Tulsion Resin Catalyst-Image

Specially manufactured, Tulsion® cation exchange resins in Hydrogen form as well as anion exchange resins in hydroxyl form can be used as catalysts. The former are used as catalyst for reactions that are normally catalysed by mineral acids, the latter are used for base catalyzed reactions. Catalysis by cation exchange resin is by far more common. 

The advantages of using Tulsion® resin as catalysts as compared to homogeneous acid catalysts are as follows:

Ease of separation from reacting mixtures, hence suitable for continuous reactions

Not necessary to neutralize or concentrate the catalyst

Reusability of catalyst

Elimination of waste disposal problems

Low equipment costs as it can be used in mild steel reactors

Higher selectivity to the desired product and fewer by products

Higher rate of reaction and higher yields etc. 

Examples of Tulsion resin catalysed reactions are:

  • Alkylation of phenols
  • Esterification
  • Acetalization or Ketalization
  • Aldol condensation
  • Alkylation of aromatic hydrocarbons
  • Condensation
  • Etherification
  • Hydration of olefins
  • Knovenagel condensation
  • Hydrolysis
  • Polymerization and isomerization
  • Tansesterification
