Industrial Uses

1. Performance Chemicals

  • Phase Transfer Catalyst: TMAB facilitates reactions between compounds that are not soluble in the same solvent. It does this by transferring one reactant from one phase (e.g., water) to another (e.g., an organic solvent) where the reaction can occur, thereby increasing reaction rates and yields.

2. Fabric Solutions

  • Textile Softener: It is also used as a softening agent in the textile and paper industries.

3. Pharmaceuticals

  • Phase Transfer Catalyst: TMABr acts as a phase transfer catalyst, enabling reactions between substances that normally don't mix well, like oil and water. This is crucial in pharmaceutical synthesis where many reactions involve different solubility properties. 
  • Reagent in Chemical Synthesis: TMABr is used as a starting material or intermediate in the synthesis of various pharmaceutical compounds.

4. Polymers & Resins

  • Template for Zeolite Nanocrystals: TMAB acts as a template in the hydrothermal synthesis of zeolite Y nanocrystals, influencing their size and yield.
  • Dehydrochlorination of PVC: TMAB can catalyze the removal of chlorine from poly(vinyl chloride), a process that can be used to modify or functionalize the polymer.
