Chlorination of molecules with functional groups such as alcohols, carboxylic acids or sulfonic acids is carried out with thionyl chloride. This produces the corresponding alkyl or aryl chlorides, acid chlorides or sulfonyl chlorides.
Chlorination reactions with thionyl chloride produce HCl and SO2 as exhaust gases. CABB offers the possibility of customer-specific chlorination within the integrated system, in which the exhaust gases are separated, purified and reused as raw materials. This enables sustainable production, from pilot plants to large-volume commercial quantities in both batch and continuous processes.
One of our strengths is to design chlorinations as continuous processes from the outset or to convert batch processes into continuous processes. This increases yield and purity and reduces the proportion of unwanted by-products.
- Reintegration into reagents
- Sustainable production processes
- Efficient chlorination processes in batch and continuous processes
- Environmentally friendly recycling of secondary flows
