Abstract
Use AlCl_3/S_2Cl_2 as catalyst, the synthesis of 3,4-dichlorotoluene from p-chlorotoluene by chlorination was studied. By orthogonal test, the best condition for the preparation of 3,4-dichlorotoluene is found to be temp.=100℃,cat.%=20%, AlCl_3∶S_2Cl_2=1∶05,the selectivity of 3,4-dichlorotoluene in dichlorotoluenes reached 51%, its yield came to 415%.
