Chemical Properties:
Methylene chloride reacts strongly with active metals
such as potassium, sodium, and lithium, and strong bases, for instance, potassium
tert-butoxide. However, the compound is incompatible with strong caustics,
strong oxidizers, and metals that are chemically active such as magnesium and
aluminum powders.
It is noteworthy that methylene chloride can attack some forms of coatings,
plastic, and rubber. In addition, dichloromethane reacts with liquid oxygen,
sodium-potassium alloy, and nitrogen tetroxide. When the compound comes into
contact with water, it corrodes some stainless steels, nickel, copper as well
as iron.
When exposed to heat or water, dichloromethane becomes very sensitive as it is
subjected to hydrolysis that is hastened by light. Under normal conditions,
solutions of DCM such as acetone or ethanol should be stable for 24 hours.
Methylene chloride does not react with alkali metals, zinc, amines, magnesium,
as well as alloys of zinc and aluminum. When mixed with nitric acid or
dinitrogen pentoxide, the compound can vigorously explode. Methylene chloride
is flammable when mixed with methanol vapor in the air.
Since the compound can explode, it is important to avoid certain conditions
such as sparks, hot surfaces, open flames, heat, static discharge, and other
ignition sources.
Application:
House Hold
Uses
The compound is used in bathtub refurbishing. Dichloromethane is highly used
industrially in the production of pharmaceuticals, strippers, and process
solvents.
Industrial and Manufacturing Uses
DCM is a solvent that is found in varnish and paint strippers, which are often
used to remove varnish or paint coatings from various surfaces. As a solvent in
the pharmaceutical industry, DCM is used for the preparation of cephalosporin
and ampicillin.
Food and Beverage Manufacturing
It is also used in manufacturing beverage and food manufacturing as an
extraction solvent. For instance, DCM can be used to decaffeinate unroasted
coffee beans as well as tea leaves. The compound is also used in creating hops
extract for beer, beverages and other flavoring for foods, as well as in
processing spices.
Transportation Industry
DCM is
normally used in the degreasing of metal parts and surfaces, such as railroad
equipment and tracks as well as airplane components. It can also be used in
degreasing and lubricating products utilized in automotive products, for
instance, removal of the gasket and for preparing metal parts for a new
gasket.
Experts in automotive commonly use vapor dichloromethane degreasing process to
for the removal of grease and oils from car parts of car transistor, spacecraft
assemblies, aircraft components, and diesel motors. Today, specialists are able
to safely and quickly clean transportation systems using degreasing techniques
that depend on methylene chloride.
Medical Industry
Dichloromethane is used in laboratories in the extraction of chemicals from
foods or plants for medicines such as antibiotics, steroids, and vitamins. In
addition, medical equipment can be efficiently and quickly cleaned using
dichloromethane cleaners while avoiding damage to heat-sensitive parts and
corrosion problems.
Photographic Films
Methylene chloride is used as a solvent in the production of cellulose
triacetate (CTA), which is applied in the creation of safety films in
photography. When dissolved in DCM, CTA begins to evaporate as the fibre of
acetate remains behind.
Electronic Industry
Methylene chloride is used in the production of printed circuit boards in the
electronic industry. DCM is utilized to degrease the foil surface of the
substrate before the photoresist layer is added to the board.
