Indlela yokugcina:
Amanyathelo okukhusela xa ugcina, gcina kwindawo yokugcina izinto epholileyo, enomoya. Gcina kude nomlilo kunye nemithombo yobushushu. Gcina isikhongozeli sivaliwe kakuhle. Kufuneka sigcinwe ngokwahlukileyo kwii-oxidants, i-aluminium, kunye neekhemikhali ezityiwayo, kwaye uphephe ukugcinwa okuxutyiweyo. Sixhotyiswe ngeentlobo ezahlukeneyo kunye nobungakanani bezixhobo zomlilo. Indawo yokugcina kufuneka ixhotyiswe ngezixhobo zonyango olungxamisekileyo oluvuzayo kunye nezixhobo zokugcina ezifanelekileyo.

isisombululo sokusombulula:
Iindlela zokulungiselela zezi zilandelayo. Ukusebenzisa i-chlorobenzene njengezinto eziluhlaza zokufumana i-chlorination engaphezulu, kufunyanwa i-p-dichlorobenzene, i-o-dichlorobenzene kunye ne-m-dichlorobenzene. Indlela yokwahlula ngokubanzi isebenzisa i-dichlorobenzene exutyiweyo yokunyibilikisa okuqhubekayo. I-para- kunye ne-meta-dichlorobenzene zinyibilikiswa ukusuka phezulu kwinqaba, i-p-dichlorobenzene ikhutshwa ngokuqandisa kunye ne-crystallization, kwaye utywala obungumama buyalungiswa ukuze kufunyanwe i-meta-dichlorobenzene. I-o-dichlorobenzene inyibilikiswa kwi-flash tower ukuze kufunyanwe i-o-dichlorobenzene. Okwangoku, i-dichlorobenzene exutyiweyo isebenzisa indlela yokufunxa kunye nokwahlula, isebenzisa isihluzo se-molecular njenge-adsorbent, kwaye i-gas phase mixed dichlorobenzene ingena kwinqaba yokufunxa, enokukhetha ukufunxa i-p-dichlorobenzene, kwaye ulwelo oluseleyo yi-meta kunye ne-ortho dichlorobenzene. Ukulungiswa ukuze kufunyanwe i-m-dichlorobenzene kunye ne-o-dichlorobenzene. Ubushushu bokufunxa yi-180-200°C, kwaye uxinzelelo lokufunxa luxinzelelo oluqhelekileyo.

1. Indlela ye-diazonium ye-Meta-phenylenediamine: i-meta-phenylenediamine i-diazotized xa kukho i-sodium nitrite kunye ne-sulfuric acid, ubushushu be-diazotization yi-0 ~ 5℃, kwaye ulwelo lwe-diazonium lu-hydrolyzed xa kukho i-cuprous chloride ukuvelisa i-intercalation Dichlorobenzene.

2. Indlela ye-Meta-chloroaniline: Ukusebenzisa i-meta-chloroaniline njengezinto eziluhlaza, i-diazotization yenziwa xa kukho i-sodium nitrite kunye ne-hydrochloric acid, kwaye ulwelo lwe-diazonium lufakwa kwi-hydrolyzed xa kukho i-cuprous chloride ukuze kuveliswe i-meta-dichlorobenzene.

Phakathi kweendlela ezininzi zokulungiselela ezingentla, eyona ndlela ifanelekileyo yokuphucula amashishini kunye nexabiso eliphantsi yindlela yokwahlulahlula i-adsorption ye-dichlorobenzene exutyiweyo. Sele kukho iindawo zokuvelisa eTshayina.

Injongo ephambili:
1. Isetyenziswa kwi-organic synthesis. I-Friedel-Crafts reaction phakathi kwe-m-dichlorobenzene kunye ne-chloroacetyl chloride ivelisa i-2,4,ω-trichloroacetophenone, esetyenziswa njenge-intermediate ye-miconazole ye-broad-spectrum antifungal drug. I-chlorination reaction yenziwa xa kukho i-ferric chloride okanye i-aluminium mercury, ikakhulu ivelisa i-1,2,4-trichlorobenzene. Xa kukho i-catalyst, i-hydrolyzed kwi-550-850°C ukuvelisa i-m-chlorophenol kunye ne-resorcinol. Isebenzisa i-copper oxide njenge-catalyst, isabela ne-ammonia exineneyo kwi-150-200°C phantsi koxinzelelo ukuvelisa i-m-phenylenediamine.
2. Isetyenziswa ekwenzeni idayi, izinto ezidityanisiweyo ze-organic synthesis kunye nezinyibilikisi.
