What is methylene chloride 75 09 2?
Methylene Chloride, also known as dichloromethane, is an organic compound.It is a colorless, volatile liquid with a slightly sweet odor and is widely used as a solvent in various industrial and chemical processes.
The table below summarizes some key properties and applications of methylene chloride 75 09 2:
| Property | Value |
|---|---|
| Chemical Formula | CH₂Cl₂ |
| Boiling Point | 39.6°C (103.3°F) |
| Density | 1.326 g/cm³ |
| Solubility | Miscible in many solvents |
| Common Uses | Paint stripping, solvent extraction, chemical processing, pharmaceuticals |
Some of the main applications of methylene chloride 75 09 2 are:
- As a solvent for the synthesis of pharmaceuticals, pesticides, polymers, adhesives, etc.
- As an extraction agent for caffeine, spices, hops, essential oils, etc.
- As a paint remover for furniture, aircraft, automobiles, etc.
- As a degreaser for metal parts, electronic components, etc.
- As a propellant for aerosols, such as paints, insecticides, etc.
- As a process solvent for the production of cellulose acetate films, polycarbonate plastics, etc.
How is methylene chloride 75 09 2 produced?
Dichloromethane is primarily produced by the chlorination of methane. Methane reacts with chlorine gas under heat or UV light, forming methyl chloride, which is further chlorinated to produce dichloromethane. The resulting mixture is then separated by distillation to isolate dichloromethane.
How Much DCM (75 09 2) Is Toxic?
The toxicity of methylene chloride depends on the type of exposure. Both inhalation and ingestion can cause irritation to mucous membranes, as well as nausea and vomiting, even in small amounts. At higher amounts, it can be fatal.
According to the EPA, there have been 85 fatalities caused by dichloromethane since 1980, mostly due to inhalation in poorly ventilated environments.
In Europe, the Scientific Committee on Occupational Exposure Limit Values (SCOEL) recommends a time-weighted average of 100 parts per million (ppm) over 8 hours, as well as a short-term exposure limit (STEL) of 200 per 15 minutes.
In the U.S., the Occupational Safety and Health Administration (OSHA.gov) and the National Institute for Occupational Safety and Health (CDC.gov/NIOSH) have set exposure limits of 25 ppm over 8 hours or 125 ppm over 15 minutes.
What Are Some Alternatives to methylene chloride 75 09 2?
Some alternatives to methylene chloride (CAS 75-09-2) include less harmful solvents such as acetone, ethanol, ethyl acetate, and methyl ethyl ketone.
