Application:

Methylene Chloride

1)   It has strong solubility and low toxic features. It is mainly used to produce cine film, polycarbonate, coating solvent, smoke propellant, polyurethane foams, parting agent and paint remover.

2)   It is colorless liquid. It is used for reaction intermediate in pharmaceutical industry, and used to produce ampicillin trihydrate, carbenicillin, cephalothin, etc.

Storage:

Methylene chloride

1)   Store in a cool, well - ventilated area

2)   stock temperature≤30°C relative humidity≤80% .

3)   keep away from ignition sources, heat and flame.

4)   Store in a tightly closed container.

5)   Incompatibilities; oxidants and food

 

Toxicity and protective measures:

 

1)   Methylene chloride is the least toxic of the simple chlorohydrocarbons, but it is not without health risks, as its high volatility makes it an acute inhalation hazard.

2)   It is also metabolized by the body to carbon monoxide potentially leading to carbon monoxide poisoning.

3)   Acute exposure by inhalation has resulted in optic neuropathy and hepatitis.

4)   Prolonged skin contact can result in methylene chloride dissolving some of the fatty tissues in skin, resulting in skin irritation or chemical burns.
