Whiwhi benzene

He maha ngā huarahi o te production ahumahi me te taiwhanga o te benzene, e rerekē i roto i te runga i te mea whiriwhiri te hua kei te rite te rauemi tīmatanga. production matū o nāianei rite taua piki pā ngā pūhui kakara, pērā i te hau Coke oumu hua i roto i te coking o waro. Ko ratou hautau waro uku whānui whakamahia me ngā i hanga i roto i Māturu o te hinu masivesivá.

Coking waro - te taahiraa tukanga nui i roto i te ahumahi maitai, he mea e tika ana ki te whiwhi Coke. Kahore he hiahia ki te whakaahua i roto i te taipitopito te hangarau katoa, e hāngai ana e te i runga i te faaineineraa o te benzene, Kati ra ki te mea e i roto i tenei take e hanga e te reira i roto i te taahiraa, ka decomposed te waro te me he Coke me volatiles matua nga hua whāwehe - Coke hau oumu. I roto i tona kohu he waro uku. A, no te haere tenei hau i roto i te pūnaha condenser, i reira te mea he wehenga o matū whakatu i te reira. I muri elektrofiltrovaniya Coke hau oumu Kei kē he rua o ngā pūhui matū waro , tae atu benzene. Tenei faaineineraa whakarite tona tukua benzene i roto i raw puka āhua rite ki te 10-11 kg ia tone o waro maroke.

taea hoki Coal uku ki te whiwhi benzene. Hangarau konei he haamana'oraa o te ara i roto i nei whakahaere te ki te whiwhi benzene i Coke hau oumu. Ko te meka ko, e i roto i iho waro uku - he matatini kaua i roto i te ranunga wähanga hanganga o rerekē momo o ngā pūhui matū waro kakara. Ano, ara tenei ra, e kore e matau te hanganga o te pūhui tino, a ko te kupu pumau te oraraa o neke atu i te 500 (!) Wae. hangarau tukatuka Ko te tukanga o te rua-atamira wehenga kāpia ki hautau motuhake. Hoki tenei whakaaro e i raro ia o ratou ki te mahi o kawakore ki te tango wahi waikawa. i hanga e nga totoka hua - anthracene me te naphthalene, me te marama, ngā nei i roto i te hanganga me te benzene.

horahia te ahumahi whiwhi benzene i ahua raw, te benzene masivesivá pera-ka karanga. Ki te whiwhi pūhui parakore, me kia horoia benzene masivesivá i pūhui whanariki. I roto i tenei tukanga wehewehe rua ngā wāhanga. Ko te tuatahi puta tango tika o poke whanariki, me te rua o te ranunga wehea pure e te Māturu. Ko tētahi o nga hua o tenei wehenga ka kia benzene.

Ko te puna nui o ngā mea kakara, ko te hinu. Ko te aha arotahi benzenes production hou i runga i tenei hua.

I tawhiti ano Benzene i acetylene. Ko tēnei rauemi i raro i ngā āhuatanga noa ko te hau, ko reira te huitahi, ngā rewakore i roto i te wai, he mama atu i te hau. I roto i te āhuatanga matū o te hau kua te kaha ki te polymerize, a na reira whakamahia i roto i te ahumahi mō te whakaputa benzene i acetylene. Ko te fafau atu i te hi'oraa o te hanga me te pupuri i ngā āhuatanga mo te tauhohenga matū tenei tikanga. Ko te meka e acetylene, i roto ano, Ko te tino taikaha, no te mea i tona whakamahi i roto i te ahumahi tā te hiahia ki te ū ki tino ako hangarau me te taputapu motuhake, rawa wera-ātete. I te wa ano, i te aroaro o whiwhi i te acetylene i benzene, ki te whakatutuki i rawaka te pāmahana ki te 400 C me te mau i te reira i roto i te aroaro o te graphite. whakaarohia tenei tikanga i roto i 1866 i te kēmihi French M. Berthelot, Heoi, ko tino iti te tukua taonga. Na reira, i roto i te hangarau o te tenei ra, ko te whakamahi whānui o ngā momo o kaiwhakakökï me mo whakatere i te tauhohenga me te whakanui ake i te tukua o te benzene parakore.

I raro i ngā āhuatanga taiwhanga, e kore te nuinga o te wā whiwhi benzene, engari whakatika ki te otiia e hiahia ana, te tikanga alloying te whakamahi i te waikawa-mangeo ki te alkali. Ko te hua o tenei tauhohenga ko benzene.
