Continuous Synthesis and Separation of p-Bromobenzyl Bromide Using Atom-Efficient Bromination of p-Bromotoluene without Any Organic Effluent: Potential for Green Industrial Practice

Abstract: This work focuses on the bromination of p-bromotoluene (PBT) using different brominating agents such as liquid Br2, NaBr–NaBrO3, NaBr–NaBrO3–NaCl, NaBr–H2O2, and HBr–H2O2. NaBr–NaBrO3–NaCl is an eco-friendly brominating agent obtained from a bromine recovery plant. Both NaBr–NaBrO3 and NaBr–NaBrO3–NaCl were found to be nonhazardous and efficient brominating agents. Pure NaBr–NaBrO3 resulted in the best PBT conversion with 79.7% Br atom efficiency in water and 98.2% average Br atom efficiency using dichloroetha… Show more
