  2. State of the art production: partial oxidation of n-butane over vanadyl pyrophosphate in fixed or fluidized bed. Promoting the vanadyl with Co., Ni., Fe, NB, Mo maintains catalytic activity of (VO)2P2O7 by providing strong Lewis acid sites of ((VO)xM1-x))2P2O7 • The sequence of reactions: • Dehydrogenation of butane to butene (C4H10C4H8C4H6 • Oxidation of butene: C4H6C4H4OC4H2O3 • (max n-nutaneconc in tube reactor<1.8% to avoid explosion(?), <4% in fluidized bed reactor

  3. catalysis

  4. Obsolete process by Danube Refinery in seventies : partial oxidation of benzene C6H6C4H2O3 Rather difficult to control, Rather non-selective Main problem: distillation and fumarization Renewable resource: furfural to MAA

  5. Diels Alder, Nobel prize, 1950:

  6. MSA in polymer compositions terpolymers M1: donor monomer M2,:M3,acceptor monomer CEVE: 2-chloroethy-vinylether MSA: maleic anhydride CZME: methylacyanocinnamate

  7. Surface characteristics modification: Polymer/surfactant assisted self-assembly of nanoparticles into Langmuir–Blodgett films - by polymer-surfactant compositions (poly-octadecane-co-maeic-anhydride)

  8. biodegradable polymers
