Tikanga rokiroki
Whakatupato mo te rokiroki [Pokohia i roto i te whare putunga hauhautanga, whai hau. Kia matara atu i te ahi me nga puna wera. Kia kati te ipu. Me penapena motuhake mai i nga waiora, konumohe, me nga matū kai, me te karo i te rokiroki whakauru. Kua rite ki nga momo momo me te maha o nga taputapu ahi. Ko te waahi rokiroki me whakauru ki nga taputapu maimoatanga ohorere pakaru me nga taonga rokiroki tika.

Whakatau taumira:

Ko nga tikanga whakarite e whai ake nei. Ma te whakamahi i te chlorobenzene hei rauemi mata mo te whakamaarama ano, ka whiwhihia te p-dichlorobenzene, te o-dichlorobenzene me te m-dichlorobenzene. Ko te tikanga wehenga whanui e whakamahi ana i te dichlorobenzene whakauru mo te whakamarumaru tonu. Ko te para- me te meta-dichlorobenzene ka whakamakuku mai i te tihi o te pourewa, ko te p-dichlorobenzene ka whakahekehia e te mīti me te tioata, ka whakatikahia te waipiro whaea kia whiwhi meta-dichlorobenzene. Ko te o-dichlorobenzene he uira maturu i roto i te pourewa uira kia whiwhi o-dichlorobenzene. I tenei wa, ka whakamahia e te dichlorobenzene whakauru te tikanga o te adsorption me te wehenga, ma te whakamahi i te tatari molecular rite te adsorbent, me te wahanga hau i konatunatua te dichlorobenzene ka uru ki te pourewa adsorption, ka taea te whiriwhiri i te p-dichlorobenzene, a ko te toenga o te wai he meta me te ortho dichlorobenzene. Whakatikatika kia whiwhi m-dichlorobenzene me te o-dichlorobenzene. Ko 180-200°C te pāmahana adsorption, a ko te pēhanga adsorption he pēhanga noa.

1. Meta-phenylenediamine tikanga diazotization: Meta-phenylenediamine diazotized i roto i te aroaro o te konutai nitrite me te waikawa pungatara, te pāmahana diazotization ko 0~5 ℃, a ka hydrolyzed te wai diazonium ki te aroaro o te cuprous pūhaumāota ki te whakaputa intercalation. Dichlorobenzene.

2. Tikanga Meta-chloroaniline: Ma te whakamahi i te meta-chloroaniline hei rauemi mata, ka mahia te diazotization i te aroaro o te konutai nitrite me te waikawa waikawa, a ko te wai o te diazonium te wai i te aroaro o te cuprous chloride ki te whakaputa meta-dichlorobenzene.

I roto i nga tikanga whakareri i runga ake nei, ko te tikanga tino pai mo te mahi ahumahi me te utu iti ko te tikanga wehenga adsorption o te dichlorobenzene whakauru. He whare hanga kei Haina mo te whakaputa.

Ko te kaupapa matua:

1. Ka whakamahia i roto i te whakahiato waro. Ko te tauhohenga Friedel-Crafts i waenga i te m-dichlorobenzene me te chloroacetyl chloride ka puta te 2,4,ω-trichloroacetophenone, ka whakamahia hei takawaenga mo te miconazole tarukino antifungal whanui. Ko te tauhohenga chlorination ka mahia i te aroaro o te ferric chloride me te konumohe mercury, te nuinga o te whakaputa 1,2,4-trichlorobenzene. I roto i te aroaro o te whakakōkī, ka hydrolyzed i te 550-850°C ki te whakaputa m-chlorophenol me resorcinol. Ma te whakamahi i te waikura parahi hei whakakorikori, ka tauhohe ki te haukini i te 150-200°C i raro i te pehanga ki te whakaputa m-phenylenediamine.
2. Ka whakamahia ki te hanga waikano, nga takawaenga whakahiato waro me te whakarewa.
