M-dichlorobenzene yog ib qho tseem ceeb nruab nrab ntawm cov tshuaj, tshuaj tua kab, zas xim thiab lwm yam lag luam, thiab yog ib qho tseem ceeb raw khoom rau cov tshuaj tua kab mob hauv kev lag luam kws tshuaj.
Txij li xyoo 2016, peb lub tuam txhab tau koom nrog kev tshawb fawb thiab kev tsim kho nrog Shanghai Petrochemical Research Institute los tsim m-dichlorobenzene los ntawm kev siv isomerism hloov tshuab thiab tau thov rau patent. Lub peev xwm tsim tau mus txog 12,000 tons. Tam sim no, cov cuab yeej 5,000 tuj tau muab tso rau hauv kev tsim khoom, thiab qhov thib ob 7,000 tuj khoom raug teeb tsa. Tom qab ncav cuag lub hom phiaj tso tawm peb lub tuam txhab kev lag luam feem ntawm M-dichlorobenzene yuav suav txog ntau dua 60%.
