| Abstract: | According to the main problem of current synthesis process of 2,4 -dichlorotoluene,through improving chlorinated synthesis process,using advanced rectification technology,the reaction yield of chlorine is raised to 78%,and the utilization ratio of chlorine is now raised to 94%,the system consumption of steam and electricity is also reduced.There- fore,production cost is cut down,corrosion and pollution is minimized.All this indicates that the improvement is of remarka- ble economic and social benefits with prospects of being applied extensively. |
