 INTRODUCTION
:
 What Is Formaldehyde?
• Formaldehyde (CH2O) is an important
compound for the global economy, widely used
in construction, wood processing, furniture,
textiles and carpeting, and the chemical
industry.
• Formaldehyde is naturally present in the
environment, some food, and the human body .
• Formaldehyde was first reported in 1859 by the
Russian chemist Aleksandr Butlerov (1828–86).
• Molecular formaldehyde. A colorless gas with a
characteristic pungent, irritating odor. It is stable
at about 150 °C, but polymerizes when
condensed to a liquid.

Sheet):
• First Aid Measures:
Inhalation:
• Remove victim to fresh air
and keep at rest in a
position comfortable for
breathing.
SKIN (or Hair):
• Take off immediately all
contaminated clothing. •
Rinse skin with
water/shower.
Eyes:
• Rinse cautiously with
water for several minutes. •
Remove contact lenses, if
present.
• Handling:
• Take precautionary
measures against
electrostatic discharges.
• Ground the container while
dispensing.
• Do not use pressure to
dispense.
• Keep away from open
flames, hot surfaces and
sources of ignition.
• Use only non-sparking
tools.

15.  Applications:
1. Disinfectant and biocide:
• An aqueous solution of formaldehyde can be useful
as a disinfectant as it kills most bacteria and fungi
(including their spores).
• Formaldehyde is also approved for use in the
manufacture of animal feeds in the US. It is an
antimicrobial agent used to maintain complete animal
feeds or feed ingredients.
2. Drug testing:
• Formaldehyde and an 18 M (concentrated) sulfuric
acid makes Marquis reagent—which can identify
alkaloids and other compounds
15

16.  Applications:
3. Industrial applications:
• Formaldehyde is a common precursor to more complex
compounds and materials.
• Products generated from formaldehyde are urea
formaldehyde resin, melamine resin, phenol formaldehyde
resin, polyoxymethylene plastics, 1,4-butanediol, and
methylene diphenyl diisocyanate.
• The textile industry uses formaldehyde-based resins as
finishers to make fabrics crease-resistant.
• Formaldehyde-based materials are key to the
manufacture of automobiles, and used to make
components for the transmission, electrical system, engine
block, door panels, axles and brake shoes.

17.  Applications:
4.Health Care Applications:
• Formaldehyde has a long history of safe use in the
manufacture of vaccines, anti-infective drugs and hard-gel
capsules.
• For example, formaldehyde is used to inactivate viruses
so they don’t cause disease, such as the influenza virus in
making the influenza vaccine.
5. Automobiles:
• Formaldehyde technology helps to make vehicles lighter
and more energy efficient. Formaldehyde-based resins are
used to make interior molded components that need to
withstand high temperatures.
• These resins are also used in the production of highly
durable exterior primers, clear coat paints and fuel system
components. 17

19.  Some Facts about
Formaldehyde:
• Exposure of formaldehyde to animals like rat
have shown to cause cancer in laboratory.
• Studies have found that use formaldehyde
have increased the risk of leukaemia.
• Another studies have found that workers
exposed to formaldehyde have higher than
normal levels of chromosomes changes in early
WBC in the bone marrow.
• Some expert agencies like NTP, IARC, EPA,
NCI have concluded that "formaldehyde can be
carcinogen to humans".
