Txoj kev khaws cia:
Cov kev ceev faj rau kev khaws cia, khaws cia rau hauv lub tsev khaws khoom txias thiab muaj cua nkag. Khaws cia kom deb ntawm hluav taws thiab cua sov. Khaws lub thawv kom nruj. Nws yuav tsum khaws cia cais ntawm cov tshuaj oxidants, txhuas, thiab cov tshuaj noj tau, thiab tsis txhob khaws cia sib xyaw. Nruab nrog ntau yam thiab ntau npaum li cas ntawm cov khoom siv tua hluav taws. Thaj chaw khaws cia yuav tsum tau nruab nrog cov khoom siv kho mob thaum muaj xwm txheej ceev thiab cov ntaub ntawv khaws cia tsim nyog.

kev daws teeb meem:
Cov txheej txheem npaj yog raws li nram no. Siv chlorobenzene ua cov khoom siv raw rau kev ntxiv chlorination, p-dichlorobenzene, o-dichlorobenzene thiab m-dichlorobenzene tau txais. Txoj kev sib cais dav dav siv cov dichlorobenzene sib xyaw rau kev sib cais tas mus li. Cov para- thiab meta-dichlorobenzene yog distilled los ntawm sab saum toj ntawm lub pej thuam, p-dichlorobenzene yog precipitated los ntawm kev khov thiab crystallization, thiab cov kua dej niam ces raug kho kom tau txais meta-dichlorobenzene. Lub o-dichlorobenzene yog flash distilled hauv lub pej thuam flash kom tau txais o-dichlorobenzene. Tam sim no, cov dichlorobenzene sib xyaw siv txoj kev adsorption thiab kev sib cais, siv cov molecular sieve ua adsorbent, thiab cov roj theem sib xyaw dichlorobenzene nkag mus rau hauv lub pej thuam adsorption, uas tuaj yeem xaiv adsorbent p-dichlorobenzene, thiab cov kua seem yog meta thiab ortho dichlorobenzene. Kev kho kom tau txais m-dichlorobenzene thiab o-dichlorobenzene. Qhov kub adsorption yog 180-200 ° C, thiab lub siab adsorption yog lub siab ib txwm.

1. Txoj kev siv Meta-phenylenediamine diazonium: meta-phenylenediamine raug diazotized nyob rau hauv qhov muaj sodium nitrite thiab sulfuric acid, qhov kub diazotization yog 0 ~ 5 ℃, thiab cov kua diazonium raug hydrolyzed nyob rau hauv qhov muaj cuprous chloride los tsim cov intercalation Dichlorobenzene.

2. Txoj kev Meta-chloroaniline: Siv meta-chloroaniline ua cov khoom siv raw, diazotization yog ua tiav nyob rau hauv qhov muaj sodium nitrite thiab hydrochloric acid, thiab cov kua diazonium yog hydrolyzed nyob rau hauv qhov muaj cuprous chloride los tsim meta-dichlorobenzene.

Ntawm ntau txoj kev npaj saum toj no, txoj kev tsim nyog tshaj plaws rau kev lag luam thiab tus nqi qis dua yog txoj kev sib cais adsorption ntawm cov dichlorobenzene sib xyaw. Twb muaj cov chaw tsim khoom hauv Suav teb rau kev tsim khoom.

Lub hom phiaj tseem ceeb:
1. Siv rau hauv kev tsim cov organic. Qhov kev sib xyaw ua ke ntawm Friedel-Crafts ntawm m-dichlorobenzene thiab chloroacetyl chloride ua rau muaj 2,4,ω-trichloroacetophenone, uas yog siv ua ib qho nruab nrab rau cov tshuaj tua kab mob broad-spectrum miconazole. Qhov kev sib xyaw ua ke ntawm chlorination yog ua tiav thaum muaj ferric chloride lossis txhuas mercury, feem ntau yog tsim 1,2,4-trichlorobenzene. Thaum muaj ib qho catalyst, nws yog hydrolyzed ntawm 550-850 ° C los tsim m-chlorophenol thiab resorcinol. Siv tooj liab oxide ua ib qho catalyst, nws reacts nrog concentrated ammonia ntawm 150-200 ° C nyob rau hauv siab los tsim m-phenylenediamine.
2. Siv rau hauv kev tsim cov xim, cov organic synthesis intermediates thiab cov kuab tshuaj.
