Core Chemistries

In addition to its core technologies of chlorination, sulfonation and methylation, CABB routinely uses other chemical reactions, being able to call on considerable experience, know-how, process technology, plants and infrastructure.

The reactions listed below in the toolbox further extend our repertoire of chemical reactions.

Bromination

CABB has the infrastructure and know-how to carry out bromination on a large industrial scale. CABB operates dedicated assets for bromination reactions, including storage facilities, pipelines and appropriate safety measures.

CUSTOMER BENEFITS:

  • Long-standing experience in bromination reactions
  • Infrastructure for large scale commercial bromination reactions
Bromination
Cross-coupling reaction

Suzuki coupling makes it possible to obtain biphenyl compounds by reacting aryl halides with arylboronic derivatives in a cross-coupling reaction. CABB has many years of experience in handling these processes safely.

CUSTOMER BENEFITS:

  • Recycling and reuse of catalysts
  • Safe and robust production processes
Suzuki coupling
Grignard reactions

The Grignard reaction is a method for linking carbon-carbon single bonds. The corresponding alcohols are produced by reacting mainly nucleophilic alkyl- or arylmagnesium halides with electrophilic compounds such as aldehydes, ketones or esters. Grignard reagents are also important in the production of boron derivatives for subsequent use in the Suzuki coupling reaction.

CUSTOMER BENEFITS:

  • Extensive experience of Grignard reactions
  • Safe and robust processes for handling hazardous reagents and intermediates
Grignard
Thioalkylation

Reacting aromatic nitro compounds with sodium alkylthiolates directly yields the corresponding aromatic thioethers. CABB is particularly well equipped to carry out these reactions. In addition to the necessary expertise, CABB also has an on-site incinerator for disposing of odorous feedstocks and products.

CUSTOMER BENEFITS:

  • Professional handling of odorous feedstocks and materials
  • Extensive experience of thioalkylation reactions
Thioalkylation
Lithiation

Carrying out lithiation reactions on a large scale entails specific and dedicated infrastructure which CABB is able to provide for its customers. CABB operates a dedicated system for lithiation reactions which includes storage tanks for lithium reagents, piping systems, appropriate safety measures and automated processes.

CUSTOMER BENEFITS:

  • Extensive experience in lithiation reactions
  • Infrastructure for large scale commercial lithiations
  • Safe and robust processes for handling hazardous reagents
Lithiation
Oxidation

In addition to chloroxidation, CABB also carries out oxidation reactions with hydrogen peroxide. Using hydrogen peroxide for oxidising aliphatic thiols and thioethers to yield sulfonyl chlorides, sulfoxides and sulfones is an alternative to chloroxidation. Oxidation reactions may also be carried out on a catalyst using air.

CUSTOMER BENEFITS:

  • Extensive experience of handling hydrogen peroxide reactions
  • Safe and robust production processes
Oxidation
Reduction/Hydrogenation

Reducing aromatic nitro compounds with hydrogen in the presence of catalysts yields the corresponding aromatic amines, while aryl halides are reduced to aromatics. CABB routinely carries out such reduction processes in the presence of palladium or platinum catalysts on its Kokkola site, making use of high grade infrastructure which ensures safe material handling.

CUSTOMER BENEFITS:

  • Safe handling of pyrophoric catalysts
  • Safe and robust production processes
Reduction
Wolff-Kishner reaction

The Wolff Kishner reaction is used for directly and selectively reducing carbonyl compounds into the corresponding alkanes. This is another example of a batch process which CABB has converted into a continuous process. The continuous process proceeds more smoothly, safely and stably, which ultimately results in higher yields and improved quality. CABB operates a dedicated plant for this reaction and furthermore has extensive experience in designing and operating continuous production processes.

CUSTOMER BENEFITS:

  • Expertise in converting batch processes into continuous processes
  • Safe and robust production processes
Wolff Kishner
Terpene chemistry

CABB's terpene chemistry is based on the conversion of α-pinene into camphene. Camphene is in turn used to obtain further downstream derivatives for various applications. Terpenes are a class of biobased, renewable feedstocks and are "biorefinery" materials. CABB is Europe's only camphene manufacturer. Thanks to our processing and technological know-how, CABB can offer a range of innovative camphene derivatives.

CUSTOMER BENEFITS:

  • Expertise in the manufacturing of camphene derivatives
  • Europe's only camphene manufacturer
Terpene chemistry
Further chemistries (toolbox)

A toolbox of further chemical reactions complements CABB's core chemistries for multistep syntheses. In addition to its core chemistries, CABB routinely carries out the listed reactions. The table gives an overview of the most usual reactions. If the product you want is not listed, please contact CABB via info@cabb-chemicals.com.
We will be happy to check whether CABB can produce it.
