Falling -Film Photoreactors

Bleaching

Falling -Film Photoreactors

Brominated intermediates for synthesis (e.g. substituted benzylbromides)

Side-Loop Photoreactors

Chlorinated intermediates for synthesis (e.g. benzylchloride, benzalchloride, methylchloride)

Side-Loop Photoreactors

Chlorinated solvents (e.g. dichloromethane, chloroform, tetrachloromethane)

Side-Loop Photoreactors

Fluorinations, Sulfoxidations, Nitrosylations

Side-Loop Photoreactors

Fragerances (e.g. Rose Oxyde via Singlet Oxygen Reaction)

Plug-Flow Photoreactors

Fragrances (e.g. singlet oxygen reaction: Rose oxide)

Side-Loop Photoreactors

Intermediates for diagnostics (e.g. by photo- bromination or photo-iodination)

Side-Loop Photoreactors

Lubricants (e.g. Fomblin)

Side-Loop Photoreactors

Material modifications (processes in heterogeneous – liquid/liquid and solid/liquid – media (e.g. chlorinated rubbers, chlorinated PVC (C-PVC))

Photohalogenations

Agitated Photoreactors

Photooxidations implying radical intermediates (e.g. AOP)

Falling -Film Photoreactors

Photopolymerizations (radical and cationic) in heterogeneous – liquid/liquid and solid/liquid – media) (e.g. Caprolactam as pre-cursor of Nylon 6, Lauryllactam as pre-cursor of Nylon 12, Polyacrylates, Polystyrenes and co-polymers, mini-emulsions with monomer functionalization)

Agitated Photoreactors

Plant treatment intermediates (e.g. pinacols by photo-hydrodimerisation)

Side-Loop Photoreactors

Polymer and co-polymer specialities (photopolymerization in homogeneous (liquid), heterogeneous (liquid/liquid and liquid/gas (aerosols) media)

Side-Loop Photoreactors

Preparative photochemistry in general implying strongly absorbing substrates and/or radical imtermediates
