Chlorination

Chlorination is a central chemical reaction for the products manufactured by CABB. This applies both to our single most important product, monochloroacetic acid (MCA) and to chlorination reagents and derivatives used as fine chemicals or in custom synthesis.CABB is reintegrated into our own chlorine production with state-of-the-art and energy-efficient membrane electrolysis. While the Gersthofen, Jining and Knapsack sites use chlorine almost exclusively for the production of monochloroacetic acid, the Pratteln and Kokkola sites manufacture various chlorination reagents for the production of a wide variety of fine chemicals.

For reasons of environmental protection and safety, we transport chlorination reagents in closed piping systems. Gaseous by-products from the chlorination process are recycled and returned to the integrated production system.

Your benefits:

  • Reintegration into reagents and chlorinated intermediates
  • Sustainable production processes
  • Efficient chlorination processes in batch and continuous processes
  • Environmentally friendly recycling of secondary flows
Liquid and gaseous chlorine is used for the direct chlorination of hydrocarbons to carbonyl, benzyl and aromatic chlorine compounds. CABB has its own electrolysis facilities for the production of chlorine.

We perform chlorination reactions in both continuous and batch processes, from small scale to large commercial quantities. Our leading individual product, monochloroacetic acid, is manufactured using this chlorination technology.

Your benefits:

  • Reintegration into reagents
  • Sustainable production processes
  • Efficient chlorination processes in batch and continuous processes
  • Environmentally friendly recycling of secondary flows

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

Sulfuryl chloride is an alternative chlorinating reagent to chlorine. It has a more selective effect in the chlorination of carbonyl compounds, benzyl positions and aromatics. In chlorination reactions with sulfuryl chloride, HCl and SO2 are formed as exhaust gases.

We offer you the possibility of customer-specific chlorination in our integrated production 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.

Chloromethylation of alcohols and carboxylic acids results in the corresponding chloromethyl ethers and chloromethyl esters. CABB’s patented process guarantees a gentle process with a low by-product spectrum, high yield and a very low content of bis-chloromethyl ether. At the same time, our customers benefit from the CABB integrated production system, which makes the chlorination reagents from the pipeline available and recycles the resulting by-products.

We offer a wide range of chloromethyl ethers and esters.

Your benefits:

  • Reintegration in reagents
  • Sustainable production processes
  • Environmentally friendly recycling of secondary flows
  • Wide range of chloromethyl ethers and esters
  • Lowest possible content of bischloromethyl ether

Oxidation of aliphatic thiols or thioethers with chlorine leads to the corresponding sulfonyl chlorides and sulfones and provides direct and advantageous access to these product groups. With CABB, you also benefit from our integrated production system, in which chlorine is available directly via the pipeline and gaseous by-products are sustainably reused for further production.

In addition, we also carry out oxidations with oxygen and hydrogen peroxide.

Your benefits:

  • Reintegration in reagents
  • Sustainable production processes
  • Environmentally friendly recycling of secondary flows
