APPLICATION

Tetrabutylammonium bromide (TBAB) might be utilized as a part of the liquid condition in the below procedures:

·       Synthesis of isophthalic acid

·       Synthesis of alkyl-secondary pyrroles without impetus and natural solvent

·       Synthesis of dithioacetals against acetals through transthioacetalisation in a dissolvable free condition

·       Synthesis of polyamides through the polymerization of diisocyanates as well as terephthalic corrosive
