Nzira yekuchengetedza:
Chengetedzo dzekuchengetedza, chengeta munzvimbo inotonhorera, ine mhepo yekuchengetera mhepo. Ramba kure nemoto nekupisa. Chengetedza mudziyo wakavharwa zvakasimba. Inofanirwa kuchengetwa zvakasiyana kubva kune oxidants, aluminiyamu, uye makemikari anodyika, uye kudzivirira kusanganiswa kuchengetedza. Yakashongedzerwa nemhando yakakodzera uye huwandu hwemidziyo yemoto. Imba yekuchengetera inofanirwa kuve neyakavharika yekukurumidzira kurapwa michina uye yakakodzera yekuchengetedza zvinhu.

gadzirisa sarudzo:
Nzira dzekugadzirira dzinotevera. Kushandisa chlorobenzene sechinhu chakabikwa chekuwedzera klorini, p-dichlorobenzene, o-dichlorobenzene uye m-dichlorobenzene inowanikwa. Iyo yakawanda yekuparadzanisa nzira inoshandisa yakasanganiswa dichlorobenzene yekuenderera mberi distillation. Iyo para- uye meta-dichlorobenzene yakasvibiswa kubva pamusoro peshongwe, p-dichlorobenzene inonatswa nechando uye crystallization, uye mai doro rinobva ragadziriswa kuti riwane meta-dichlorobenzene. Iyo o-dichlorobenzene inopenya yakanyungudutswa mushongwe yekupenya kuti iwane o-dichlorobenzene. Parizvino, dichlorobenzene yakasanganiswa inotora nzira yekushambadza uye kuparadzanisa, kushandisa molecular sieve se adsorbent, uye gasi gasi rakasanganiswa dichlorobenzene rinopinda mushongwe yeadsorption, iyo inogona kusarudza adsorb p-dichlorobenzene, uye mvura yakasara ndeye meta uye ortho dichlorobenzene. Kugadzirisa kuwana m-dichlorobenzene uye o-dichlorobenzene. Iyo adsorption tembiricha ndeye 180-200 ° C, uye adsorption pressure ndeye yakajairika kumanikidza.

1. Meta-phenylenediamine diazonium nzira: meta-phenylenediamine inonzi diazotized pamberi pe sodium nitrite uye sulfuric acid, tembiricha ye diazotization i 0～5 ℃, uye iyo diazonium fluid inogadzirwa ne hydrolyzed pamberi pe cuprous chloride kuti ibudise intercalation Dichlorobenzene.

2. Meta-chloroaniline nzira: Kushandisa meta-chloroaniline sechinhu chakasvibiswa, diazotization inoitwa pamberi pe sodium nitrite uye hydrochloric acid, uye diazonium mvura inogadziriswa hydrolyzed muhupo hwe cuprous chloride kuti ibudise meta-dichlorobenzene.

Pakati penzira dzakati wandei dzekugadzirira, nzira yakanyatsokodzera maindasitiri uye mutengo wakaderera ndiyo adsorption yekuparadzanisa nzira yedichlorobenzene yakasanganiswa. Iko kune kare zvigadzirwa zvekugadzira muChina zvekugadzira.

Chinangwa chikuru:
1. Inoshandiswa mune organic synthesis. The Friedel-Crafts reaction pakati pe-m-dichlorobenzene uye chloroacetyl chloride inobereka 2,4,ω-trichloroacetophenone, iyo inoshandiswa sepakati pe-broad-spectrum antifungal drug miconazole. Iyo chlorination reaction inoitwa pamberi peferric chloride kana aluminium mercury, kunyanya kugadzira 1,2,4-trichlorobenzene. Muhupo hwechigadziriso, inoiswa hydrolyzed pa550-850 ° C kugadzira m-chlorophenol uye resorcinol. Ichishandisa copper oxide sechinhu chinokonzeresa, inopindirana neconcentrated ammonia pa150-200°C pasi pekumanikidzwa kugadzira m-phenylenediamine.
2. Inoshandiswa mukugadzira dhayi, organic synthesis intermediates uye solvents.
