Sulfonation






           
  • A  Industrial chemical process used to make a diverse range of products such as dyes and color intensifiers, pigments, medicinal, pesticides and organic intermediates is called Sulfonation.
  • Reactions are carried out using, concentrated sulfuric acid, Oleum or sulfur tri oxide as the sulfonating agent.
  • A difficult reaction to perform on an industrial scale because the reaction is rapid and highly exothermic.
  • Commercial scale Sulfonation reactions require special equipment and instrumentation that allows tight control of the mole ratio of SO3 to organic and rapid removal of the heat of reaction. 
  • The process equipment cost is an important factor to be considered in choice of a Sulfonation process.
