Description and Uses
N,N-Dimethylbenzylamine was used in the synthesis of bis[(N,N-dimethylamino)benzyl] selenide. It has been used as catalyst during curing reaction of formulations of diglycidyl ether of bisphenol A and tetrahydrophthalic anhydride. It undergoes directed ortho metalation with butyl lithium. It reacts with methyl iodide to get ammonium salt, which is used as phase transfer catalysts. Further, it is used as a catalyst for the formation of polyurethane foams and epoxy resins.
