CHEMISTRY FOR TECHNOLOGISTS

 LPTC

3003

OBJECTIVES: The course aims to
• Provide conceptual understanding on spectroscopic and surface analytical techniques.
• Impart knowledge to students on the chemistry of surface and interfaces.
• make students well versed on the chemical analysis of oils, fats, soaps & lubricants.
• Provide deep knowledge to students about various classification and properties of hydrocarbon.
• familiarize students with the identification and characteristics of dyes and their applications.

UNIT I

SPECTROSCOPIC TECHNIQUES

9

Spectroscopy: Electromagnetic spectrum - absorption of radiation - electronic, vibrational and rotational transitions. Width and intensities of spectral lines. Flame photometer, Atomic absorption spectroscopy, UV- Vis, IR spectroscopy, Scanning Electron Microscope (SEM) and Transmission Electron Microscope (TEM) - principles, instrumentat on (Block diagram) and applications.

UNIT II

CHEMISTRY OF INTERFACES

9

Interface region-curved interfaces-thermodynamics of surfaces - Surface film on liquids- Adsorption of gases on Solids-adsorption isotherms – types. Applications of adsorption studies- detergency, wetting, foaming ,defoaming, spreading, water repellency.


UNIT III

OILS, FATS, SOAPS & LUBRICANTS

9

Chemical constitution, Chemical analysis of oils and fat – acid, saponification and iodine values, Definitions, determinations and signi icance. Definition, mechanism of lubrication, preparation of petrolubes, desirable characterist – vi ty, scosit ex, carbon esidue, oxidation stability, flash and fire points, cloud an pour points, aniline point. Semisolid lubricant – greases, preparation of sodium, lithi calcium le greases and uses, consistency test and drop point test.Solid lubricants – graphite and molybdenum disulphide.

UNIT IV

HYDROCARBON

9

Classification of Hydrocarbons. Aliphatic Hydrocarbons: Alkanes –l isomerism, conformations, physical, chemical reactions including free radical mechanism of halogenation, combustion and pyrolysis. Alkenes– structure of double bond, geometrical isomerism, chemical reactions: ddition of hydrogen, halogen, water, hydrogen halides, ozonolysis, oxidation. Alkynes – structure of triple bond acidic character of alkynes, addition reaction of - hydrogen, halogens, hydrogenhalides and water. Aromatic hydrocarbons - resonance, aromaticity ; mechanism of electrophilic substitution – nitration sulphonation, halogenations.

UNIT V

COLORANTS

9

Theory of colour and constitution : chromophore and auxochrome, bathochromic and hypsochromic shift, classification of dyes based on application and composition. Chemistry of azo dye – synthesis of Methyl red, Methyl orange, Congo red, phenolphthalein, fluorescein and eosin.

TOTAL : 45 PERIODS

OUTCOMES: At the end of the course, the students will be able to :
• Understand and apply spectroscopic techniques for the analysis of engineering materials for their applications.
• Make use of the applications of adsorption in detergency, wetting, spreading, foaming, de- foaming, and water repellenceand separation processes.
• Analyse and estimate oils, fats, lubricants and soap for their intended applications.
• Distinguish and demonstrate the role of different types of hydrocarbon.
• Realize the chemical structures, properties and relationships of different types of dyes and their applications.
