with
ZEOLITE CATALYST

4.  Chemical industry has its share in polluting
the environment and today it has realized
that the time has come to make the industry
more and more efficient not only in terms of
profit and yield, but more accountable in
terms of pollution abatement and eco-
friendliness
 This has led to term GREEN CHEMISTRY
 Traditionally,organic synthesis is highly
logical, but highly inefficient . This situation
was allowed to continue mainly because

5. Fuel cells for cellular phones
Oxidation cracking process –
formation ethylene
The synthesis of ibuprofen
Safer marine antifouling
compound “sea-nine”
Technology eliminating CFC

7.  Zeolites are crystalline aluminosilicates with
exchangeable cations
 The cations can be exchanged with protons that
make them acidic solids
 Si:Al ratio can vary in zeolites from 1 to infinity
 No.of acidic sites decreases with increase in the
Si:Al ratio
 Strength of the acidic sites increases with the Si:Al
ratio
 There are also Lewis acid sites(tri-coordinated Al)
 They have micro-pores of entry port size varying
from about 3 to 12A

8.  Zeolites are formed by oxygen-sharing T(Si or Al)
atoms, each T atom linked to four oxygen
making tetrahedra
 These tetrahedra are linked to form rings
containing equal no. of oxygen and silicon
atoms
 The rings share common oxygen(or silicon)
forming different polyhedra
 The polyhedra then join by sharing common
oxygen(or silicon) forming the three dimensional
net work structure giving rise to pores
 The pores may be all in one direction or many
run in several directions

16.  Reductionof atmospheric oxides of
nitrogen(NOx)
 Cutting emission of VOCs
 Process improvements in CPI.
