Indlela yokugcina:
Izinyathelo zokuphepha, gcina endaweni epholile, nengena umoya.Gcina kude nomlilo nemithombo yokushisa.Gcina isitsha sivalwe ngokuqinile.Kufanele igcinwe ngokuhlukana nama-oxidants, i-aluminium, namakhemikhali adliwayo, futhi igweme ukugcinwa okuxubile.Ifakwe izinhlobonhlobo ezifanele kanye nenani lamathuluzi omlilo.Indawo yokugcina impahla kufanele ifakwe izinto zokwelashwa eziphuthumayo ezivuzayo kanye nezinto ezifanele zokugcina.

xazulula isixazululo:
Izindlela zokulungiselela zimi kanje.Ukusebenzisa i-chlorobenzene njengento eluhlaza ukuze kuqhutshekwe ne-chlorination, kutholakala i-p-dichlorobenzene, i-o-dichlorobenzene kanye ne-m-dichlorobenzene.Indlela yokuhlukanisa evamile isebenzisa i-dichlorobenzene exubile ukuze kuphuzwe uketshezi oluqhubekayo.I-para- kanye ne-meta-dichlorobenzene i-distilled kusukela phezulu kombhoshongo, i-p-dichlorobenzene inethwa ukuqandisa nokucwebezela, bese uphuzo olungumama luyalungiswa ukuze kutholwe i-meta-dichlorobenzene.I-o-dichlorobenzene i-flash distilled kumbhoshongo we-flash ukuze ithole i-o-dichlorobenzene.Njengamanje, i-dichlorobenzene exubile isebenzisa indlela yokukhanga nokuhlukanisa, isebenzisa isisefo samangqamuzana njenge-adsorbent, futhi isigaba segesi esixutshwe i-dichlorobenzene singena embhoshongweni we-adsorption, ongakhetha ngokukhetha i-p-dichlorobenzene, futhi uketshezi olusele luyi-meta ne-ortho dichlorobenzene.Ukulungiswa kabusha ukuze kutholwe i-m-dichlorobenzene ne-o-dichlorobenzene.Izinga lokushisa le-adsorption liyi-180-200 ° C, futhi ingcindezi ye-adsorption ingcindezi evamile.

1. Indlela ye-Meta-phenylenediamine diazonium: i-meta-phenylenediamine yenziwa i-diazotized phambi kwe-sodium nitrite ne-sulfuric acid, izinga lokushisa le-diazotization lingu-0～5℃, futhi uketshezi lwe-diazonium lufakwa nge-hydrolyzed phambi kwe-cupurous chloride ukuze kukhiqizwe i-Dichlorobenzene intercalation.

2. Indlela ye-Meta-chloroaniline: Kusetshenziswa i-meta-chloroaniline njengento eluhlaza, i-diazotization yenziwa phambi kwe-sodium nitrite ne-hydrochloric acid, futhi uketshezi lwe-diazonium lufakwa nge-hydrolyzed phambi kwe-cuprous chloride ukuze kukhiqizwe i-meta-dichlorobenzene.

Phakathi kwalezi zindlela zokulungiselela ezimbalwa ezingenhla, indlela efaneleke kakhulu yokwenza izimboni kanye nezindleko eziphansi yindlela yokuhlukanisa i-adsorption ye-dichlorobenzene exubile.Sekuvele kunezindawo zokukhiqiza eChina ezizokhiqizwa.

Inhloso eyinhloko:
1. Isetshenziswa ku-organic synthesis.Ukusabela kwe-Friedel-Crafts phakathi kwe-m-dichlorobenzene ne-chloroacetyl chloride kukhiqiza i-2,4,ω-trichloroacetophenone, esetshenziswa njengendawo emaphakathi yomuthi we-antifungal obanzi we-miconazole.Ukusabela kwe-chlorination kwenziwa phambi kwe-ferric chloride noma i-aluminium mercury, ikakhulukazi ikhiqiza i-1,2,4-trichlorobenzene.Lapho kukhona i-catalyst, i-hydrolyzed ku-550-850°C ukuze ikhiqize i-m-chlorophenol ne-resorcinol.Isebenzisa i-copper oxide njenge-catalyst, isabela nge-ammonia egxilile ku-150-200°C ngaphansi kwengcindezi yokwenza i-m-phenylenediamine.
2. Isetshenziswa ekwenzeni udayi, i-organic synthesis intermediates kanye nezincibilikisi.
