| Abstract：Against the defects of current domestic synthesis process of 2,4-dichlorotoluene, improvement have been made by applying advanced alkaline rectification technologies. Consequently,The reaction yield is raised and rectification effect is bettered-reaction yield of chlorine is now over 75%;Utilization ratio of chlorine exceeds 92% and product qualification exceeds 99.5%. Therefore, production cost is cut down and pollution is minimized. All this indicates that the improvement is of remarkable economic and soc... |
