Course objectives:
|
Basic characterization, properties, manufacturing process, raw materials and aplication basics of surface active substancies. (tensides, surfactants).
|
Requirements on student
|
Oral exam. The debate over selected lines is basic part of exam. Student exhibit the rate of acquired knowledge.
|
Content
|
Basic surfactant - surface active agents - (tenside) concepts - surfactant mechanisms, surfactant microstructures, hydrophile and lipophile portion of the molecule of surfactant, micelles - critical micelle concentration, solubillisation, surfactant phase diagrams, surfactant properties at interfaces - Gibbs free energy, Gibbs sorption isotherm. Hydrophile - lipophile balance, or HLB number. Anionic surfactants. Long - chain fatty acid - sodium or potassium salts as soap. Fatty alcohol sulfates (alkyl sulfates) Alcohol ether sulfates (AES) or alkyl ether sulfates or alcohol etoxysulfates. Sulfonate - LAS (linear alkylbenzensulfonate, ? - olefinfulfonate, methylestersulfonate, alkylsulfonate. Nonionic surfactants. Alkyl-poly oxyelhylene ethers (oxyethylenated fatty alcohols), , alkylphenols exyethylenate, ethylene oxide/propylene oxide (EO/PO) block copolymers. Alkyl polyglykoside as surfactants from plants. Cationic (quaternary ammonium salts) and amphoteric surfactants. Basic surfactants performance - wetting, soil removal, stabilize foam, bactericide, emulsion and microemulsion. Electro double - layer Surfactants - production of hair and body shampoo, hard - surface cleaners, machine dishwash detergents. Laundry products (detergents) - composition.
