Lonza Group expanded its ozonolysis capacity
Lonza Group’s Business Sector Exclusive Synthesis has recently expanded its Ozonolysis capacity by installing a new ozone generator with a 8 kg/h capacity, a continuous ozonolysis reactor and a multipurpose train for downstream processing at its Launch Plant in Visp, Switzerland. This set-up allows the manufacture of several hundred tonnes of intermediates per year.
The fully automated facility has successfully come on stream in the first half of 2001 and is designed for ozonolysis at low temperatures in particular. The short residence times allow higher selectivity and the handling of unstable intermediates.
Lonza has been performing ozonolysis for high value added intermediates since 1987 using semi-batch processes.
Ozone is a versatile oxidizing agent that is mostly used to introduce oxygen in unsaturated and saturated hydrocarbons. In general the molecule itself generates no other side products apart from oxygen allowing the application of economical and environmentally friendly processes.
