Bromination Bromination can be performed either with elemental bromine (Br2) or with bromide salts and an oxidant, such as hydrogen peroxide. Target molecules: Brominated hydrocarbons Advantage CABB: Kokkola has the infrastructure and expertise to carry out bromination on a large industrial scale with dedicated storage and transfer lines for safety and optimal efficiency. Chlorination Chlorination can be performed via the following routes to address yield, purity and cost: Direct Chlorination with chlorine Target molecules: Chlorinated hydrocarbons Advantage CABB: Pratteln operates a state-of-the-art chlor-alkali electrolysis and a highly integrated production site capable of recycling by-products into value streams. Reactions are performed in both continuous and batch processes, from small scale to large commercial quantities. Chlorination with thionyl chloride Target molecules: Alkyl or aryl chlorides Acid chlorides or sulfonyl chlorides Advantage CABB: Pratteln’s continuous chlorination processes increase yields, purity and reduce unwanted by-products. Chlorination with sulfuryl chloride Target molecules: Carbonyl compounds Benzyl positions Aromatics Advantage CABB: Pratteln uses sulfuryl chloride as an alternative chlorinating reagent for greater selectivity when processing carbonyl compounds, benzylic positions and aromatics. Chloromethylation Target molecules: Chloromethyl ethers and esters Advantage CABB: Our patented chloromethylation process converts alcohols and carboxylic acids to chloromethyl ethers and esters with a low by-product spectrum, high yield and a low bis-chloromethyl ether content.
