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

STORAGE DEVICES

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

and synthetic abrasives – quartz, corundum, emery, garnet, diamond, silicon carbide

and boron carbide. Lubricants – mechanism of lubrication, liquid lubricants, – properties – viscosity index, flash and fire points, cloud and pour points, oilyness) – solid lubricants– graphite and molybdenum sulphide. Nanomaterials – introduction to nanochemistry –carbon nanotubes and their applications
