CY2111 ENGINEERING CHEMISTRY – I
UNIT I WATER TECHNOLOGY
Characteristics – alkalinity – types of alkalinity and determination – hardness – types and estimation by EDTA method (problems); Domestic water treatment – disinfection
methods (Chlorination, ozonation. UV treatment) – Boiler feed water – requirements –
disadvantages of using hard water in boilers – internal conditioning (phosphate, calgon and carbonate conditioning methods) – external conditioning – demineralization process – desalination and reverse osmosis.
UNIT II POLYMERS AND COMPOSITES
Polymers-definition – polymerization – types – addition and condensation polymerization– free radical polymerization mechanism – Plastics, classification – preparation, properties and uses of PVC, Teflon, polycarbonate, polyurethane, nylon-6,6, PETRubber -vulcanization of rubber, synthetic rubbers – buty1 rubber, SBR, Composites – definition, types polymer matrix composites – FRP only.
UNIT III SURFACE CHEMISTRY
Adsorption – types – adsorption of gases on solids – adsorption isotherms – Frendlich
and Langmuir isotherms – adsorption of solutes from solution – role of adsorbents in
catalysis, ion-exchange adsorption and pollution abatement.
UNIT IV NON-CONVENTIONAL ENERGY SOURCES AND
Nuclear energy – fission and fusion reactions and light water nuclear reactor for power
generation (block diagram only) – breeder reactor – solar energy conversion – solar cells – wind energy – fuel cells – hydrogen – oxygen fuel cell – batteries – alkaline batteries – lead–acid, nickel–cadmium and lithium batteries.
UNIT V ENGINEERING MATERIALS
Refractories – classification – acidic, basic and neutral refractories – properties
(refractoriness, refractoriness under load, dimensional stability, porosity, thermal
spalling) – manufacture of alumina, magnesite and zirconia bricks, Abrasives – natural
