【Abstract】 Catalytic synthesis of decabromodiphenyl ether was carried out by brominating diphenyl oxide in the presence of a novel metal catalyst HD 01. Uniform test design and simplex optimization were applied in the research, and optimum conditions for the reaction were obtained. Under the optimized conditions, molar ratio of diphenyl ether to bromine was 1∶30, ratio of catalyst HD 01 to diphenyl oxide 1∶5( m/m ), diphenyl ether feeding temperature 30 °C , reflux time 5.5 hours and the yield of purified decabromodiphenyl ether was up to 95.2%. A simple and convenient purification method was developed in order to solve the existing domestic problems in decabromodiphenyl ether production.更多还原
