UV light for photochemical processes

Many organic syntheses are substantially accelerated or made possible in the first place by exposure to UV radiation.

Photochemical processes UV

In contrast to thermal excitation, light-induced reactions often take place already at room temperature and hence much more gently.
Moreover, less by-products are generated.

Photochemical processes can also be used with a specific purpose, e.g. to decompose pollutants or remove toxic substances.

In addition to the conventional, long-proven reaction process in stirred tank reactors, chemical reactions are increasingly performed in microreactors, which enables even easier and more efficient implementation of photochemical reaction steps.

Your advantages with UV light:

  • Selective implementation
  • Less by-products
  • Method gentle to materials
  • Can be used on macroscopic and microscopic scale
  • Pollutant degradation without addition of aggressive chemicals

Fields of application of photochemical processes:

  • Synthesis: Isomerisation, polymerisation, addition etc.
  • Analysis: TOC detection, detection of heavy metals
  • Sewage treatment:Decomposition of chlorinated hydrocarbons (CHC) and adsorbable organic halogen compounds (AOX)
  • Production of ultra-pure water:Decomposition of organic contaminates
  • Drinking water treatment:For sterilisation, decomposition of pesticides
  • Pharmaceutical and cosmetics research: Examination of photostability
  • Beverage and food industry:Removal of microorganisms, disinfection
