isisombululo sokusombulula:
Iindlela zokulungiselela zezi zilandelayo. Ukusebenzisa i-chlorobenzene njengento ekrwada yokuqhubela phambili i-chlorination, i-p-dichlorobenzene, i-o-dichlorobenzene kunye ne-m-dichlorobenzene ifunyenwe. Indlela yokwahlula ngokubanzi isebenzisa i-dichlorobenzene exubeneyo kwi-distillation eqhubekayo. I-para- kunye ne-meta-dichlorobenzene idistilled ukusuka phezulu kwinqaba, i-p-dichlorobenzene igalelwa ngokukhenkceza kunye necrystallization, kwaye utywala lukamama luyalungiswa ukuze lufumane i-meta-dichlorobenzene. I-o-dichlorobenzene i-flash distilled kwi-flash tower ukufumana i-o-dichlorobenzene. Okwangoku, i-dichlorobenzene exubeneyo ithatha indlela ye-adsorption kunye nokwahlula, isebenzisa i-molecular sieve njenge-adsorbent, kunye nesigaba segesi esixubene ne-dichlorobenzene singena kwi-adsorption tower, enokukhetha i-adsorb p-dichlorobenzene, kwaye ulwelo oluyintsalela yi-meta kunye ne-ortho dichlorobenzene. Ukulungiswa ukufumana i-m-dichlorobenzene kunye ne-o-dichlorobenzene. Ukushisa kwe-adsorption yi-180-200 ° C, kwaye uxinzelelo lwe-adsorption luxinzelelo oluqhelekileyo.

1. Meta-phenylenediamine diazonium method: meta-phenylenediamine is diazotized in the presence of sodium nitrite and sulfuric acid, the diazotization temperature is 0～5℃, kunye nediazonium liquid i-hydrolyzed phambi kwe cuprous chloride ukuvelisa intercalation Dichlorobenzene.

2. Indlela ye-Meta-chloroaniline: Ukusebenzisa i-meta-chloroaniline njengento eluhlaza, i-diazotization iqhutyelwa phambi kwe-nitrite ye-sodium kunye ne-hydrochloric acid, kwaye i-diazonium liquid i-hydrolyzed phambi kwe-cupurous chloride ukuvelisa i-meta-dichlorobenzene.

Phakathi kweendlela ezininzi zokulungiselela ezingentla, eyona ndlela ifanelekileyo yoshishino kunye neendleko eziphantsi yindlela yokwahlula i-adsorption yedichlorobenzene exutyiweyo. Sele kukho iindawo zokuvelisa e-China zokuvelisa.

Injongo ephambili:
1. Isetyenziswe kwi-organic synthesis. I-reaction ye-Friedel-Crafts phakathi kwe-m-dichlorobenzene kunye ne-chloroacetyl chloride ivelisa i-2,4,ω-trichloroacetophenone, esetyenziswa njengendawo ephakathi kwi-wide-spectrum antifungal drug miconazole. Ukusabela kwe-chlorination kuqhutyelwa phambi kwe-chloride ye-ferric okanye i-aluminium mercury, ngokuyinhloko ivelisa i-1,2,4-trichlorobenzene. Xa kukho i-catalyst, i-hydrolyzed kwi-550-850 ° C ukuvelisa i-m-chlorophenol kunye ne-resorcinol. Ukusebenzisa i-copper oxide njenge-catalyst, isabela nge-ammonia egxininisiweyo kwi-150-200 ° C phantsi koxinzelelo lokuvelisa i-m-phenylenediamine.
2. Isetyenziselwa ukwenza idayi, i-organic synthesis intermediates kunye ne-solvents.
