Habka kaydinta:
Ka taxadar kaydinta, ku kaydi bakhaar qabow oo hawo leh. Ka fogow dabka iyo ilaha kulaylka. Weelka si adag u xidh. Waa in si gooni ah loo kaydiyaa oksaydhiyeyaasha, aluminium, iyo kiimikooyinka la cuni karo, kana fogow kaydinta isku dhafan. Lagu qalabeeyay noocyada ku habboon iyo tirada qalabka dabka. Goobta wax lagu kaydiyo waa in lagu qalabeeyaa qalab daawaynta degdega ah ee daadsan iyo agab kayd oo ku haboon.

xallinta xallinta:
Habka diyaarinta waa sida soo socota. Isticmaalka chlorobenzene sida walxo ceeriin ah oo koloriin dheeri ah, p-dichlorobenzene, o-dichlorobenzene iyo m-dichlorobenzene ayaa la helay. Habka kala-soocidda guud waxay isticmaashaa dichlorobenzene isku dhafan si ay u nadiifiso joogtada ah. Para- iyo meta-dichlorobenzene ayaa laga soo miiqayaa meesha sare ee munaaradda, p-dichlorobenzene waxaa soo dajiya qaboojin iyo crystallization, ka dibna khamriga hooyada waa la saxayaa si loo helo meta-dichlorobenzene. O-dichlorobenzene waxa ay si toos ah ugu daaran tahay munaaradda flash-ka si loo helo o-dichlorobenzene. Waqtigan xaadirka ah, dichlorobenzene-ka isku-dhafka ah wuxuu qaataa habka adsorption iyo kala-soocidda, iyadoo la adeegsanayo shaandho molecular sida adsorbent, iyo wajiga gaaska isku dhafan ee dichlorobenzene wuxuu galaa munaaradda xayeysiinta, kaas oo si door ah u adsorb kara p-dichlorobenzene, dareeraha haraaga ah waa meta iyo ortho dichlorobenzene. Sixitaanka si loo helo m-dichlorobenzene iyo o-dichlorobenzene. Heerkulka adsorption waa 180-200 ° C, cadaadiska adsorption waa cadaadis caadi ah.

1. Meta-phenylenediamine diazonium Habka: meta-phenylenediamine waxaa lagu diazotized joogitaanka sodium nitrite iyo sulfuric acid, heerkulka diazotization waa 0～5℃, iyo dareeraha diazonium waa hydrolyzed joogitaanka chloride cuprous si ay u soo saaraan intercalation Dichlorobenzene.

2. Habka Meta-chloroaniline: Isticmaalka meta-chloroaniline sida alaabta ceeriin, diazotization waxaa lagu fuliyaa joogitaanka sodium nitrite iyo hydrochloric acid, iyo dareeraha diazonium waa hydrolyzed joogitaanka koloride koobrous si ay u abuuraan meta-dichlorobenzene.

Mid ka mid ah hababka diyaarinta ee dhowr ah ee kor ku xusan, habka ugu habboon ee warshadaynta iyo kharashka hoose waa habka kala-soocidda ee dichlorobenzene isku dhafan. Waxaa horeba u jiray tas-hiilaad wax-soo-saar oo Shiinaha ku yaalla.

Ujeedada ugu weyn:
1. Waxaa loo isticmaalaa isku-dhafka dabiiciga ah. Dareen-celinta Friedel-Crafts ee u dhaxaysa m-dichlorobenzene iyo chloroacetyl chloride waxay soo saartaa 2,4, ω-trichloroacetophenone, taas oo loo isticmaalo dhexdhexaadinta daawada fangas ballaaran ee miconazole. Falcelinta koloriinta waxaa lagu fuliyaa joogitaanka ferric chloride ama aluminium meerkuri, inta badan soo saarta 1,2,4-trichlorobenzene. Iyadoo ay jirto wax-qabad, waxaa lagu shubaa 550-850 ° C si loo dhaliyo m-chlorophenol iyo resorcinol. Isticmaalka oksijiinta naxaasta ah ee kicinta ah, waxay la falgashaa ammonia xoogga leh 150-200 ° C cadaadis si ay u dhaliso m-phenylenediamine.
2. Loo isticmaalo wax soo saarka dheeha, dhex-dhexaadinta isku-dhafka organic iyo dareerayaasha.
