BIOS 1146, 53. 2,4-Dimethylaniline. 2,4-Dimethylaniline. He whakamaoritanga no Ingarangi no Tiamana. Kaore i taku kohinga.

I roto i te ipu whakaiti 10 m3 me te miihini whakaheke, 1800 L o te wai, 500 L o te 20% otinga poka totoka me te 800 kg o te puehu rino i whakahokia mai i te puranga o mua i honoa. I tiimata te whakaohooho, ana kohuatia ana ki te whewhe na te whakawera koromamao noa. I roto i nga haora 20 2500 L (2800 kg) o 4-nitro m-xylene me te 2500 kg paura rino i taapirihia ki te kaiwhakaheke, i whakaritehia te utu mo te taapiri kia koropupuhia ana te ranunga, ko te mamaoa anake i te timatanga me te mutunga. Ko te kohu e mimiti mai ana i te kaiwhakahekehanga ka pupuhi i roto i te miihini nakahi ka whakahokia ki te kaiwhakaawe (na roto i te whakaranu, ka konatunatua ki te 4-nitro m-xylene) ka waimehihia te taapiri nitro i tenei ara kia iti ake ai te whakaiti. Ki te kore he xylene te tauira tauira whakamoana, kua oti te whakaiti ka oho mo etahi atu haora 4-5.
Whakamatau: Ko nga tauira ka tangohia mai i te kaitautoko mo te whakaheke i te kohu, ko te hinu mai i te hautanga kaore he tae, ka whakaputa i tetahi otinga maama me te waikawa waikawa.
Tango: ko nga rauemi mai i nga taputapu whakaheke ka pehihia ki te tangohanga ka mahia ki te 6000 L o te benzene i te 60 ° C ka oho, ka oho te ranunga mo te 1 haora ka waiho kia tu mo te 1 haora. Ko te hononga i waenga i te wai me te huka i whakatauhia ma te totohu i te taura i herea ki te reanga o te benzene engari ka rewa ki runga wai, ara, te hohonu o te papa whakapae. Ko te karamu o te ngongo rumaki rumaki e whakahekehia ana i raro i te taumata kua inehia, a ko te papa o te benzene o runga ka pehia ki roto i te awa me te hauota. E 6-7 nga wa e tangohia ai tenei tangohanga, a ka oti te tangohanga ka 3-5 kg ​​noa o te amine m-xylene e toe ana ki te tangohanga.
Ko nga tangohanga tuatahi e toru me nga tino taumaha o te 0.96, 0.925 me te 0.90 ka tukuna ki te kete whakangao whakaora benzene, ana ko nga tangohanga e whai ake nei me nga taumaha motuhake i raro ake i te 0.90 e whakamahia ana hei tangohanga mo nga tangohanga tuatahi, tuarua me te tuatoru o te puranga e whai ake nei. Ko te otinga benzene o te xylenolamine ka waihohia ki roto i te ipu pupuri ka tukuna ki te kohua whakahiato, ka whakaahuahia te benzene ka whakahokia ki te waahanga tangohanga hei whakamahi tonu. Ko te xylenolamine kei te noho tonu ki te kohanga rerenga.
Ko te toenga waahanga wairangi i roto i te tangohanga mamaoa tangohanga mo nga haora 4-5 hei whakahoki mai i te benzene, katahi ka ranua katoahia me te pehanga hau ki roto i te wehenga maara kari, i te pehanga ki te raro o te whakawehe ki te whakawhiti wai, paahihia te tere o te wai kia tere te waikura rino e rewa ana, na roto i te rerenga o runga ki te tauranga putunga puranga rino, i reira te waipuke waikura.
Ko te toenga rino kaore i rawekehia, he taumaha atu i te waikura rino, ka totohu ki raro o te kaiwehewehe porotakaroa i te rahinga 800-1000 kg ka whakahokia ki te kohinga kete whakaheke e whai ake nei.
Maama: Ko te hua miiharo mai i te pou whakamarumaru, i muri i te tangohanga o te benzene, ka whakawhitihia ki tetahi atu kohua rerenga me te pou, ka whakamanahia e te maamaatanga kotahi i te 20-30 mm me te 125-135 ° C. Ko te maamaatanga o te maamaa he 97-98%. Ko te maamaatanga o te maamaa he 97-98%.
Ko te kohinga katoa ko 90-91%. I muri i te maamaatanga, kia ma-Xylene-4-aniline kia maama me te kara kowhai i te tae. Ko te otinga i te waikawa waikawa me marama.

Tikanga whakahaere: (tauwehenga whakauru: paku). Taapirihia he wai, waikawa waikawa me te paura rino ki te pounamu 3000 ml me te whakaoho me te whakaheke i te taputapu, porohurihia mo te 15 meneti, ka ata whakarahi i te mahana ki te 90-98 ℃ ka tiimata te taapiri i te nitroxide. Mena kua ngaro te nitroxide, me taapiri tonu i te nitroxide, te tikanga i roto i nga haora 1.5-2. I muri i te taapiringa o te nitroxide, puritia te urupare ki te mahana i runga ake mo nga haora 2-2.5, kia ngaro ra ano te osmosis kowhai, kaore hoki he haunga o te nitroxide, ka tae te urupare whakaiti ki te mutunga. Ana ka whakamatao ki te 40-50 ℃, taapirihia te konutai peka waateate me te haamou ki te PH 7.5-8, ka mehu i nga urupare haamou ki te pepa taatari me te otinga waikawa alkali.
I te 2000 ml o nga pounamu e toru ki te whakahekenga o nga reactant, i mua i te pehanga i te ipu papa para-raro mo te waihanga kohu wai, ka whai atu ko te miihini ngongo totika, te kaiwhakarato i muri o te kaikawe whakahi, i te whakahekenga o te pounamu e toru-waha, hoatu he whakawera umu hiko, ka mau ana te kaikawe o te waikawa i te kapi, ka neke ki roto ki te okana wai kia wehea ki nga papa, am-xylene amine ki waho, ka paunatia kia wetewetehia.

Me kii atu: ko te Ahumahi Waikano o mua kaore i kaweake, no reira kaore i tangohia e CA, ana kaore ano kia tuhia e tetahi i Haina, na te mea kaore te China Chemical Information Centre e mohio mo taua mea!
