Chlorination

CABB operates various chlorination processes at its production sites. Due to our highly integrated production facilities, various chlorination reagents (chlorine, hydrochloric acid, thionyl chloride, and sulfuryl chloride, respectively) are available on site. In many cases we are able to carry out the reactions in both continuous and batch processes.

In keeping with our strong commitment to safe and ecologically sustainable production, we supply corrosive and hazardous reagents via pipeline to our production facilities. In many reaction processes considerable amounts of corrosive process gases (HCl and SO2) are formed. They are recycled and fed back into the integrated production system.


Chlorination with thionyl chloride

The chlorination of alcohols, carboxylic acids or sulfonic acids with thionyl chloride leads to alkyl and aryl chlorides, acid chlorides, and sulfonyl chlorides, respectively.

For specific products please check the following product groups:

Carboxylic acid chlorides
Chloroalkyl ethers
Chloroethyl amines
Sulfonyl chlorides, aliphatic
Sulfonyl chlorides, aromatic


Chlorination with chlorine

Carbonyl, benzylic and aromatic compounds can be mono- and perchlorinated with chlorine. We carry out these reactions by applying liquid and gaseous chlorine in loop and batch reactors.

For specific products please check the following product groups:  

Carboxylic acids and salts
Carboxylic acid esters
Alkyl and aryl chlorides


Chlorination with sulfuryl chloride

Sulfuryl chloride is used as an alternative to chlorine. As a reagent it is more selective in the chlorination of carbonyl compounds, benzylic positions and aromatics.


For specific products please check the following product groups:

Alkyl and aryl chlorides
Carboxylic acid esters
Sulfonyl chlorides, aromatic
Sulfonyl chlorides, aliphatic
