol, also known as ethanol or grain alcohol. It is a clear, colorless liquid and is commonly used as a solvent and as a fuel. Ethanol is also the principal type of alcohol found in alcoholic beverages.

The use of dichloromethane is safer than chloroform, so it is often used instead of chloroform as the extractant heavier than water. Ordinary dichloromethane can generally be used as an extractant directly. If Chemicalbook purification is required, it can be washed with 5% sodium carbonate solution, then washed with water, dried with anhydrous calcium chloride, distilled and collected at 40~41 ℃, and stored in a brown bottle.

The CAS number 75-09-2 belongs to the chemical compound ethylene oxide. It is a colorless gas with a slightly sweet odor and is commonly used as a pesticide and a sterilizing agent for medical equipment. It is also used in the production of various other chemicals, including glycol ethers, ethanolamines, and polyethylene terephthalate (PET). Ethylene oxide is highly flammable and can be hazardous if not handled properly. Inhalation of the gas can cause respiratory irritation, while prolonged exposure can lead to neurological effects and even cancer.

Methylene Chloride (CAS No. 75-09-2) is a versatile industrial solvent that finds numerous applications in various industries worldwide. Some of the major applications of Methylene Chloride are as follows:

1. Paint Stripping: Methylene Chloride is widely used as a paint stripper due to its excellent solvency power. It can easily dissolve and remove all kinds of paint and varnishes from metal parts, automotive components, and furniture.

2. Solvent Extraction: Methylene Chloride is used for solvent extraction of pharmaceuticals, essential oils, and other botanicals. It is also used for the extraction of caffeine from coffee beans and tea leaves.

3. Aerosol Spray Propellant: Methylene Chloride is used as a propellant in aerosol cans due to its low boiling point and high vapor pressure. It is commonly used in personal care products such as deodorants, hairsprays, and air fresheners.

4. Chemical Synthesis: Methylene Chloride is widely used as a solvent in various chemical reactions such as in the production of pharmaceutical, agrochemical, and specialty chemicals.

5. Refrigerant: Methylene Chloride is used as a working fluid in some refrigeration systems due to its low boiling point and high heat capacity.

6. Metal Cleaning: Methylene Chloride is used for cleaning metal parts and components in the automotive and aerospace industries.

7. Adhesive Production: Methylene Chloride is used in the production of adhesives and sealants due to its excellent solvency power and fast evaporation rate.

8. Foam Blowing Agent: Methylene Chloride is used as a blowing agent in the production of polyurethane foam insulation.

Overall, Methylene Chloride is a versatile compound with a wide range of applications in different industries. However, it is important to handle it with care as it can be hazardous if not used properly.
